ATM, txq_reclaim will dequeue and free an skb for each tx desc released
by the hw that has TX_LAST_DESC set. However, in case of TSO, each
hw desc embedding the last part of a segment has TX_LAST_DESC set,
losing the one-to-one 'last skb frag'/'TX_LAST_DESC set' correspondance,
which causes data corruption.
Fix this by checking TX_ENABLE_INTERRUPT instead of TX_LAST_DESC, and
warn when trying to dequeue from an empty txq (which can be symptomatic
of releasing skbs prematurely).

This patch aims to fix the concurrency in eee initialization
inside the stmmac driver and related warnings when enable
DEBUG_ATOMIC_SLEEP.
Prior this patch, the stmmac_eee_init could be called in several places
as shown below:
stmmac_open stmmac_resume PHY Layer
| | |
stmmac_hw_setup stmmac_adjust_link
| | stmmac ethtool
|__________________________|______________|
|
stmmac_eee_init
The patch removes the stmmac_eee_init call inside the stmmac_hw_setup
that is unnecessary. It is sufficient to call it in the adjust_link to
always guarantee that EEE is always configured at mac level too.
Fixing the lock protection now it is covered another case (not
considered before). The stmmac_eee_init could be called by the ethtool
so critical sections must be protected inside this function too.

Microblaze is a fpga soft core, it can be customized easily, which may
cause many various hardware version strings.
So the original fix patch based on hard-coded compatible version strings
is not a good idea (although it is correct for current issue). For it,
there will be a new solving way soon (which based on the device tree).
The original issue is related with qemu, so can only change the hardware
version string in qemu for it, then keep the original driver no touch (
qemu is for virtualization which has much easier life than real world).

====================
Intel Wired LAN Driver Updates 2014-11-03
This series contains updates to i40e and i40evf.
Akeem adds a check for i40e so that flow director flush and reinit are
not done when flow director is not enabled.
Mitch fixes the i40evf driver to properly handle multiple admin queue
messages, by reinit the msg_size field each time we go through the loop.
Without this, we may receive truncated messages due to the firmware
thinking we have insufficient buffer size. Also fixes the link checking
logic to only check the carrier state if the interface is actually
open, which allows link changes to be reported correctly without spamming
the VFs. Updates i40e to inset the VSI ID in the QTX_CTL register
when configuring queues for VMDq VSIs.
Paul adds support for 10G-base-T in i40evf.
Jesse fixes i40e where the call to irq_dynamic_disable() was turning off
the interrupt completely when trying to set ITR to 0 (for lowest
moderation).
Shannon removes debugfs dump stats function, since it was not being
kept up-to-date and was redundant with the ethtool output. Also, scales
back the LAN MSIx usage to force queue/vector sharing and leave some
vectors for Flow Director, VMDq, etc. when there are more cores than
vectors available to the PF. Cleans up the error reporting for
get_lump() resource tracking errors. Also adds a check for the
debug module parameter earlier to be able to catch the early configuration
phase admin queue messages.

When IP_ALIGN has a non zero value, hardware will write to a non aligned
address. The only reader from this address is when copying the header
from the first frag into the linear buffer (further access to the IP
address will be from the linear buffer, in which the headers are
