That minimum is not needed in full duplex ethernet (it was there
to ensure 512bits on the wire for collision detection).

Modern ethernet drivers have no problem sending smaller
packets when the link is full duplex. Arp's on full duplex
wire are usually shorter.

xorps pseudo arp deamon is/was throwing those away.
