we just install a fresh almalinux 10.1 without any kind of external repo to
computer which has 2 different realtek card:
# lspci -nn|grep -i eth
03:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8125
2.5GbE Controller [10ec:8125] (rev 05)
04:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.
RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8161] (rev
15)

and it's working fine with the original r8169 driver with 2.6Gb/s.
so what was the reason for kmod-rr8125?
