Subject: [PATCH net-next v4 06/14] mlx5: convert to ndo_set_rx_mode_async
Date: Tue, 31 Mar 2026 18:19:06 -0700 [thread overview]
Message-ID: <20260401011914.1716692-7-sdf@fomichev.me> (raw)
In-Reply-To: <20260401011914.1716692-1-sdf@fomichev.me>
Convert mlx5 from ndo_set_rx_mode to ndo_set_rx_mode_async. The
driver's mlx5e_set_rx_mode now receives uc/mc snapshots and calls
mlx5e_fs_set_rx_mode_work directly instead of queueing work.
mlx5e_sync_netdev_addr and mlx5e_handle_netdev_addr now take
explicit uc/mc list parameters and iterate with
netdev_hw_addr_list_for_each instead of netdev_for_each_{uc,mc}_addr.
Fallback to netdev's uc/mc in a few places and grab addr lock.
