[PATCH] ipt_TOS fix.

Linus, please apply v2.4.0. ipt_TOS checksum calculations were completely broken, causing bad csum packets. Whoever implemented it didn't understand the code it was copied from. This fixes the problem (tested in userspace against all TOS changes). Rusty. -- Premature optmztion is rt of all
