This change affects data structures storing ERTM state and control
fields, and adds new definitions for states and events.  An
l2cap_seq_list structure is added for tracking ERTM sequence numbers
without repeated memory allocations.  Control fields are carried in
the bt_skb_cb struct rather than constantly doing shift and mask
operations.

Are these two still needed? I saw you moved others to l2cap_core.c
which is fine but what about these?

Since these macros are unrelated to ERTM, that would be a separate patch.

I think all the macros traditionally land in the header files because there are no #defines in the l2cap*.c files. However, I see that many other .c files in net/bluetooth do have #defines.

It's not that I "moved" the other macros, as much as my ported code had static functions instead. I tried to minimize changes to the ported code rather than minimize changes to the upstream code.
