Subject: [PATCH]: isdn: netjet - blacklist Digium TDM400P

[2nd try ... 1st attempt didn't make it to netdev mailing list]

A quick google search reveals that people with this card are blacklisting it
in the initramfs and in the module blacklist based on a statement that it
is unsupported. Since the older Digium is also unsupported I'm pretty
confident that this newer card is also not supported.

lspci -xxx -vv shows

04:07.0 Communication controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface
        Subsystem: Device b100:0003
P.

----8<----
The Asterisk Voice Card, DIGIUM TDM400P is unsupported by the netjet driver.
Blacklist it like the Digium X100P/X101P card.
