rge(4) RTL8126 simple testing

I recently upgraded my home network using a few BrosTrend 5Gb
cards (RTL8126) with 14-STABLE (1eb2beb3686c) and the latest commit 
(3170b35) to the GitHub repo for if_rge.  It was either these cards or a 
couple of Intel X550-T2 cards, but less power and less heat were the 
deciding factors.

For the most part, they seem to work very well, except that they cannot 
negotiate a 2500Base-T connection.  They can negotiate 1000baseT and 
5000Base-T.  This was with two different cards connecting to two 
different devices.  If manually set, they will try for awhile than 
fall-back to 1000baseT.

One other oddity is that rge0 has "ClockPM disabled", but I have not 
looked into that.

The networking hardware:
- 3 BrosTrend 5Gb NIC's[1]  (5Gb)
- Zyxel NWA130BE[2]  (2.5Gb port)
- TRENDnet TEG-S591[3]  (connected the NIC to its 10Gb port)
- Nokia ONT XS-010X-Q[4]  (10Gb port)
