mount.nfs: Do not send pmap inquire when port is specified
|
|
|
|
When the port is specified on the command line do not
|
|
send a pmap inquire asking for the port. Instead use
|
|
the given port in the NFS ping. If the ping fails,
|
|
assume a bad port was given and now go ask the server
|
|
for the correct port.
