Ok, make sense. I'll send you updated patch set from 3-7 in a moment.

Since we in general try to avoid initializations upon declaration I'd
keep the status = HAL_STATUS_FAILED here. Even if it would be ok to move

Refactored bnep connect and disconnect calls to simplify and
keeping bnep related functionality behind curtains.
Provided bnep struct globally. bnep_connect calls takes
care of bnep_setup until interface up then connect callback
will be called. Provided bnep_set_watchdog. When interface is
up then only set watchdog. bnep_disconnect should be called
only when iface is up/connected.
