NAME

       rio_sport_is_active - Tests if a switch port has an active connection.

SYNOPSIS

       int rio_sport_is_active(struct rio_mport * port, u16 destid, u8 hopcount, int sport);

ARGUMENTS

       port
	   Master port to send transaction

       destid
	   Associated destination ID for switch

       hopcount
	   Hopcount to reach switch

       sport
	   Switch port number

DESCRIPTION

       Reads the port error status CSR for a particular switch port to determine if the port has an active link. Returns
       RIO_PORT_N_ERR_STS_PORT_OK if the port is active or 0 if it is inactive.
