If anyone has any objections, please let me know. ------------------ From: Leon Romanovsky [ Upstream commit 482db2f1dd211f73ad9d71e33ae15c1df6379982 ] XFRM state doesn't need anything from flags except to understand direction, so store it separately. For future patches, such change will allow us to reuse xfrm_dev_offload for policy offload too, which has three possible directions instead of two.
