2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------
From: Fernando Luis Vazquez Cao <ferna...@oss.ntt.co.jp>
commit 1ed2f73d90fb49bcf5704aee7e9084adb882bfc5 upstream.
The mask indicates the bits one wants to zero out, so it needs to be
inverted before applying to the original TOS field.
