from man scp:
Can be used to pass options to ssh in the format used
in ssh_config(5). This is useful for specifying options
for which there is no separate scp command-line flag.
and from man ssh_config:
Specifies that a TCP/IP port on the local machine be
forwarded over the secure channel to the specified host
and port from the remote machine. The first argument
must be a port number, and the second must be host:port.
IPv6 addresses can be specified with an alternative
syntax: host/port. Multiple forwardings may be specified,
and additional forwardings can be given on the command
line. Only the superuser can forward privileged ports
