From 65d6c2b42ecc0ca77bb3c0fe27fcbdc84fc7a79a Mon Sep 17 00:00:00 2001 From: Gerrit Renker Date: Sun, 10 Dec 2006 00:05:38 -0200 Subject: [PATCH] [DCCP] ccid: Deprecate ccid_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. Since furthermore, there is actually no present need for the entire interface function ccid_hc_tx_insert_options, it was decided to remove it also, to clean up the interface.
