configuration file allows to enable/disable FW broadcast filtering.
If MVM_FW_BCAST_FILTER_PASS_ALL is not defined in iwl-dbg-cfg.ini or

Instead of checking if we are associated when suspending with wowlan

Take the WoWLAN handling code out of the main suspend function,
dividing it into three parts: get_config (which is used before the
firmware is switched), switch_to_d3 (which handles the rebooting of
the hardware with the D3 firmware) and config (which configures the D3
firmware for WoWLAN operation). This is necessary to prepare for the
net-detect implementation, which will use only the switch_to_d3 part
of this flow.

These days we allow simultaneous LE scanning and advertising. Checking
for whether advertising is enabled or not is therefore not a reliable
way to determine whether directed advertising was used to trigger the
connection creation. The appropriate place to check (instead of the hdev
context) is the connection role that's stored in the hci_conn. This
patch fixes such a check in le_conn_timeout() which could otherwise lead
to incorrect HCI commands being sent.

The le_conn_timeout() may call hci_le_conn_failed() which in turn may
call hci_conn_del(). Trying to use the _sync variant for cancelling the
conn timeout from hci_conn_del() could therefore result in a deadlock.
This patch converts hci_conn_del() to use the non-sync variant so the
deadlock is not possible.

The reason for the revert is that we cannot have more than one module
initialization function and the SMP one breaks the build with modular
kernels. As the proper fix for this is right now looking non-trivial
it's better to simply revert the problematic patches in order to keep
the upstream tree compilable.

The "goto chip_reset" is a bit misleading, because it does not actually
issue a chip reset. Instead it is bypassing processing of other
interrupts and assumes that the tasklet will issue a chip reset.
In the case of RXORN this does not happen, so bypassing processing of
other interrupts will simply allow them to fire again. Even if RXORN
was triggering a reset, it is not critical enough to need the bypass
here.
