From 4f8166809cf7cc93b04f850cde44da4dcf454121 Mon Sep 17 00:00:00 2001 From: t_jeang Date: Tue, 6 Jan 2009 12:06:02 +0000 Subject: [PATCH] [NETBACK] Try to pull a minimum of 72 bytes into the skb data area when receiving a packet into netback. The previous number, 64, tended to place a fragment boundary in the middle of the TCP header options and led to unnecessary fragmentation in Windows <-> Windows networking.
