From: Jiri Slaby (SUSE) <jirislaby@xxxxxxxxxx> commit 3319dbb3e755398f254c3daa04b9030197137efe upstream. ef100_enqueue_skb() generates a valid warning with gcc-13: drivers/net/ethernet/sfc/ef100_tx.c:370:5: error: conflicting types for 'ef100_enqueue_skb' due to enum/integer mismatch; have 'int(struct efx_tx_queue *, struct sk_buff *)' drivers/net/ethernet/sfc/ef100_tx.h:25:13: note: previous declaration of 'ef100_enqueue_skb' with type 'netdev_tx_t(struct efx_tx_queue *, struct sk_buff *)' I.e. the type of the ef100_enqueue_skb()'s return value in the declaration is int, while the definition spells enum netdev_tx_t. Synchronize them to the latter.
