|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device miibus"

|
|
Ethernet controllers which support a TCP Offload Engine (TOE), Remote DMA (RDMA),
|
|

|
|
.Cm full-duplex
|
|
mode is supported.
