My question was more in the other direction: should this test apply to
all the "port spaces" handled here? From looking at the code, it
appears the answer is yes -- it seems that putting a port in
local_reserved_ports reserves that port for IPv4 and IPv6, UDP, TCP,
SCTP, DCCP, everything, so we should probably reserve all RDMA CM ports too.
