[GIT PULL] Improve IPsec limits, ESN and replay window

[GIT PULL] Improve IPsec limits, ESN and replay window

[Leon Romanovsky]

This series overcomes existing hardware limitations in Mellanox ConnectX
devices around handling IPsec soft and hard limits.

In addition, the ESN logic is tied and added an interface to configure
replay window sequence numbers through existing iproute2 interface.

  ip xfrm state ... [ replay-seq SEQ ] [ replay-oseq SEQ ]
                    [ replay-seq-hi SEQ ] [ replay-oseq-hi SEQ ]
