| A couple of points here:

| a little work as there is no ccid2 equivalent and so the whole thing
| isn't needed!
Many thanks for this information.
I currently hesitate to remove it from the CCID interface, it may be that we can
make use of it later (I am for instance thinking of the yet unresolved issue of
communicating MSS values between CCID module and main DCCP module).
But I have taken your comments on board, please find below the revised patch
which
removes the tx_insert_options within ccid3.c,
uploaded as 16d_deprecate_tx_insert_options.diff
-------------------> Revised Patch v2
<-------------------------------------------
[CCID 3]: Deprecate ccid3_hc_tx_insert_options
The function ccid3_hc_tx_insert_options only does a redundant no-op,
as the operation
DCCP_SKB_CB(skb)->dccpd_ccval = hctx->ccid3hctx_last_win_count;
is already performed _unconditionally_ in ccid3_hc_tx_send_packet.
Since there is further no current need for this function, it is removed
entirely. Many thanks for Ian McDonald for collaboration on this issue.
