Re: looking for testers for if_rge - RTL8125/8126/8127 ethernet driver

Hi,

Turns out the realtek-re-kmod wasn't working out for me after all,
machine started repeatedly crashing.

Committed the port net/realtek-rge-kmod hoping to attract more testers.
So far, works out great for me. GMKTek M5 Plus / AMD 5825U / Dual RTL8215
FreeBSD 15.0-RC4-p1 releng/15.0-n280991-c7ccd5b3f879 GENERIC amd64

Testing with 2 clients, both 100 parallel streams iperf3 bidirectional
for 10 minutes did showed negligible load.

rge0@pci0:1:0:0:        class=0x020000 rev=0x05 hdr=0x00 vendor=0x10ec
device=0x8125 subvendor=0x10ec subdevice=0x8125
    vendor     = 'Realtek Semiconductor Co., Ltd.'
    device     = 'RTL8125 2.5GbE Controller'
    class      = network
    subclass   = ethernet
rge1@pci0:2:0:0:        class=0x020000 rev=0x05 hdr=0x00 vendor=0x10ec
device=0x8125 subvendor=0x10ec subdevice=0x8125
    vendor     = 'Realtek Semiconductor Co., Ltd.'
    device     = 'RTL8125 2.5GbE Controller'
    class      = network
    subclass   = ethernet

Cheers, Bernard.
