====================
aqc111: revert endianess fixes and cleanup mtu logic

This reverts no-op commits as it was discussed:

https://lore.kernel.org/netdev/1557839644.11261.4.camel@suse.com/

First and second original patches are already dropped from stable,
No need to stable-queue the third patch as it has no functional impact,
just a logic cleanup.
====================
