From 41664c03f6c96a1f8a91714309b36f1b5ca85610 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 12 May 2005 17:55:08 +1000 Subject: [PATCH] iseries_veth: Don't leak skbs in RX path Hi Andrew, Jeff, Under some strange circumstances the iseries_veth driver can leak skbs. Fix is simply to call dev_kfree_skb() in the right place. Fix up the comment as well.
