From 7aa0076c497d6f0d5d957b431d0d80e1e9780274 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Tue, 23 Jul 2013 00:17:25 +0100 Subject: [PATCH] sfc: Enable RX scatter for flows steered by RFS Received packets are only scattered if this is enabled in both the matching filter and the receiving queue. This was not being done for filters inserted for RFS, so any packet requiring more than a single descriptor was dropped. Signed-off-by: Ben Hutchings Signed-off-by: David S.
