I noticed that you took some time back in late 2009 to 'consolidate' the
split format-strings present in the bonding driver at the time and I've
decided I'm fine to leave them the way they are. The main point of my
patch was to change the output and I would like to get that included.
Here is my updated patch...
Subject: [PATCH net-next-2.6 v2] bonding: reduce noise during init
Many are using sysfs to configure bonding rather than module options, so
there is no need for bonding to throw this warning in normal cases.
Keep the message around when debugging is enabled as it might be useful
for someone desperate enough to enable debugging, but eliminate it
otherwise.

When a bond contains a device where one name is the subset of another
(eth1 and eth10, for example), one cannot properly set the primary
device or the currently active device.
This was reported and based on work by Takuma Umeya. I also verified
the problem and tested that this fix resolves it.
V2: A few did not like the the current code or my changes, so I
refactored bonding_store_primary and bonding_store_active_slave to be a
bit cleaner, dropped the use of strnicmp since we did not really need
the comparison to be case insensitive, and formatted the input string
from sysfs so a comparison to IFNAMSIZ could be used.
I also discovered an error in bonding_store_active_slave that would
modify bond->primary_slave rather than bond->curr_active_slave before
forcing the bonding driver to choose a new active slave.
V3: Actually sending the proper patch....

After the last patch, We are left in a state in which only drivers calling
ether_setup have IFF_TX_SKB_SHARING set (we assume that drivers touching real
hardware call ether_setup for their net_devices and don't hold any state in
their skbs. There are a handful of drivers that violate this assumption of
course, and need to be fixed up. This patch identifies those drivers, and marks
them as not being able to support the safe transmission of skbs by clearning the
IFF_TX_SKB_SHARING flag in priv_flags

On the recent i.mx (mx25/50/53), there is a gasket inside fec
controller which needs to be enabled no matter phy works in MII
or RMII mode.
The current code enables the gasket only when phy interface is RMII.
It's broken when the driver works with a MII phy. The patch uses
platform_device_id to distinguish the SoCs that have the gasket and
enables it on these SoCs for both MII and RMII mode.

Martin Wilck <martin.wilck@ts.fujitsu.com> reported that systems using
the ixgbe-driver that were capable of WoL were rebooting almost as soon
as they were shut down. This is because the default WoL settings
enabled magic packet, broadcast, unicast, and multicast.
Other Intel devices seem to use the stored eeprom value for initial WoL
capabilities. The 82578DM (e1000e) and 82576 (igb) the devices I looked
at had only the magic packet enabled in the eeprom, so that seems
appropriate on ixgbe-based devices as well. I set the WoL options on my
82578DM to be the same default as the ixgbe devices (umbg) and saw the
same as Martin -- almost as soon as my box shutdown, it booted again.
This patch changes the default to only be the magic packet. This is the
same as the default for most Intel and non-Intel hardware currently
upstream.

Prior to this change, most PHY configuration parameters were passed
into the STMMAC device as a separate PHY device. As well as being
unusual, this made it difficult to make changes to the MAC/PHY
relationship.
This patch moves all the PHY parameters into the MAC configuration
structure, mainly as a separate structure. This allows us to completely
ignore the MDIO bus attached to a stmmac if desired, and not create
the PHY bus. It also allows the stmmac driver to use a different PHY
from the one it is connected to, for example a fixed PHY or bit banging
PHY.
Also derive the stmmac/PHY connection type (MII/RMII etc) from the
mode can be passed into <platf>_configure_ethernet.

Michal Miroslaw's rejected patch:
[PATCH v2 10/46] net: jme: convert to generic DMA API
Pointed out the issue also, thank you Michal.
But the fix was incorrect. It would unmap needed address

Got lots of feedback from End user and Gentoo Bugzilla.

For ad-hoc mode, RA is created for each peer connected. In case of
multicast traffic new RA will be created for each multicast
address. While processing Tx packets we have to go through this
RA list. We can avoid some RA nodes by sharing same RA for both
multicast and broadcast packets.
Therefore "memset(0xff)" is used to treat multicast packet as broadcast
one while choosing RA.

Implement WoWLAN support in iwlagn. The device
supports a number of wakeup triggers and can do

out of the wowlan uCode to stay connected safely.

As I just discovered while doing WoWLAN, HW crypto
is done wrong for GTKs: they should be programmed
for the AP station ID (in the managed mode case)
and the HW can actually deal with multiple group
keys per station as well (which is useful in IBSS
RSN but that I've chosen not to use this).
To fix all this, modify the way keys are sent to
the device and key offsets are allocated. After
these changes, key offsets are stored into the
hw_key_idx which we can then track for the key
lifetime, not relying on our sta_cmd array. WEP
default keys get special treatment, of course.
Additionally, since I had the API for it, we can
now pre-fill TKIP phase 1 keys for RX now that we
can obtain the P1K from mac80211, a capability I
had added for WoWLAN initially.
Finally, some keys simply don't need to be added
into the device's key cache -- a key that won't
be used for RX is only needed in the TX header,
so "pretend" to have accepted any key without
adding it into the device -- no need to use up
key space there for it.

Call iwl_probe with a ready iwl_bus struct. This means that the bus layer

The device specific struct is allocated together with the common iwl_bus struct
by the bus specific layer. The pointer to the aggregate struct is passed to the
upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus.
The private data given to the PCI subsystem is now iwl_bus and not iwl_priv.

Both ath5k_hw and ath5k_softc represent one instance of the hardware.
This duplication is historical and is not needed anymore.
Keep the name "ath5k_hw" for the merged structure and "ah" for the
variable pointing to it. "ath5k_hw" is shorter than "ath5k_softc", more
descriptive and more widely used.
Put the combined structure to ath5k.h where the old ath5k_softc used to
be. Move some code from base.h to ath5k.h as needed.
Remove memory allocation for struct ath5k_hw and the corresponding error
handling. Merge iobase and ah_iobase fields.

