Description

Hi, i'm trying to change the mtu settings to activate jumbo frames

No problem on guest, i can set to whatever value.

But on host, either with ifconfig or networksetup, i can't:

bash-3.2$ sudo ifconfig vboxnet6  mtu 9000
ifconfig: ioctl (set mtu): Operation not supported on socket
bash-3.2$ sudo networksetup -setMTU vboxnet6 9000
Could not find hardware port or device named vboxnet6.
** Error: The parameters were not valid.
bash-3.2$ 

versions

bash-3.2$ VBoxManage --version
4.3.6r91406
bash-3.2$ uname -ar
