From ee76c1f821e75550644e084dea85743bbc934f91 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Fri, 2 Aug 2013 21:48:18 +0200 Subject: [PATCH] pcnet: Flush queued packets on end of STOP state Analogously to other NICs, we have to inform the network layer when the can_receive handler will no longer report 0. Without this, we may get stuck waiting on queued incoming packets.
