drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c
The bnx2x gso_type setting bug fix in 'net' conflicted with
changes in 'net-next' that broke the gso_* setting logic
out into a seperate function, which also fixes the bug in
question. Thus, use the 'net-next' version.

The ipv6 route.c conflict is simple, just ignore the 'net' side change
as we fixed the same problem in 'net-next' by eliminating cached
neighbours from ipv6 routes.
The e1000e conflict is an addition of a new statistic in the ethtool

The vmxnet3 conflict is about one change in 'net' removing a guarding
conditional, whilst in 'net-next' we had a netdev_info() conversion.
The iwlwifi conflict is dealing with a WARN_ON() conversion in
'net-next' vs. a revert happening in 'net'.

It is normal for minidrivers accumulating frames to return NULL
from their tx_fixup function. We do not want to count this as a
drop, or log any debug messages. A different exit path is
therefore chosen for such drivers, skipping the debug message
and the tx_dropped increment.
The test for accumulating drivers was however completely bogus,
making the exit path selection depend on whether the user had
enabled tx_err logging or not. This would arbitrarily mess up
accounting for both accumulating and non-accumulating minidrivers,
and would result in unwanted debug messages for the accumulating
drivers.
Fix by testing for FLAG_MULTI_PACKET instead, which probably was
the intention from the beginning. This usage match the documented
behaviour of this flag:
Indicates to usbnet, that USB driver accumulates multiple IP packets.
Affects statistic (counters) and short packet handling.

dm9620 is a newer variant of dm9601 with more features (usb 2.0, checksum
offload, ..), but it can also be put in a dm9601 compatible mode, allowing
us to reuse the existing driver.
This does mean that the extended features like checksum offload cannot be
used, but that's hardly critical on a 100mbps interface.

Reverting 328d7b8 and instead adding an exception for the
Sierra Wireless MC7710.
commit 328d7b8 (net: cdc_mbim: send ZLP after max sized NTBs)
added a workaround for an issue observed on one specific device.
Concerns were raised that this workaround adds a performance
penalty to all devices based on questionable, if not buggy,
behaviour of a single device:
"If you add ZLP for NTBs of dwNtbOutMaxSize, you are heavily affecting CPU
load, increasing interrupt load by factor of 2 in high load traffic
scenario and possibly decreasing throughput for all other devices
which behaves correctly."
"The idea of NCM was to avoid extra ZLPs. If your transfer is exactly
dwNtbOutMaxSize, it's known, you can submit such request on the receiver
side and you do not need any EOT indicatation, so the frametime can be
used for useful data."
Adding a device specific exception to prevent the workaround from
affecting well behaved devices.
The assumption here is that needing a ZLP is truly an *exception*.
We do not yet have enough data to verify this. The generic
workaround in commit 328d7b8 should be considered acceptable despite
the performance penalty if the exception list becomes a maintainance
hassle.

We normally avoid sending ZLPs by padding NTBs with a zero byte
if the NTB is shorter than dwNtbOutMaxSize, resulting in a short
USB packet instead of a ZLP. But in the case where the NTB length
is exactly dwNtbOutMaxSize and this is an exact multiplum of
wMaxPacketSize, then we must send a ZLP.
This fixes an issue seen on a Sierra Wireless MC7710 device
where the transmission would fail whenever we ended up padding
the NTBs to max size.

Adding support for the MBIM mode in some Sierra Wireless devices.
Some Sierra Wireless firmwares support CDC MBIM but have no CDC
Union funtional descriptor. This violates the MBIM specification,
but we can easily work around the bug by looking at the Interface
Association Descriptor instead. This is most likely what
Windows uses too, which explains how the firmware bug has gone
unnoticed until now.
This change will not affect any currently supported device
conforming to the NCM or MBIM specifications, as they must have
the CDC Union descriptor.

The flags argument of the phy_{attach,connect,connect_direct} functions
is then used to assign a struct phy_device dev_flags with its value.
All callers but the tg3 driver pass the flag 0, which results in the
underlying PHY drivers in drivers/net/phy/ not being able to actually
use any of the flags they would set in dev_flags. This patch gets rid of
the flags argument, and passes phydev->dev_flags to the internal PHY
library call phy_attach_direct() such that drivers which actually modify
a phy device dev_flags get the value preserved for use by the underlying
phy driver.

This patch fixes a bug introduced in bbd9f9e which could prevent
some wakeups from working correctly if multiple wol options were
selected.
This helper function calculates a 16-bit crc and shifts it into
either the high or low 16 bits of a u32 so the caller can or it
directly into place. The function previously had a u16 return
type so would always have returned zero when filter was odd.

As pointed out by Bjorn Mork, the generic "usb" driver sets this
for us so no need to directly set it in this driver.

This patch ensures that if we fail to suspend the LAN9500 device
we call usbnet_resume before returning failure, instead of
leaving the usbnet driver in an unusable state.
