Merge branch '10GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue

Jeff Kirsher says:

====================
10GbE Intel Wired LAN Driver Updates 2018-01-23

This series contains updates to ixgbe only.

Shannon Nelson provides an implementation of the ipsec hardware offload
feature for the ixgbe driver for these devices: x540, x550, 82599.

The ixgbe NICs support ipsec offload for 1024 Rx and 1024 Tx Security
Associations (SAs), using up to 128 inbound IP addresses, and using the
rfc4106(gcm(aes)) encryption.  This code does not yet support checksum
offload, or TSO in conjunction with the ipsec offload - those will be
added in the future.

This code shows improvements in both packet throughput and CPU utilization.
For example, here are some quicky numbers that show the magnitude of the
performance gain on a single run of "iperf -c <dest>" with the ipsec
offload on both ends of a point-to-point connection:

	9.4 Gbps - normal case
	7.6 Gbps - ipsec with offload
	343 Mbps - ipsec no offload
