Went looking for this sort of info, could not find it, so I thought I would
post what I did in the end.
OpenSolaris b124 comes with Marvell driver called "yge" instead of one you can
download for Solaris 10 called "yukonx" which I used on OpenSolaris until b124.
After upgrading to b124+ (from the console, as the network might be broken)
-bash-3.2# mv /etc/hostname.yukonx0 /etc/hostname.yge0
-bash-3.2# init 6
Your system should be on the network now
-bash-3.2# cp -p /etc/path_to_inst /etc/path_to_inst.before_remove_yukonx
-bash-3.2# pkgrm YUKONXsolx
The following package is currently installed:
YUKONXsolx Marvell Yukon Ethernet Controller 64 bit driver
(i386) 8.19.2.3

Removal of <YUKONXsolx> was successful.
-bash-3.2# diff path_to_inst path_to_inst.before_remove_yukonx

> "/pci at 0,0/pci8086,27e0 at 1c,4/pci1043,8142 at 0" 0 "yukonx"
-bash-3.2# init 6 # just to make sure everything is still working
Some thing like this should switch on Jumbo Frames/Packets
ifconfig yge0 unplumb # it would be nice if this was not need, ie do it on
next reboot instead
dladm set-linkprop -p mtu=4096 yge0 # it does support mtu 9000
dladm show-linkprop -p mtu yge0
ifconfig yge0 plumb `cat /etc/hostname.yge0` netmask + up
PS make sure no programes are using the raw device like snoop or dhcp server
Cheers
