From b691b1116e820450de8a5d50eb4ce546a7de93dc Mon Sep 17 00:00:00 2001 From: Dima Chumak Date: Thu, 24 Aug 2023 23:28:36 -0700 Subject: net/mlx5: Implement devlink port function cmds to control ipsec_packet Implement devlink port function commands to enable / disable IPsec packet offloads. This is used to control the IPsec capability of the device. When ipsec_offload is enabled for a VF, it prevents adding IPsec packet offloads on the PF, because the two cannot be active simultaneously due to HW constraints. Conversely, if there are any active IPsec packet offloads on the PF, it's not allowed to enable ipsec_packet on a VF, until PF IPsec offloads are cleared.
