Hi Lutz,

Actually the setting of this is not a real problem, as it works as expected (unplumb, set, plumb). 
However the property "mtu" permission is "r-" all the time, also if the setting 
can be changed.

If MTU can be modified, as shown below, the value should be "rw"

r...@nexenta3:/volumes# dladm set-linkprop -p mtu=4000 e1000g0
r...@nexenta3:/volumes# dladm show-linkprop e1000g0
LINK PROPERTY PERM VALUE DEFAULT POSSIBLE

e1000g0 mtu [b]r-[/b] 4000 1500 1500-9216

The current mtu showed above is 4000. This may be a bug of Brussel.
Anyway, it has been fixed and the issue does not exist on my system
with snv_136 installed.

Thanks,
Lucy
