Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next
Steffen Klassert says: ==================== pull request (net-next): ipsec-next 2017-08-21 1) Support RX checksum with IPsec crypto offload for esp4/esp6. From Ilan Tayari. 2) Fixup IPv6 checksums when doing IPsec crypto offload. From Yossi Kuperman. 3) Auto load the xfrom offload modules if a user installs a SA that requests IPsec offload. From Ilan Tayari. 4) Clear RX offload informations in xfrm_input to not confuse the TX path with stale offload informations. From Ilan Tayari. 5) Allow IPsec GSO for local sockets if the crypto operation will be offloaded. 6) Support setting of an output mark to the xfrm_state. This mark can be used to to do the tunnel route lookup. From Lorenzo Colitti. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
