DESCRIPTION
     tsix_set_mac_byrhost sets the MAC label of all outgoing communication on
     fd , which must be associated with a socket, to the default MAC label for
     that host.  If lbl is not NULL, lbl will point to that MAC label upon
     successful execution of tsix_set_mac_byrhost.

     CAP_NETWORK_MGT , CAP_MAC_UPGRADE , CAP_MAC_DOWNGRADE ,
     CAP_MAC_RELABEL_OPEN , and CAP_MAC_MLD capabilities in the permitted
     vector of its capability set.

     If _SC_IP_SECOPTS is not in effect, tsix_set_mac_byrhost always returns
     success.

     tsix_set_mac_byrhost returns 0 if successful, -1 otherwise.
