From: Karsten Keil <kkeil@...ux-pingi.de>
To: David Miller <davem@...emloft.net>
Cc: netdev@...r.kernel.org
Subject: [PATCH 3/8] Sometimes the ISDN chip only controls the D-channel
The B-channels are only accessed via the PCM backplane.
Add infrastruckture for this special mode.
Signed-off-by: Karsten Keil <kkeil@...ux-pingi.de>
