Realtek interface #1 always goes to 100BastT, not gigabit

[erickengelke]

I have a commodity board with two realtek devices.  OpnSense names one em0 and the other re0.
em0 always connects at 1000BaseT, whereas I can never get re0 to work at 1000BaseT, it always goes to 100BaseT no matter which mode I select.  It has been this ever since 19.1 was installed, prior to that it was 1000BaseT.

Speedtest.net rating have dropped from 143Mbps to 97Mbps.  So this is reflected with in the data transfer rates.

Is there something about the Realtek driver which makes it not work with 1000BaseT?
