From c1aaa34a95438f8897417febc3105209f6049f07 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Tue, 10 Jun 2014 09:40:24 +0900 Subject: [PATCH] net: sh_eth: Fix timing of RACT setting in sh_eth_rx() This patch fixes an issue that we cannot use nfs rootfs correctly on r8a7790 when the command below runs on a host PC. $ sudo ping -f -l 8 $BOARD_IP_ADDR Since the driver sets the RACT to 1 in the first while loop of sh_eth_rx(), the controller accepts a next frame into the next RX descriptor during the while loop. But, in the first while loop doesn't allocate a next skb. So, this patch removes the RACT setting in the first while loop of sh_eth_rx(). Signed-off-by: Yoshihiro Shimoda Signed-off-by: David S.
