Subject: [patch net-next v2 09/10] mlxsw: spectrum_acl: Implement TC block sharing
From: Jiri Pirko <jiri@...lanox.com>
Benefit from the prepared TC and in-driver ACL infrastructure and
introduce block sharing offload. For that, a new struct "block" is
introduced in spectrum_acl in order to hold a list of specific
block-port bindings.
