Hi

The patch bri_dchan of bristuff is a patch to Zaptel that is used for
special handling of the D channel for HFC-based devices with Zaptel
drivers.

It defines an extra type of Zaptel channel:

#if defined(CONFIG_ZAPATA_BRI_DCHANS)
#define ZT_FLAG_BRIDCHAN (1 << 19)
#endif

And then goes on to provide special handling for Zaptel channels with
that flag.

This worked fine up til zaptel 1.4.11 . In zaptel.h for zaptel 1.4.11
you'll also find:

#define ZT_FLAG_MTP2 (1 << 19)
/* Repeats last message in buffer and also discards repeating messages sent to us */

Thus after applying the bri_dchan patch, both MTP2 and HFC D channels
will probably behave , well, differently.

The fix: change the bri_dchan patch to use 20 instead of 19. e.g:

+#if defined(CONFIG_ZAPATA_BRI_DCHANS)
+#define ZT_FLAG_BRIDCHAN (1 << 20)
+#endif
