Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 

Conflicts:
	drivers/net/phy/amd-xgbe-phy.c
	drivers/net/wireless/iwlwifi/Kconfig
	include/net/mac80211.h

iwlwifi/Kconfig and mac80211.h were both trivial overlapping
changes.

The drivers/net/phy/amd-xgbe-phy.c file got removed in 'net-next' and
the bug fix that happened on the 'net' side is already integrated
into the rest of the amd-xgbe driver.

Command filtering and pass_level
--------------------------------
TCMU supports a "pass_level" option with valid values of 0 or 1. When
the value is 0 (the default), nearly all SCSI commands received for
the device are passed through to the handler. This allows maximum
flexibility but increases the amount of code required by the handler,
to support all mandatory SCSI commands. If pass_level is set to 1,
then only IO-related commands are presented, and the rest are handled
by LIO's in-kernel command emulation. The commands presented at level
1 include all versions of:
READ
WRITE
WRITE_VERIFY
XDWRITEREAD
WRITE_SAME
COMPARE_AND_WRITE
SYNCHRONIZE_CACHE
UNMAP
A final note
