- Port speed settings are applied by the device only upon
port admin status transition from DOWN to UP.
So we enforce this transition regardless of the port's
current operation state (which may be occasionally DOWN if
for example the network cable is disconnected).
- Fix the PORT_UP/DOWN device interface enum
- Set the local_port bit in the device PAOS register
- EXPORT the PAOS (Port Administrative and Operational Status)

devcmd is an interface for driver to communicate with fw/adaptor. It
involves writing data to hardware registers and waiting for the result.
This mechanism does not scale well. The queuing of "no wait" devcmds is
done in firmware memory rather than on the host. Firmware memory is a
rather more scarce and valuable resource than host memory. A devcmd storm
from one vf can disrupt the service on other pf/vf. The lack of flow
control allows for possible denial of server from one VM to another.
Devcmd2 uses work queue to post the devcmds, just like tx work queue. This
allows better flow control.
Initialize devcmd2, if fails we fall back to devcmd1.
Also change the driver version.

VxLAN offloading is not functional if the NIC is running in multichannel
mode (UMC, FLEX-10, VNIC...). Enabling this additionally kills whole
connectivity through the NIC and the device needs to be down and up to
restore it. The firmware should take care about it and does not allow
the conversion of interface to tunnel type (be_cmd_manage_iface) or should
support VxLAN offloading if multichannel config is enabled.
I have tested this on the latest available firmware (10.6.144.21).

Commit 0b50dc4fc9 ("Convert smsc911x to use ACPI as well as DT") makes
the call to smsc911x_probe_config() unconditional, and no longer fails if
there is no device node. device_get_phy_mode() is called unconditionally,
and if there is no phy node configured returns an error code. This error
code is assigned to phy_interface, and interpreted elsewhere in the code
as valid phy mode. This in turn causes qemu to crash when running a
variant of realview_pb_defconfig.

PPP devices may get automatically unregistered when their network
namespace is getting removed. This happens if the ppp control plane
daemon (e.g. pppd) exits while it is the last user of this namespace.
This leads to several races:
* ppp_exit_net() may destroy the per namespace idr (pn->units_idr)
before all file descriptors were released. Successive ppp_release()
calls may then cleanup PPP devices with ppp_shutdown_interface() and
try to use the already destroyed idr.
* Automatic device unregistration may also happen before the
ppp_release() call for that device gets executed. Once called on
the file owning the device, ppp_release() will then clean it up and
try to unregister it a second time.
To fix these issues, operations defined in ppp_shutdown_interface() are
moved to the PPP device's ndo_uninit() callback. This allows PPP
devices to be properly cleaned up by unregister_netdev() and friends.
So checking for ppp->owner is now an accurate test to decide if a PPP
device should be unregistered.
Setting ppp->owner is done in ppp_create_interface(), before device
registration, in order to avoid unprotected modification of this field.
Finally, ppp_exit_net() now starts by unregistering all remaining PPP
devices to ensure that none will get unregistered after the call to
idr_destroy().

Management firmware tells driver in case bandwidth configuration for
a specific function exists, but [regretably] the same field has different
meanings depending on the multi-function mode - it can either be
a percentile value or an actual speed.
For newer multi-function modes current logic is incorrect -
driver understands values as actual speeds instead of percentages,
causing the resulting chip configuration to be incorrect.

This driver borrows heavily from IPvlan and teaming drivers.
Routing domains (VRF-lite) are created by instantiating a VRF master
device with an associated table and enslaving all routed interfaces that
participate in the domain. As part of the enslavement, all connected
routes for the enslaved devices are moved to the table associated with
the VRF device. Outgoing sockets must bind to the VRF device to function.
Standard FIB rules bind the VRF device to tables and regular fib rule
processing is followed. Routed traffic through the box, is forwarded by
using the VRF device as the IIF and following the IIF rule to a table
that is mated with the VRF.
Example:
Create vrf 1:
ip link add vrf1 type vrf table 5
ip rule add iif vrf1 table 5
ip rule add oif vrf1 table 5
ip route add table 5 prohibit default
ip link set vrf1 up
Add interface to vrf 1:
ip link set eth1 master vrf1

There are some MAC registers that need to be kept in sync
with the link state parameters, see adjust_link().
However, after a MAC soft reset default values for
these registers are assumed. In some cases (excepting
if down/ if up for example) adjust_link() does not see
that these values were reset to default because the
priv->old* link parameters were left unchanged.
So, reset the priv->old* link params as well during a
MAC reset to let adjust_link() restore the MAC link
settings to the actual link state values.
Fixes following case, for example:
Setting link to 100M, changing MTU (implies MAC reset),
link state remains unchanged to 100M but MAC registers
were reset to default (1G) breaking the connectivity w/
the PHY. Closing and re-opening the interface would
restore the MAC link parameters to the correct values.

Rocker driver tracks arp_tbl neighs to resolve IPv4 route nexthops. The
driver uses NETEVENT_NEIGH_UPDATE for neigh adds and updates, but there is
no event when the neigh is removed from the device (such as when the device
goes admin down). This patches hooks ndo_neigh_destroy so the driver can
know when a neigh is removed from the device. In response, the driver will
purge the neigh entry from its internal tbl.
I didn't find an in-tree users of ndo_neigh_destroy, so I'm not sure if
this ndo is vestigial or if there are out-of-tree users. In any case, it
does what I need here. An alternative design would be to generate
NETEVENT_NEIGH_UPDATE event when neigh is being destroyed, setting state to
NUD_NONE so driver knows neigh entry is dead.

