From 06bab69658a8afb493204448f29703e12e6d3960 Mon Sep 17 00:00:00 2001 From: Dima Chumak Date: Thu, 24 Aug 2023 23:28:35 -0700 Subject: net/mlx5: Implement devlink port function cmds to control ipsec_crypto Implement devlink port function commands to enable / disable IPsec crypto offloads. This is used to control the IPsec capability of the device. When ipsec_crypto is enabled for a VF, it prevents adding IPsec crypto offloads on the PF, because the two cannot be active simultaneously due to HW constraints. Conversely, if there are any active IPsec crypto offloads on the PF, it's not allowed to enable ipsec_crypto on a VF, until PF IPsec offloads are cleared.
