Well this does not work is identity address might not be the same as
RPA, using hci_copy_identity_address might leak the identity address
to other peer participating in the network.

Did you keep track what patches have been merged upstream? Id like to
first make the solution stable since even pings something makes the
kernel crash, so how about those:

  bluetooth: introduce l2cap_hdev_chan_connect
  bluetooth: add hci dev notifier
  bluetooth: introduce l2cap chan priv data
  bluetooth: export functions and variables
