All PHY attributes should be directly set to the transceiver after netlink.
MAC attributes should be set by interface up. Currently the macparams
netlink cmd contains mixed attributes of phy and mac settings. This patch
moves all phy settings to the netlink receive function for setting macparams.
This is the only way which doesn't change the userspace API and keep the
deprecated netlink interface alive.

This patch moves the setting of hardware panid address filtering
inside of interface up instead doing it it directly inside of netlink
interface. The netlink call which can only be called when netif isn't
running sets only the necessary panid value in sdata. After an
interface up the address filter will be set with this value.

Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next

H5 Specification says:
If a SYNC message is received while in the Active State, it is
assumed that the peer device has reset. The local device should
therefore perform a full reset of the upper stack, and start Link
Establishment again at the Uninitialized State. Upon entering the
Active State, the first packet sent shall have its SEQ and ACK
numbers set to zero.

This patch resets the HCI H5 driver data/state to unitialized and
reports an HCI hardware error event to notify the upper stack that
HCI synchronization has been lost. H5 will be re-synchronized and
upper stack should generate an HCI Reset command.

Disconnect flow may be invoked either from upper layer request,
or from event reported by the firmware.

In case of firmware event, driver need to release resources for the station but
not send another disconnect WMI command.

In case of upper layer request, WMI_DISCONNECT_STA_CMDID command need to
be issued for the firmware to perform disconnect on the MAC layer. Eventually,
event is expected to confirm MAC disconnect, but it is better to not wait for
firmware event and release station resources immediately. FW may fail to
report disconnect for various reasons, so one could not rely on event always reported.

Introduce parameter to distinguish 2 cases above to prevent double WMI command
issuing.
