Hi Marcel,
    The patch for pausing RFCOMM tx traffic during the grace period
when the encryption is dropped (as a result of the role change) is
attached.

Thanks
Jaikumar

Subject: [PATCH] Bluetooth: When encryption is dropped, do not send RFCOMM tx packets.

During a role change, the remote side drops the encryption of the RFCOMM
connection. We allow a grace period for the encryption to be reestablished,
before dropping the connection. During this grace period, the RFCOMM_SEC_PENDING
flag is set. Check this flag before sending RFCOMM tx packets.
