Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue
Jeff Kirsher says:
====================
Intel Wired LAN Driver Fixes 2019-11-08
This series contains fixes to igb, igc, ixgbe, i40e, iavf and ice
drivers.
Colin Ian King fixes a potentially wrap-around counter in a for-loop.
Nick fixes the default ITR values for the iavf driver to 50 usecs
interval.
Arkadiusz fixes 'ethtool -m' for X722 devices where the correct value
cannot be obtained from the firmware, so add X722 to the check to ensure
the wrong value is not returned.
Jake fixes igb and igc drivers in their implementation of launch time
support by declaring skb->tstamp value as ktime_t instead of s64.
Magnus fixes ixgbe and i40e where the need_wakeup flag for transmit may
not be set for AF_XDP sockets that are only used to send packets.
