A change in MCFW behaviour means that the net driver must update its record
of the warm_boot_count by reading it from the ER_DZ_BIU_MC_SFT_STATUS
register.
On v4.6.x MCFW the global boot count was incremented when some functions
needed to be reset to enable multicast chaining, so all functions saw the
same value. In that case, the driver needed to increment its
warm_boot_count when other functions were reset, to avoid noticing it later
and then trying to reset itself to recover unnecessarily.
With v4.7+ MCFW, the boot count in firmware doesn't change as that is
unnecessary since the PFs that have been reset will each receive an MC
reboot notification. In that case, the driver re-reads the unchanged
value.

There is a memleak when suspend/resume this driver version.
Currently the stmmac, during resume step, reallocates all the resources
but they are not released when suspend.
The patch is not to release these resources but the logic has been changed.
In fact, it is not necessary to free and reallocate all from scratch
because the memory data will be always preserved.
As final solution, the patch just reinit the descriptors and the rx/tx
pointers only when resume. Tested done on STi boxes.

Intel Wired LAN Driver Updates 2015-12-03
This series contains updates to ixgbe, i40e/i40evf, MAINTAINERS and e100.txt
Alex provides a fix for ixgbe where enabling SR-IOV and then bringing the
interface up was resulting in the PF MAC addresses getting into a bad state.
The workaround for this issue is to bring up the interface first and then
enable SR-IOV as this will trigger the reset in the existing code.
I clean up legacy license stuff in the e100.txt documentation and then
update the maintainers/reviewers list for our drivers.
Jesse fixes an issue with the i40e/i40evf drivers, where if the driver were
to happen to have a mutex held while the i40e_init_adminq() call was called,
the init_adminq might inadvertently call mutex_init on a lock that was held
which is a violation of the calling semantices.

MPX decodes instructions in order to tell which bounds register
was violated. Part of this decoding involves looking at the "REX
prefix" which is a special instrucion prefix used to retrofit
support for new registers in to old instructions.
The X86_REX_*() macros are defined to return actual bit values:
#define X86_REX_R(rex) ((rex) & 4)
*not* boolean values. However, the MPX code was checking for
them like they were booleans. This might have led to us
mis-decoding the "REX prefix" and giving false information out to
userspace about bounds violations. X86_REX_B() actually is bit 1,
so this is really only broken for the X86_REX_X() case.
Fix the conditionals up to tolerate the non-boolean values.

The SPI tx and rx buffers are both supposed to be scan_bytes amount of
bytes large and a common allocation is used to allocate both buffers. This

The initialization of the tx buffer pointer is done adding scan_bytes to
the beginning of the rx buffer, but since the rx buffer is of type __be16
this will actually add two times as much and the tx buffer ends up pointing
after the allocated buffer.
Fix this by using scan_count, which is scan_bytes / 2, instead of
scan_bytes when initializing the tx buffer pointer.

The tegra-apb DMA driver enables runtime-pm but never calls

Fix this by replacing the clk_prepare_enable() and clk_disable_unprepare()
with pm_runtime_get_sync() and pm_runtime_put(), respectively. Note that
the consequence of this is that if runtime-pm is disabled, then the clocks
will remain on the entire time the driver is loaded. However, if
runtime-pm is disabled, then power is not most likely not a concern.
