From 40dc9ab277eb3d2d3d3442c20accb5dfa577e680 Mon Sep 17 00:00:00 2001 From: Andrea Merello Date: Thu, 3 Oct 2013 21:18:37 +0200 Subject: [PATCH] atl1e: enable support for NETIF_F_RXALL and NETIF_F_RXCRC features This patch allows (optionally, via ethtool) the atl1e NIC to: - Receive bad frames (runt, bad-fcs, etc..) - Receive full frames without stripping the FCS. This has been tested on my board by injecting runt and bad-fcs frames with a FPGA-based device. The particular scenario of receiving very short frames (<4 bytes) without passing FCS to the upper layer has been also tested: This could be potentially dangerous because the driver performs a 4 byte subtraction on the frame length, but I finally have NOT added anything to avoid this because it seems the NIC always discards frames so much short.. If someone still have some reason to worry about this, please tell me.. I will add an explicit SW check.. Signed-off-by: Andrea Merello Signed-off-by: David S.
