From 02b34d03a24b18970925cf57434be28ba4a29d3a Mon Sep 17 00:00:00 2001 From: Sabrina Dubroca Date: Thu, 13 Jul 2023 15:20:23 +0200 Subject: netdevsim: add dummy macsec offload When the kernel is compiled with MACsec support, add the NETIF_F_HW_MACSEC feature to netdevsim devices and implement macsec_ops. To allow easy testing of failure from the device, support is limited to 3 SecY's per netdevsim device, and 1 RXSC per SecY. v2: - nsim_macsec_add_secy, return -ENOSPC if secy_count isn't full but we can't find an empty slot (Simon Horman) - add sci_to_cpu to make sparse happy (Simon Horman) - remove set but not used secy variable (kernel test robot and Simon Horman) Signed-off-by: Sabrina Dubroca Reviewed-by: Simon Horman Signed-off-by: David S.
