struct svc_xprt * svc_find_xprt(struct svc_serv * serv, const char * xcl_name, struct net * net, const sa_family_t af, const unsigned short port);
serv
pointer to svc_serv to search
xcl_name
C string containing transport's class name
net
owner net pointer
af
Address family of transport's local address
port
transport's IP port number
Return the transport instance pointer for the endpoint accepting connections/peer traffic from the specified transport class, address family and port.
Specifying 0 for the address family or port is effectively a wild-card, and will result in matching the first transport in the service's list that has a matching class name.
