Herbert, UDP peek support is very buggy anyway, because of deferred checksums __skb_checksum_complete() will happily manipulate csum, ip_summed, csum_complete_sw & csum_valid Ideally, peek should never touch skb (but skb->users) -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
