RGE(4)                       Device Drivers Manual                      RGE(4)

NAME
     rge - Realtek 8125/8125B/8126/8127 PCI Express 10/100/1Gb/2.5Gb/5Gb/10Gb
     Ethernet device

SYNOPSIS
     rge* at pci?

DESCRIPTION
     The rge driver provides support for NICs based on the Realtek RTL8125,
     RTL8126, and RTL8127 PCI Express Ethernet controllers, including the
     following:

           ⊕   IOCrest IO-PCE8126-GLAN Adapter (5000baseT)
           ⊕   WisdPi WP-NA5000 Adapter (5000baseT)
           ⊕   Realtek 8125/8125B 2.5GbE Adapter (2500baseT)
           ⊕   Realtek 8126 5GbE Controller (5000baseT)
           ⊕   Rivet Networks Killer E3000 Adapter (2500baseT)
           ⊕   TP-LINK TL-NG421 Adapter (2500baseT)

     NICs based on the 8125 and 8125B are capable of 10, 100, 1000 and
     2500Mbps operation.  NICs based on the 8126 are also capable of 5000Mbps
     operation, while NICs based on the 8127 are additionally capable of
     10000Mbps operation.  All NICs support off-loading of checksum
     calculations for IPv4, TCPv4, and UDPv4, but not for xxxv6.

CAVEATS
     The rge driver support for the RTL8127 chip should be considered
     experimental.
