usb: gadget: u_ether: Fix MTU size mismatch with RX packet size
commit 0a88fa22 upstream. Fix the MTU size issue with RX packet size as the host sends the packet with extra bytes containing ethernet header. This causes failure when user sets the MTU size to the maximum i.e. 15412. In this case the ethernet packet received will be of length 15412 plus the ethernet header length. This patch fixes the issue where there is a check that RX packet length must not be more than max packet length.
