The dohwcksum is not an rge option, it is an ip option (hence it is named ip:dohwcksum) and it transcends NIC drivers.

I once had a switch that lost its mind and wouldn't let big packets through unscathed. We could telnet, ping, ftp, and do all sorts of things through the switch, but we couldn't push NFS through. These sorts of failures can be difficult to isolate. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
