I have defined getMaxPacketSize and setMaxPacketSize method to implement Jumbo frame support. get method is returning 9000 value, but when I tried to run ifconfig command:
"sudo ifconfig en16 mtu 4000"
it is giving message : (set mtu): invalid argument
and does not showing any message in system.log file.
Kindly help me.
Thanks in advance,
Sandeep
