Thank you!  After several years of seeing dubiously licensed Microchip 
ROMs (which were very obviously built from gPXE/iPXE code without 
attribution or GPL compliance), it's a pleasure to see some source 
contributions coming from Microchip.

The driver appears to be largely identical to the existing smsc75xx 
driver.  I haven't checked the full set of differences, but at least the 
TX and RX datapath seem to use identical data structures and register 

Are the devices similar enough that it would make sense to extend the 
smsc75xx driver to cover both?
