Update device capabilities regarding HW filtering multicast loopback support.
Add MLX4_UPDATE_QP_ETH_SRC_CHECK_MC_LB attribute to mlx4_update_qp to
enable changing QP context to support filtering incoming multicast
loopback traffic according the sender's counter index.
Set the corresponding bits in QP context to force the loopback source
checks if attribute is given and HW supports it.

To prevent a race between the TX DMA engine and the CPU the writing of the
first transmit descriptor must be deferred until all following descriptors
have been updated. The network card may otherwise start transmitting before
all packet descriptors are set up correctly, which leads to data corruption
or an aborted transmit operation.
This deferral is already done in the non-TSO TX path, implement it also in
the TSO TX path.

The TX DMA engine requires that buffers with a size of 8 bytes or smaller
must be 64 bit aligned. This requirement may be violated when doing TSO,
as in this case larger skb frags can be broken up and transmitted in small
parts with then inappropriate alignment.
Fix this by checking for proper alignment before handing a buffer to the
DMA engine. If the data is misaligned realign it by copying it into the
TSO header data area.

If a gigabit ethernet PHY is connected to a fast ethernet MAC,
then it can detect 1000 support from the partner but not use it.
This results in a forced speed of 1000 and RX/TX failure.

configuration before setting the MAC speed to 1000mbit.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates 2015-10-19
This series contains updates to i40e and i40evf only.
Kiran adds a spinlock around code accessing VSI MAC filter list to
ensure that we are synchronizing access to the filter list, otherwise
we can end up with multiple accesses at the same time which can cause
the VSI MAC filter list to get in an unstable or corrupted state.
Jesse fixes overlong BIT defines, where the RSS enabling call were
mistakenly missed. Also fixes a bug where the enable function was
enabling the interrupt twice while trying to update the two interrupt
throttle rate thresholds for Rx and Tx, while refactoring the IRQ
enable function to simplify reading the flow. Addressed the high
CPU utilization of some small streaming workloads that the driver should
reduce CPU in.
Anjali fixes two X722 issues with respect to EEPROM checksum verify and
reading NVM version info. Fixed where a mask value was accidentally
replaced with a bit mask causing Flow Director sideband to be broken.
Alex Duyck fixes areas of the drivers which run from hard interrupt
context or with interrupts already disabled in netpoll, so use
napi_schedule_irqoff() instead of napi_schedule().
Mitch fixes the VF drivers to not easily give up when it is not able
to communicate with the PF driver.
Carolyn fixes a problem where our tools MAC loopback test, after driver
unbind would fail because the hardware was configured for multiqueue and
unbind operation did not clear this configuration. Also fixed a issue
where the NVMUpdate tool gets bad data from the PHY when using the PHY
NVM feature because of contention on the MDIO interface from getting
PHY capability calls from the driver during regular operations.
Catherine fixed an issue where we were checking if autoneg was allowed
to change before checking if autoneg was changing, these checks need to
be in the reverse order.
Jean Sacren fixes up an function header comment to align the kernel-docs
with the actual code.
v2: Cleaned up the use of spin_is_locked() in patch 1 based on feedback
from David Miller, since it always evaluates to zero on uni-processor
builds

The dynamic algorithm, while now working, doesn't have good
performance in 40G mode.
One part of this patch addresses the high CPU utilization of some small
streaming workloads that the driver should reduce CPU in.
It also changes the minimum ITR that the dynamic algorithm
will settle on, causing our minimum latency to go from 12us
to about 14us, when using adaptive mode.
It also changes the BULK interrupt rate to allow maximum throughput
on a 40Gb connection with a single thread of transmit, clamping
interrupt rate to 8000 for TX makes single thread traffic go too
slow.
The new ULTRA bulk setting is introduced and is used
when the Rx packet rate on this queue exceeds 40000 packets per
second. This value of 40000 was chosen because the automatic tuning
of minimum ITR=20us means that a single queue can't quite achieve
that many packets per second from a round-robin test.

When the VF driver is unable to communicate with the PF, it just gives
up and never tries again. Aside from the obvious character flaw that
this shows, it's also a lousy user experience.
When PF communications fail, wait five seconds, and try again. And
again. Don't give up, little VF driver! Your prince will come!

This patch introduces a spinlock which is to be used for synchronizing
access to VSI's MAC filter list.
This patch also synchronizes execution of other codepaths which are
accessing VSI's MAC filter list with execution of
service_task:sync_vsi_filters.
In function i40e_add_vsi, copied out LAA MAC address instead of cloning
MAC filter entry because only MAC address is needed to remove MAC VLAN
filter from FW/HW.

Link interrupts are enabled in init_umac(), which is too early for us to
process them since we do not yet have a valid PHY device pointer. On
BCM7425 chips for instance, we will crash calling phy_mac_interrupt()
because phydev is NULL.
Fix this by moving the link interrupts enabling in
bcmgenet_netif_start(), under a specific function:
bcmgenet_link_intr_enable() and while at it, update the comments
surrounding the code.
