e1input: rework generic (virtual and real) E1 line operations
struct e1inp_line_ops {
int (*sign_link_up)(struct msgb *msg, struct e1inp_line *line);
int (*sign_link)(struct msgb *msg, struct e1inp_sign_link *link);
int (*error)(struct msgb *msg, int error);
};
The description of the operations is the following:
* sign_link_up is invoked if the signalling link becomes up. In A-bis
over IP, we have to wait until the other peer identifies itself as
a BTS/BSC device, then this function is invoked. This function is not
used by ISDN drivers, the signalling link can be set up just after
the line is created.
* sign_link is called if we receive OML/RSL message. This function
is used both by ISDN and A-bis over IP drivers.
* error is called if we receive a malformed message. It is used both
by ISDN and A-bis over IP drivers.
