From: Stephen Hemminger Date: Fri, 1 Dec 2006 22:29:33 +0000 (-0800) Subject: [PATCH] sky2: receive error handling fix X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5df791117afedf7fdc67dc0842dab4859e3edf69;p=linux-beck.git [PATCH] sky2: receive error handling fix If sky2 detects out of memory, or gets a bad frame, it reuses the same receive buffer, but forgets to poke the hardware. This could lead to the receiver getting stuck if there were lots of errors.
