Um? this would forbid to use any other port than 3260 for any of the
protocols stated above. That doesn't make sense neither for iSCSI nor
for the other ones.

The code should make sure that the port is in range <0,65536> and don't
force to use a certain port. Ohterwise we wouldn't need a port field.

NACK to this approach.
