From a0bc3487e431eaea381c2c882a41274e9a02f028 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 16 Dec 2013 18:56:24 +0000 Subject: [PATCH] sfc: Fix RX drop filters for EF10 When we insert an filter, the firmware checks that the given RX queue index is in range even if it will not be used. In case we're inserting a drop filter, pass the value 0.
