Francois Romieu 78f1cd0245 r8169: fix broken register writes
This is quite similar to b39fe41f48
though said registers are not even documented as 64-bit registers
- as opposed to the initial TxDescStartAddress ones - but as single
bytes which must be combined into 32 bits at the MMIO read/write
level before being merged into a 64 bit logical entity.

Credits go to Ben Hutchings <ben@decadent.org.uk> for the MAR
registers (aka "multicast is broken for ages on ARM) and to
Timo Teräs <timo.teras@iki.fi> for the MAC registers.

Andy Gospodarek a2fd940f4c bonding: fix broken multicast with round-robin mode
Round-robin (mode 0) does nothing to ensure that any multicast traffic
originally destined for the host will continue to arrive at the host when
the link that sent the IGMP join or membership report goes down.  One of
the benefits of absolute round-robin transmit.

Keeping track of subscribed multicast groups for each slave did not seem
like a good use of resources, so I decided to simply send on the
curr_active slave of the bond (typically the first enslaved device that
is up).  This makes failover management simple as IGMP membership
reports only need to be sent when the curr_active_slave changes.  I
tested this patch and it appears to work as expected.

Emil Tantilov 39ca5f033b e1000: do not modify tx_queue_len on link speed change
Previously the driver tweaked txqueuelen to avoid false Tx hang reports
seen at half duplex.  This had the effect of overriding user set values
on link change/reset. Testing shows that adjusting only the timeout
factor is sufficient to prevent Tx hang reports at half duplex.

This patch removes all instances of tx_queue_len in the driver.

Greg Rose e7d481a6f3 ixgbe: Do not run all Diagnostic offline tests when VFs are active
When running the offline diagnostic tests check to see if any VFs are
online.  If so then only run the link test.  This is necessary because
the VFs running in guest VMs aren't aware of when the PF is taken
offline for a diagnostic test.  Also put a message to the system log
telling the system administrator to take the VFs offline manually if
(s)he wants to run a full diagnostic.  Return 1 on each of the tests

Alexander Duyck 03e6d819c2 skbuff: remove unused dma_head & dma_maps fields
The dma map fields in the skb_shared_info structure no longer has any users
and can be dropped since it is making the skb_shared_info unecessarily larger.

Running slabtop show that we were using 4K slabs for the skb->head on x86_64 w/
an allocation size of 1522.  It turns out that the dma_head and dma_maps array
made skb_shared large enough that we had crossed over the 2k boundary with
standard frames and as such we were using 4k blocks of memory for all skbs.

Vasu Dev f6b9f4b263 vlan: updates vlan real_num_tx_queues
Updates real_num_tx_queues in case underlying real device
has changed real_num_tx_queues.

-v2
 As per Eric Dumazet<eric.dumazet@gmail.com> comment:-
   -- adds BUG_ON to catch case of real_num_tx_queues exceeding num_tx_queues.
   -- created this self contained patch to just update real_num_tx_queues.

Vasu Dev 669d3e0bab vlan: adds vlan_dev_select_queue
This is required to correctly select vlan tx queue for a driver
supporting multi tx queue with ndo_select_queue implemented since
currently selected vlan tx queue is unaligned to selected queue by
real net_devce ndo_select_queue.

Unaligned vlan tx queue selection causes thrash with higher vlan
tx lock contention for least fcoe traffic and wrong socket tx
queue_mapping for ixgbe having ndo_select_queue implemented.

-v2

As per Eric Dumazet<eric.dumazet@gmail.com> comments, mirrored
vlan net_device_ops to have them with and without vlan_dev_select_queue
and then select according to real dev ndo_select_queue present or not
for a vlan net_device. This is to completely skip vlan_dev_select_queue
calling for real net_device not supporting ndo_select_queue.

Alexander Duyck 31b24b955c igb: only use vlan_gro_receive if vlans are registered
This change makes it so that vlan_gro_receive is only used if vlans have been
registered to the adapter structure.  Previously we were just sending all vlan
tagged frames in via this function but this results in a null pointer
dereference when vlans are not registered.

[ This fixes bugzilla entry 15582 -Eric Dumazet]

Emil Tantilov d07f3e375f igb: do not modify tx_queue_len on link speed change
Previously the driver tweaked txqueuelen to avoid false Tx hang reports seen at half duplex.
This had the effect of overriding user set values on link change/reset. Testing shows that
adjusting only the timeout factor is sufficient to prevent Tx hang reports at half duplex.

Mitch Williams fa3d9a6d55 igb: count Rx FIFO errors correctly
Don't aggregate rx_no_buffer_count into rx_fifo_errors. RNBC counts
packets that get queued temporarily in the adapter's FIFO. These
packets are not dropped and are not errors. The correct counter
is rx_missed_errors (MPC).
