The voicebus interface constantly uses the same buffers for moving data
to/from the card. A fixed pool has less overhead in this case than
constantly mapping/unmapping the kmem_cache_alloced buffers.
Saves about ~2.608 us for each run of vb_isr on a 2.40 GHz Xeon test
machine.

This module parameter will allow patgen/pattest to be used only on FXO
ports. *ALL* FXO ports will be placed in digital loopback mode when
set.
The current intent is for this to be removed as an optional module
parameter when there is a channel by channel representation in sysfs.
Otherwise, a new IOCTL would have to be defined and a tool written in
order to support this. DAHDI-696.

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.
