Hi,

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 ]

Thanks

  net/mlx5e: Add SW implementation to support IPsec 64 bit soft and hard
    limits
  net/mlx5e: Overcome slow response for first IPsec ASO WQE
  xfrm: don't require advance ESN callback for packet offload
  net/mlx5e: Remove ESN callbacks if it is not supported
