[Intel-wired-lan] [PATCH next-queue 5/8] ixgbe: add VF IPsec offload request message handling
Shannon Nelson

Mon Aug 13 18:43:42 UTC 2018
Add an add and a delete message for IPsec offload requests from
the VF. These call into the ipsec functions that can translate
the message buffer into a useful IPsec offload.
These new messages bump the mbox API version to 1.4.
