From 172e269edfce34bac7c61c15551816bda4b0f140 Mon Sep 17 00:00:00 2001 From: Edward Cree Date: Tue, 20 Apr 2021 13:29:35 +0100 Subject: sfc: ef10: fix TX queue lookup in TX event handling We're starting from a TXQ label, not a TXQ type, so efx_channel_get_tx_queue() is inappropriate. This worked by chance, because labels and types currently match on EF10, but we shouldn't rely on that.
