-.Nd "Ethernet driver for SMC91Cxx based cards"
-.Sh SYNOPSIS
-To compile this driver into the kernel,
-place the following lines in your
-kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "device sn"
-.Ed
-.Pp
-Alternatively, to load the driver as a
-module at boot time, place the following line in
-.Xr loader.conf 5 :
-.Bd -literal -offset indent
-if_sn_load="YES"
-.Ed
-.Sh DEPRECATION NOTICE
