We did some changes on the L2CAP configuration process and its behaviour
is bit different now. That justifies a updated on the L2CAP version.

This patch introduces two new ioctls: HCIUARTSETFLAGS and
HCIUARTGETFLAGS. The only flag available for now is HCI_UART_RAW_DEVICE
which allows to initialize a UART device into RAW mode from userspace.
This is particularly useful for experimenting with Bluetooth controllers
that don't yet have proper support in BlueZ.

Purely a cosmetic change, it doesn't change the code flow.

Probably a typo error. We were using the wrong struct to get size.

The extended L2CAP features requires that one should initiate a
ConfigReq after send the ConnectionRsp. This patch changes the behaviour
of the configuration process of our stack.

When we try to send a message bigger than the outgoing MTU value
EMSGSIZE (message too long) should be returned.

Now we also check if can push skb userspace just after receive a new
skb instead of only wait the l2cap_busy_work wake up from time to time
to check the local busy condition.

backlog queue is the canonical mechanism to avoid race conditions due
interrupts in bottom half context. After the socket lock is released the
net core take care of push all skb in its backlog queue.

Using a lock to deal with the ERTM race condition - interruption with
new data from the hci layer - is wrong. We should use the native skb
backlog queue.

If such event happens we shall reply with a Command Reject, because we are
not expecting any configure request.

When mode is mandatory we shall not send connect request and report this
to the userspace as well.

Since now we have checks for the supported mode before on
l2cap_info_rsp we can remove the check for it here.

If our mode is Basic Mode we have to refuse any ConfigRsp that proposes
a different mode.
