[bluetooth-dev] Reg. Data transfer between L2CAP and RFCOMM

When L2CAP receives data to be sent to RFCOMM which of the 2 possibilities can occur: -
1)L2CAP sends a read indication to RFCOMM on receipt of which RFCOMM calls L2CAP_DataRead passing a pointer to its buffer which is filled up by L2CAP.
2)L2CAP calls RFCOMM_DataReceive and passes a pointer to  L2CAP's buffer from which RFCOMM will read the data.
