Jeff Kirsher says:

====================
1GbE Intel Wired LAN Driver Updates 2018-01-24

This series contains updates to igb and e1000e only.

Corinna Vinschen implements the ability to set the VF MAC to
00:00:00:00:00:00 via RTM_SETLINK on the PF, to prevent receiving
"invlaid argument" when libvirt attempts to restore the MAC address back
to its original state of 00:00:00:00:00:00.

Zhang Shengju adds a new function igb_get_max_rss_queues() to get the
maxium number of RSS queues and to reduce code duplication.

Matt fixes an issue with e1000e where when setting HTHREST, we should
only be setting bit 8.  Also added a dev_info() message to alert when
C-states have been disabled, to help in debugging.

Jesus adds code comments to clarify the idlescope configuration
constraints.

Lyude Paul fixes a kernel crash on hotplug of igb, by checking to ensure
that we are in the process of dismantling the netdev on hotplug events.

Markus Elfring removes a duplicate message for a memory allocation
failure.

Daniel Hua fixes an issue where transmit timestamps will stop being put
into the socket when link is repeatedly up/down due to TSYNCTXCTL's TXTT
bit (Transmit timestamp valid bit) not clearing in the timeout logic of
ptp_tx_work(), which in turn causes no new timestamp to be loaded to the
TXSTMP register.