Based on original patch and description from Flavio Leitner <fbl@redhat.com>
When bnx2_reset_task() is called, it will stop,
(re)initialize and start the interface to restore
the working condition.
The bnx2_init_nic() calls bnx2_reset_nic() which will
reset the chip and then calls bnx2_free_skbs() to free
all the skbs.
The problem happens when bnx2_init_chip() fails because
bnx2_reset_nic() will just return skipping the ring
initializations at bnx2_init_all_rings(). Later, the
reset task starts the interface again and the system
crashes due a NULL pointer access (no skb in the ring).
To fix it, we call dev_close() if bnx2_init_nic() fails.
One minor wrinkle to deal with is the cancel_work_sync()
call in bnx2_close() to cancel bnx2_reset_task(). The
call will wait forever because it is trying to cancel
itself and the workqueue will be stuck.
Since bnx2_reset_task() holds the rtnl_lock() and checks
for netif_running() before proceeding, there is no need
to cancel bnx2_reset_task() in bnx2_close() even if
bnx2_close() and bnx2_reset_task() are running concurrently.
The rtnl_lock() serializes the 2 calls.
We need to move the cancel_work_sync() call to
bnx2_remove_one() to make sure it is canceled before freeing
the netdev struct.

Commit 5f77898de1 does not completely
fix the problem of handling allocations with irqs disabled.. The
below patch on top of it fixes the problem completely.
Based on review by "Ivan Vecera" <ivecera@redhat.com>..
"
Small note, the root of the problem was that non-atomic allocation was requested with IRQs disabled. Your patch description does not contain wwhy were the IRQs disabled.
The function bnad_mbox_irq_alloc incorrectly uses 'flags' var for two different things, 1) to save current CPU flags and 2) for request_irq
call.
First the spin_lock_irqsave disables the IRQs and saves _all_ CPU flags (including one that enables/disables interrupts) to 'flags'. Then the 'flags' is overwritten by 0 or 0x80 (IRQF_SHARED). Finally the spin_unlock_irqrestore should restore saved flags, but these flags are now either 0x00 or 0x80. The interrupt bit value in flags register on x86 arch is 0x100.
This means that the interrupt bit is zero (IRQs disabled) after spin_unlock_irqrestore so the request_irq function is called with disabled interrupts.

Fix the condition where PS3 network RX hangs when no network
TX is occurring by calling gelic_card_enable_rxdmac() during
RX_DMA_CHAIN_END event processing.
The gelic hardware automatically clears its RX_DMA_EN flag when
it detects an RX_DMA_CHAIN_END event. In its processing of
RX_DMA_CHAIN_END the gelic driver is required to set RX_DMA_EN
(with a call to gelic_card_enable_rxdmac()) to restart RX DMA
transfers. The existing gelic driver code does not set
RX_DMA_EN directly in its processing of the RX_DMA_CHAIN_END
event, but uses a flag variable card->rx_dma_restart_required
to schedule the setting of RX_DMA_EN until next inside the
interrupt handler.
It seems this delayed setting of RX_DMA_EN causes the hang since
the next RX interrupt after the RX_DMA_CHAIN_END event where
RX_DMA_EN is scheduled to be set will not occur since RX_DMA_EN
was not set. In the case were network TX is occuring, RX_DMA_EN
is set in the next TX interrupt and RX processing continues.

Overview:
Support mapping of priorities to traffic classes and
traffic classes to transmission queues ranges in the net device.
The queue ranges are (count, offset) pairs relating to the txq
array.
This can be done via DCBX negotiation or by kernel.
As a result Enhanced Transmission Selection (ETS) and Priority Flow
Control (PFC) are supported between L2 network traffic classes.
Mapping:
This patch uses the netdev_set_num_tc, netdev_set_prio_tc_map and
netdev_set_tc_queue functions to map priorities to traffic classes
and traffic classes to transmission queue ranges.
This mapping is performed by bnx2x_setup_tc function which is
connected to the ndo_setup_tc.
This function is always called at nic load where by default it
maps all priorities to tc 0, and it may also be called by the
kernel or by the bnx2x upon DCBX negotiation to modify the mapping.
rtnl lock:
When the ndo_setup_tc is called at nic load or by kernel the rtnl
lock is already taken. However, when DCBX negotiation takes place
the lock is not taken. The work is therefore scheduled to be
handled by the sp_rtnl task.
Fastpath:
The fastpath structure of the bnx2x which was previously used
to hold the information of one tx queue and one rx queue was
redesigned to represent multiple tx queues, one for each traffic
class.
The transmission queue supplied in the skb by the kernel can no
longer be interpreted as a straightforward index into the fastpath
structure array, but it must rather be decoded to the appropriate
fastpath index and the tc within that fastpath.
Slowpath:
The bnx2x's queue object was redesigned to accommodate multiple
transmission queues. The queue object's state machine was enhanced
to allow opening multiple transmission-only connections on top of
the regular tx-rx connection.
Firmware:
This feature relies on the tx-only queue feature introduced in the
bnx2x 7.0.23 firmware and the FW likewise must have the bnx2x multi
cos support.

There is no software fallback implemented for SCTP or FCoE checksumming,
and so it should not be passed on by software devices like bridge or bonding.
For VLAN devices, this is different. First, the driver for underlying device
should be prepared to get offloaded packets even when the feature is disabled
(especially if it advertises it in vlan_features). Second, devices under
VLANs do not get replaced without tearing down the VLAN first.
This fixes a mess I accidentally introduced while converting bonding to
ndo_fix_features.
