dahdi/wcb4xxp driver used with Digium Wildcard B410 quad-BRI PCI card
unable to communicate with another ISDN device (ISDN phone, another port
of B410). It appears that B-channels are capable to transport data, but
D-channel is not.
Debug output added into the driver shows that packets are transmitted to
the D-channel, but no packets are received. Further investigation shows
that no interrupts received from Rx FIFO associated with D-channel,
although packets are delivered to the FIFO. I've found that problem is
in improper usage of chan->chanpos while indexing the fifo index
(bspan->fifos): chanpos starts from 1 and fifos starts from 0.
Therefore, garbage read instead of fifo number.

This needs some more testing before it's on by default. If the card is
otherwise functioning, these messages may be confusing to the user. If
the card is not functioning, the driver can be reloaded with debug to
check for this condition.
