Spot on. I had 7500 in /kernel/drv/rge.conf. Now, with 7000, I get:
> # dladm show-linkprop -p mtu rge0
LINK PROPERTY PERM VALUE DEFAULT POSSIBLE
rge0 mtu r- 7000 1500 7000
# ifconfig rge0
rge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 7000 index 2
inet 10.1.8.2 netmask ff000000 broadcast 10.255.255.255
ether 0:14:c1:4c:3a:f9
Now to test...
