Hi Marek,
Sure, we will do the option 3 with lan75xx.c, lan78xx.c, lan7xc, and lan7x.h as you like.

Should I keep this thread and make [PATCH v3] Add support for Microchip LAN78xx to submit?
Even though the new patch will also include LAN75xx as well?
Or new thread and include the LAN75xx in the title?
Please let me know.

Thank you again!
