From 6764b1fccccb7b3f14a2714279cdcf410313fa83 Mon Sep 17 00:00:00 2001 From: Vu Pham Date: Thu, 12 Mar 2020 10:26:25 -0700 Subject: [PATCH] net/mlx5e: Use change upper event to setup representors' bond_metadata Use change upper event to detect slave representor from enslaving/unslaving to/from lag device. On enslaving event, call mlx5_enslave_rep() API to create, add this slave representor shadow entry to the slaves list of bond_metadata structure representing master lag device and use its metadata to setup ingress acl metadata header. On unslaving event, resetting the vport of unslaved representor to use its default ingress/egress acls and rx rules with its default_metadata. The last slave will free the shared bond_metadata and its unique metadata.
