From d301e3256866bfd3ae3093aeb43d3ca9570d758e Mon Sep 17 00:00:00 2001 From: James Chapman Date: Wed, 9 May 2012 23:43:09 +0000 Subject: l2tp: fix data packet sequence number handling If enabled, L2TP data packets have sequence numbers which a receiver can use to drop out of sequence frames or try to reorder them. The first frame has sequence number 0, but the L2TP code currently expects it to be 1. This results in the first data frame being handled as out of sequence. This one-line patch fixes the problem.
