REVISION SUMMARY
  The RTL8211F-VD is a replacement/upgrade for the RTL8211F.  Based on https://github.com/torvalds/linux/commit/bb726b753f75a4eeda291438f89dfd9b94783569, the only difference is the lack of the PCR2 register, which FreeBSD doesn't use.
  
  At least on my Radxa ROCK 4C Plus, the fallback ukphy(4) is unable to manage autonegotiation, whereas the attached patch allows rgephy(4) to attach and autonegotiation then works.

TEST PLAN
  Tested on my Radxa ROCK 4C Plus
