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.

The internal representation of the LE white list needs to be cleared
when receiving a successful HCI_Reset command. A reset of the controller
is expected to start with an empty LE white list.

When the LE white list is not cleared on controller reset, the passive
background scanning might skip programming the remote devices. Only
changes to the LE white list are programmed when passive background
is started.

This patch change the actual crc handling while receive. Currently the

This patch changes the behaviour of IEEE802154_HW_RX_OMIT_CKSUM to add a

we remove the crc for frame parsing. This affect the driver layer

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.
