Only two mISDN hardware drivers emit MPH_INFORMATION_IND messages and both use a different payload:
- hfcsusb (HFC-based USB dongle) sends a set of ph_info + ph_info_ch structures
which contain the complete state information of the port
(including internal hw-specific state and flags).
- hfcmulti which sends a single integer, a single L1_SIGNAL_* event.
We now try to guess the type of message from the payload length.
The hfcmulti signals are converted to FreeTDM alarm flags; the hfcsusb
state/flags are defined in kernel internal hw-specific headers and are ignored ATM (todo).
