correct. you are not allowed to mix segments from other packets in 
bluetooth. basically, once you start sending the segmented acl data 
packet you must send it all in order. tx_pkt chain is the current l2cap 
packet that will be sent as segmented acl packet (per ACL connection).

you are probably looking for ng_l2cap_lp_deliver(). if tx_pkt is not 
NULL then we are not allowed to start new transfer and must continue to 
send ACL packet segments (but only up to max. number of ACL packets 
device can hold in its buffers). if tx_pkt is NULL then we should get 
next l2cap command from the queue (per ACL connection), chop it into 
segments and send it down to hci layer
