From 60031fcc17057e21566ed34ba23e93fffda1aa27 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Wed, 12 Jan 2011 18:39:40 +0000 Subject: [PATCH] sfc: Move TX queue core queue mapping into tx.c efx_hard_start_xmit() needs to implement a mapping which is the inverse of tx_queue::core_txq. Move the initialisation of tx_queue::core_txq next to efx_hard_start_xmit() to make the connection more obvious.
