.Ox 4.2 .
.Sh AUTHORS
.An -nosplit
The
.Nm
driver was written by
.An Reyk Floeter Aq Mt reyk@openbsd.org .
.Sh CAVEATS
While the firmware supports reading module information for
.Xr ifconfig 8
.Cm transceiver
to use, it does not support writing to the module.
This prevents configuration of the module, which may prevent
.Xr ifconfig 8
from reading the right data from the module where other network
cards succeed.
