Padmanabh Ratnakar 1578e7778f be2net: Fix driver load for VFs for Lancer
Permanent MAC is wrongly supplied in create iface command. Call the
command with no MAC address and then MAC address should be later queried
and applied.

o Use correct l3 (ETH_IP or ETH_IPV6)protcol in case

was setting incorrect opcode. This resulted in adapter calculating

Rajesh Borundia cae82d4999 qlcnic: Fix estimation of recv MSS in case of LRO
o Linux stack estimates MSS from skb->len or skb_shinfo(skb)->gso_size.
In case of LRO skb->len is aggregate of len of number of packets hence MSS
obtained using skb->len would be incorrect. Incorrect estimation of recv MSS
would lead to delayed acks in some traffic patterns (which sends two or three
packets and wait for ack and only then send remaining packets). This leads to
drop in performance. Hence we need to set gso_size to MSS obtained from firmware.

o This is fixed recently in firmware hence the MSS is obtained based on
capability. If fw is capable of sending the MSS then only driver sets the gso_size.

AnilKumar Ch 69927fccd9 can: c_can: Add support for Bosch D_CAN controller
This patch adds the support for D_CAN controller driver to the existing
C_CAN driver.

Bosch D_CAN controller is a full-CAN implementation which is compliant
to CAN protocol version 2.0 part A and B. Bosch D_CAN user manual can be
obtained from: http://www.semiconductors.bosch.de/media/en/pdf/
ipmodules_1/can/d_can_users_manual_111.pdf

A new array is added for accessing the d_can registers, according to d_can
controller register space.

Current D_CAN implementation has following limitations, this is done
to avoid large changes to the C_CAN driver.
1. Message objects are limited to 32, 16 for RX and 16 for TX. C_CAN IP
   supports upto 32 message objects but in case of D_CAN we can configure
   upto 128 message objects.
2. Using two 16bit reads/writes for accessing the 32bit D_CAN registers.
3. These patches have been tested on little endian machine, there might
   be some hidden endian-related issues due to the nature of the accesses
   (32-bit registers accessed as 2 16-bit registers). However, I do not
   have a big-endian D_CAN implementation to confirm.

AnilKumar Ch 33f8100977 can: c_can: Move overlay structure to array with offset as index
c_can uses overlay structure for accessing c_can module registers.
With this kind of implementation it is difficult to add one more ip
which is similar to c_can in functionality but different register
offsets.

This patch changes the overlay structure implementation to an array
with register offset as index. This way we can overcome the above
limitation.

pci and the platform code mutually exclusive.
Having both could also help, at built time ,to verify that
all the code is validated and compiles fine.

Sathya Perla 0513ac3d22 be2net: do not modify PCI MaxReadReq size
Setting the PCI MRRS to a value of 4096 (overriding the system decided
value) had provided perf improvement in TX.
But, IBM has provided feedback that on POWER platforms, this value is set
by the system firmware, and drivers modifying this value can cause
unpredictable results (like EEH errors.) So, backing off this change.
On POWER7 platforms most slots, it seems, do get a MRRS of 4096.

This patch reverts the following commit:
"be2net: Modified PCI MaxReadReq size to 4096 bytes"

John Fastabend 43e95f11ac ixgbe: IXGBE_RXD_STAT_VP set even with Rx stripping enabled
The hardware bit IXGBE_RXD_STAT_VP appears to be set even when Rx
stripping is disabled. This results in passing frames up the stack
which do not have the 802.1Q tag stripped but have the tci bits
set as if it was.

Working around this with a check for the feature flag bit. I
would welcome any better ideas or a pointer to exactly which
bits in the hardware register need to be cleared to get the
IXGBE_RXD_STAT_VP bit to be set per data sheet.

Linus reported that due to mac80211 failing to register
the device (due to WoWLAN) his machine crashed etc. as
we double-freed the vmalloc() firmware area. His patch
to fix it was very similar to this one but I noticed
that there's another bug in the area: we complete the
completion before starting, so since we're running in
a work struct context stop() could be called while in
the middle of start() which will almost certainly lead
to issues.

Make a modification similar to his to avoid the double-
free but also move the completion to another spot so it
is only done after start() either finished or failed so
that stop() can have a consistent state.

Johannes Berg a5fdde28b4 iwlwifi: fix TX power antenna access
Since my commit
  iwlwifi: use valid TX/RX antenna from hw_params
the config values are pure overrides, not the
real values for all hardware. Therefore, the
EEPROM TX power reading code checks the wrong
values, it should check the hw_params values.

Giuseppe CAVALLARO 13497f5867 stmmac: remove two useless initialisations
This patch removes two useless initialisations in the
stmmac_rx and stmmac_tx functions.
In the former, the count variable was reset twice and in
the stmmac_tx we only need to increment the dirty pointer
w/o setting the entry variable.

v2: review the subject and comment that was not clear in my
first version.

This is done by setting the "INTR pin used" bit and cleaning

AnilKumar Ch f461f27a44 can: c_can: fix race condition in c_can_open()
Fix the issue of C_CAN interrupts getting disabled forever when canconfig
utility is used multiple times. According to NAPI usage we disable all
the hardware interrupts in ISR and re-enable them in poll(). Current
implementation calls napi_enable() after hardware interrupts are enabled.
If we get any interrupts between these two steps then we do not process
those interrupts because napi is not enabled. Mostly these interrupts
come because of STATUS is not 0x7 or ERROR interrupts. If napi_enable()
happens before HW interrupts enabled then c_can_poll() function will be
called eventual re-enabling.

This patch moves the napi_enable() call before interrupts enabled.
