From 1cc5a735185a963ed9324a65e1f2db02bf52c0d4 Mon Sep 17 00:00:00 2001 From: Giuseppe CAVALLARO Date: Wed, 15 Feb 2012 00:10:37 +0000 Subject: stmmac: do not discard frame on dribbling bit assert If this bit is set and the CRC error is reset, then the packet is valid. Only report this as stat info. Signed-off-by: Giuseppe Cavallaro Signed-off-by: David S.
