.SH DESCRIPTION
.sp
.LP
The \fBnet_phylookup()\fR function attempts to resolve the interface name passed in with the network protocol.
.sp
.LP
When called successfully, the value returned represents a network interface that exists, at the time of the call, within the scope of the network interface. This value is only guaranteed to be unique for a name within the scope of the network protocol.
.SH RETURN VALUES
.sp
.LP
The \fBnet_phylookup()\fR function returns -1 if it is not supported by the network  protocol,  and 0 if the named network interface does not exist (or is otherwise  unknown).  Otherwise, it returns  a  value  greater  than 0 representing a network interface that currently exists within the scope of this network protocol.
.SH CONTEXT
.sp
.LP
The \fBnet_phylookup()\fR function may be called from user,  kernel, or interrupt context.
