From b10cec8a4e8167075b9e1ff3f05419769e7f381a Mon Sep 17 00:00:00 2001 From: Dennis Aberilla Date: Sun, 29 May 2011 11:46:54 +0000 Subject: [PATCH] drivers/net: ks8842 Fix crash on received packet when in PIO mode. This patch fixes a driver crash during packet reception due to not enough bytes allocated in the skb. Since the loop reads out 4 bytes at a time, we need to allow for up to 3 bytes of slack space.
