NAME
     net_getmtu - determine the MTU of a given network interface

SYNOPSIS
     #include 

     int net_getmtu(const net_data_t net, const phy_if_t ifp);


INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI).

PARAMETERS
     net    value   returned   from   a   successful   call    to
            net_protocol_lookup(9F).


     ifp    value   returned   from   a   successful   call    to
            net_phylookup(9F) or net_phygetnext(9F).


DESCRIPTION
     The net_getmtu() function  receives  information  about  the
     current  MTU of a network interface. The value returned from
     this function call should not be cached as the MTU of a net-
     work interface since it is not guaranteed to be constant.

RETURN VALUES
     The net_getmtu() function returns -1 if the network protocol
     does  not  support  this  feature  and otherwise returns the
     current MTU of the network interface.

CONTEXT
     The net_getmtu() function may be called from user,   kernel,
     or interrupt context.
