While waiting for your help, i found and apply the patch to my rev.1.103 (the patch from old mailing lists which Brad Smith tested on BCM 5708 with rev.1.96). I leave my mii/brgphy.c original rev.1.104 (5.5 base) as it already includes the changes from patch. Now It is possible to set my BCM5709 hardmtu to jumbo size as needed. But something goes wrong with patch and dhclient on my bnx interfaces does not work (and i found that someone has posted that issue with high packet loss on a patched bnx already year ago with patch applied to rev.1.100 on BCM5709). DHCP REQ-ACK cant negotiate (seems that REQ transmition failed by bnx).
So i can only setup the interface as static IP, but even ARP (mac address) not resolved for directly connected hosts.
