Subject: drivers/net: ks8842 Fix crash on received packet when in PIO mode.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b10cec8a4e8167075b9e1ff3f05419769e7f381a;p=mv-sheeva.git

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.
