Which kind of hardware do you use ? We are using a SuperMicro board and the network driver is e1000. The revision of the chipset is 82546GB-copper (maps to e1000_82546_rev_3). This particular chipset does not support packet splitting, so we are looking for a hack on the skb layer. -- Dan Aloni da-x@monatomic.org, da-x@colinux.org, da-x@gmx.net - 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/ | ||||||||||||
