Did you try the official driver? net/realtek-re-kmod

Take a look at https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=275882 and https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=283887.

Best solution - add Intel NIC. I don't understand why manufacturers continue to use Realtek NICs.

Yes , it really doesn't work , its a pci express card
My intergrated network adapter is worse it even doesn't work on linux normally.

Please try the net/realtek-rge-kmod port or package (very fresh, don't see it in the FreeBSD-ports-kmod repo yet)
This driver is planned to land in base.

Thanks. Out of curiosity, how does it improve on net/realtek-re-kmod198 which seems to work reliably for me?

Did you have success getting the Realtek RTL8125 to work?
I'm asking as I have it working reliably on both of my FreeBSD 15.0-RELEASE systems - I have a couple of tweaks in /etc/rc.conf - see below. Oh, and I use the net/realtek-re-kmod198 driver as the official net/realtek-re-kmod had (has still?) serious problems.

Code:

# Realtek RTL8125 ethernet network adapter
ifconfig_re0="DHCP -rxcsum -txcsum"
ifconfig_re0_ipv6="inet6 accept_rtadv -rxcsum6 -txcsum6"
