For 4k and 8k page size the TX control block needs an external scatter gather list.

What I was trying to say is that the macro in question determines the size of a scatter/gathter list that is external to the TX descriptor. The size is based on MAX_SKB_FRAGS and PAGE_SIZE. When PAGE_SIZE is larger than 8k I don't need the external scatter/gather list because all frags will fit in the native TX descriptor. -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
