Not correct. Linux is perfectly fine with setting 9000 byte MTU on
ethernet devices that support it, and in fact just about every
gigabit ethernet driver supports it.
That macro you see in if_ether.h is just the value of the base MTU
limit, so larger MTU settings are easily allowable on a per-device
basis.
