I believe you are correct. BTW, funny thing is I found several web pages by googling: http://manuals.fujitsu-siemens.com/serverbooks/content/manuals/html/broadcom/features.htm http://supportapj.dell.com/support/edocs/network/P29352/English/features.htm Fujitsu-Simens says: 'Jumbo frames (up to 9 KB) (except for BCM5721 and BCM5751)' Dell says: 'Jumbo frames (up to 9 kB) (only for BCM5721 and BCM5751)' :-) Jung-uk Kim _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
