       AF_ROSE - Rose amateur packet radio protocol family


       Rose  is  a protocol used extensively by radio amateurs. The Linux Rose
       protocol family permits access to  these  protocols  via  the  standard
       networking socket metaphor.

       The Rose protocol layer only supports connected mode.

       The only mode of operation is connected mode which is the mode used for
       a socket of type SOCK_SEQPACKET (stream sockets are  not  available  in
       Rose).   This  requires  that  the user ensures output data is suitably
       packetised, and that input data is read a  packet  at  a  time  into  a
       buffer of suitable size.

       Rose  addresses  consist  of  10  digits.  These  are  encoded  into  a
       sockaddr_rose structure which is provided to the relevant system calls.

       Rose has some unusual properties. Notably in  a  multi-user  system  an
       AX.25  address  is often associated with a user, and some users may not
       have such an association. a set of ioctl calls are provided  to  manage
       an association table.

       Rose supports the following socket options for SOL_ROSE. ROSE_T1 is the
       T11/T21 timer in 1/10ths of a second, ROSE_T2 is the T12/T22  timer  in
       1/10ths  of  a  second.  ROSE_T3,  is the T13/T23 timer in 1/10ths of a
       second.  It is possible for an application to  request  that  the  Rose
       layer  return  the Rose header as well as the application data, this is
       done via the ROSE_HDRINCL socket option.
