Message-Id: <20230522090542.45679-7-wojciech.drewek@intel.com> Date: Mon, 22 May 2023 11:05:38 +0200 From: Wojciech Drewek <wojciech.drewek@...el.com> To: intel-wired-lan@...ts.osuosl.org Cc: netdev@...r.kernel.org, alexandr.lobakin@...el.com, david.m.ertman@...el.com, michal.swiatkowski@...ux.intel.com, marcin.szycik@...ux.intel.com, pawel.chmielewski@...el.com, sridhar.samudrala@...el.com Subject: [PATCH iwl-next v3 06/10] ice: Accept LAG netdevs in bridge offloads Allow LAG interfaces to be used in bridge offload using netif_is_lag_master. In this case, search for ice netdev in the list of LAG's lower devices.
