From 01d73edb6561f0dfcded4d4a1bd551baf7fcb568 Mon Sep 17 00:00:00 2001 From: Sepherosa Ziehau Date: Thu, 18 Jul 2013 21:24:16 +0800 Subject: [PATCH] mbuf: revert part of b4e5a1079d852748f03f32aae87ecdda27a538d2 Restore wlan_seqno, since ether_vlantag has been used by WME. Fill the implicit padding on x86_64 and add comment for their possible use.
