Subject: [PATCH 069/293] sockaddr: add X.25 socket address decoding support
|
|
|
|
* sockaddr.c: Include <linux/x25.h>.
|
|
(print_sockaddr_data_x25): New function.
|
|
(sa_printers) <[AF_X25]>: New socket address handler.
|
|
* tests/net-sockaddr.c (check_x25): New function.
|
|
(main): Use it to check X.25 socket address decoding.
