For such drivers, which do not support "possible" values for the MTU 
property, the <drv>_m_getprop() would return 'ENOTSUP' and we would 
display the current value of the MTU (as cached by MAC layer) in the output.

bash-3.2$ dladm show-linkprop -p mtu mxfe0
LINK         PROPERTY        VALUE          DEFAULT        POSSIBLE
mxfe0      mtu             1500           1500           1500

The meaning of 'possible' value, from dladm(1m) man page, is 'list of 
values the property can have' and in this case it will be 1500.
