[ipxe-devel] [PATCH 0/2] lan78xx: Adding Microchip lan78xx driver support

[Ravi.Hegde at microchip.com]

Hi Michael,

The device is available now. Do you (or anyone) need the device? I appreciate the feedback.

Thank you
Ravi

It has somewhat similar MAC. Phy is different(driver may not do anything differently). Has OTP.
I thought it would clutter the smsc75xx code if I try to combine. 

Thanks

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 values.

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

Thanks,

Michael
