Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates

This series contains updates to e1000e, ixgbevf and igb.

Majority of this series contains fixes and cleanups to e1000e,
most notably are:

Todd provides a fix to PTP in e1000e which adds a lock in e1000e_phc_adjfreq
to prevent concurrent changes to TIMINCA and SYSTIMH/L. Then provides an
igb fix to use ARRAY_SIZE for array size calculation.

David provides the remaining e1000e which contain:
- cleanup of pointer references that are no longer used
- fix an issue on systems with Management Engine enabled with the
ethernet cable unplugged
- fix an issue on 82579 where enabling EEE LPI sooner than one second
after link up causes link issues on some switches
- refactor the power management flows to prevent the suspend path from
being executed twice when hibernating
- refactor the runtime power management to fix interfering with the
functionality of Energy Efficient Ethernet when enabled and to fix
the device from repeatedly flip between suspend and resume with the
interface administratively downed
- enable the feature PHY Ultra Low Power Mode which is a power saving
feature that reduces the power consumption of the PHY when a cable is
not connected
- fix the ethtool offline tests for 82579 parts
- fix SHRA register access for 82579 parts which was introduced by
previous commit c3a0dce35af0 "e1000e: fix overrun of PHY RAR array"

Florian provides a fix for ixgbevf where skb->pkt_type was being checked
like a bitmask, but it is not a bitmask.

Fix an issue reported by Stephen Hemminger where there was a warning
about code defined but never used if IGB_HWMON is not defined.
