will get into some troubles. As a side note, this patch is an updated version of a patch sent some years ago: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-

You might want to add a constant for TX_CSUM_NO_LIMIT or something like that, rather than a plain 0 which might be a little misleading.
