This equation is the standard way to find the full length on any skb. For linear skbs, data_len is always zero. I asked Alan to use this formula so that greps on the source tree would always show data_len being taken into account, and thus usage would be consistent. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
