Subject: [PATCH] drivers/net: ks8842 Fix crash on received packet when in PIO mode.
Date: Wed, 18 May 2011 14:51:14 -0700 (PDT)	[thread overview]
Message-ID: <2062.44194.qm@web120510.mail.ne1.yahoo.com> (raw)


This patch fixes a kernel crash during packet reception due to not enough allocated bytes for the skb. This applies to the driver when running in PIO mode in an ISA bus setup.
