[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. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