As per Am335x Errata [1] Advisory 1.0.9, The CPSW C0_TX_PEND and
C0_RX_PEND interrupt outputs provide a single transmit interrupt
that combines transmit channel interrupts TXPEND[7:0] and a
single receive interrupt that combines receive channel interrupts
RXPEND[7:0]. The TXPEND[0] and RXPEND[0] interrupt outputs are
connected to the ARM Cortex-A8 interrupt controller (INTC) rather
than the C0_TX_PEND and C0_RX_PEND interrupt outputs. So even
though CPSW interrupt is cleared by writing appropriate values to
EOI register the interrupt is not cleared in IRQ controller. So
interrupt is still pending and CPU is struck in ISR, the
workaround is to disable the interrupts in ARM irq controller.

Even though there's a WMI enum for fragmentation
threshold no known firmware actually implements
it. Moreover it is not possible to rely frame
fragmentation to mac80211 because firmware clears
the "more fragments" bit in frame control making
it impossible for remote devices to reassemble
frames.
Hence implement a dummy callback just to say
fragmentation isn't supported. This effectively
prevents mac80211 from doing frame fragmentation
in software.
This fixes Tx becoming broken after setting
fragmentation threshold.

(Entire cluster gets AND-ed together).
(3) We observed that the masking rules it generates do not
play well with clustering on P2020. Only first rule
of the cluster would ever fire. Given that optimizer
relies heavily on masking this is very hard to fix.

ff: MASK >= 00000000 Q:00 ctrl:00000020 prop:00000000
Which looks correct according to the spec but only the first
(eth id 252)/last added rule for 10.0.0.3 will ever trigger.
As if filer did not treat the AND CLE as cluster start but
also kept AND-ing the rules. We found no errata covering this.
The fact that nobody noticed (2) or (3) makes me think
that this feature is not very widely used and we should just
remove it.

The packet gets dropped in qdisc (noop_enqueue).
The fix is to delay the sending of gratuitous ARPs till the bond dev's
carrier is present.
It can also be worked around by setting num_grat_arp to more than 1.

When we transmit a fragmented skb, we may run into a race like the

cpu 0 cpu 1
fec_enet_txq_submit_skb
reserve a bdp for the first fragment
fec_enet_txq_submit_frag_skb
update the bdp for the other fragment
update txq->cur_tx
fec_enet_tx_queue
bdp = fec_enet_get_nextdesc(txq->dirty_tx, fep, queue_id);
This bdp is the bdp reserved for the first segment. Given
that this bdp BD_ENET_TX_READY bit is not set and txq->cur_tx
is already pointed to a bdp beyond this one. We think this is a
completed bdp and try to reclaim it.
update the bdp for the first segment
update txq->cur_tx
So we shouldn't update the txq->cur_tx until all the update to the
bdps used for fragments are performed. Also add the corresponding
memory barrier to guarantee that the update to the bdps, dirty_tx and
cur_tx performed in the proper order.

When starting a p2p mgmt interface, enable its device role. This

In general, p2p management interfaces cannot send vif-specific commands
to FW, as the vif role id is invalid. Only off-channel data and scans
happen on this vif, so most ops are not relevant.
If the vif is a p2p mgmt vif, block some mac80211 ops.
Configure rate policies for p2p mgmt interface, as
otherwise p2p packets come out with arbitrary rates.
Since wpa_supplicant currently doesn't support standalone
p2p device mode (without another attached managed interface),
add p2p device to the allowed interface combinations without
decreasing the allowed station count.
Moreover, increase the station count in some cases, as AP
mode usually starts as station interface, and the AP interface

The PP2 controller is capable of per-CPU TX processing, which means there are
per-CPU banked register sets and queues. Current version of the driver supports
TX packet coalescing - once on given CPU sent packets amount reaches a threshold
value, an IRQ occurs. However, there is a single interrupt line responsible for
CPU0/1 TX and RX events (the latter is not per-CPU, the hardware does not
support RSS).
When the top-half executes the interrupt cause is not known. This is why in
NAPI poll function, along with RX processing, IRQ cause register on both
CPU's is accessed in order to determine on which of them the TX coalescing
threshold might have been reached. Thus the egress processing and releasing the
buffers is able to take place on the corresponding CPU. Hitherto approach lead
to an illegal usage of on_each_cpu function in softirq context.
The problem is solved by resigning from TX coalescing interrupts and separating
egress finalization from NAPI processing. For that purpose a method of using
hrtimer is introduced. In main transmit function (mvpp2_tx) buffers are released
once a software coalescing threshold is reached. In case not all the data is
processed a timer is set on this CPU - in its interrupt context a tasklet is
scheduled in which all queues are processed. At once only one timer per-CPU can
be running, which is controlled by a dedicated flag.
This commit removes TX processing from NAPI polling function, disables hardware
coalescing and enables hrtimer with tasklet, using new per-CPU port structure
(mvpp2_port_pcpu).

mvpp2 driver allows usage of per-CPU TX processing. Once the packets are
prepared independetly on each CPU, the hardware enqueues the descriptors in
common TX queue. After they are sent, the buffers and associated sk_buffs
should be released on the corresponding CPU.
This is why a special index is maintained in order to point to the right data to
be released after transmission takes place. Each per-CPU TX queue comprise an
array of sent sk_buffs, freed in mvpp2_txq_bufs_free function. However, the
index was used there also for obtaining a descriptor (and therefore a buffer to
be DMA-unmapped) from common TX queue, which was wrong, because it was not
referring to the current CPU.
This commit enables proper unmapping of sent data buffers by indexing them in
per-CPU queues using a dedicated array for keeping their physical addresses.
