Hi Peter,

Even though the legacy user space code uses typedefs for HCI and L2CAP
(which is why typedefs are probably ok for your 1st patch) the general
direction should be to try to get rid of them where they're not strictly
necessary. The kernel side headers don't use them either (take a look at
include/net/bluetooth/l2cap.h and hci.h).

Therefore, I think it'd be good if you'd from the start avoid them in
this a2mp code. Later it'd be good to have a cleanup patch to convert
the L2CAP and HCI definitions to not use them either.

Johan

I'll drop the typedefs and resend.

Peter.

ack (taking that typedef is a bluez standard way)
