Change MTU

Since almost all important devices in my network use an MTU (maximum transmission unit) of 9000, I looked high and low on how to change it on recalbox. The reason is that I wanted to try and optimize the Moonlight streaming as much as possible. By having less overhead, the cpu would maybe get a little more headroom (theoretically).

What I found is that at least currently, it IS possible to change it on a raspberry pi by issuing the command in SSH.
This changes it temporary for testing
`sudo ip link set dev eth0 mtu 9000`

or permanently
`sudo nano /etc/dhcpcd.conf

interface eth0
static ip_address=192.168.1.50/24
static routers=192.168.1.1
static domain_name_servers=192.168.1.1
mtu 1400
`

BUT, this only works when running an OS that supports this change (Raspberry Pi OS for example).

When it comes to Recalbox, apparently it is not supported to change MTU and it will always use the default,


I am not sure how much the MTU would change things, if at all. But it would be nice to have been able to test it.
Currently that does not seem possible. Maybe in the future.
