[DCCP]: Remove redundant statements in init_sequence (ISS)
This patch removes the following redundancies: 1) The test skb->protocol == htons(ETH_P_IPV6) in dccp_v6_init_sequence is always true since * dccp_v6_conn_request() is the only calling function * dccp_v6_conn_request() redirects all skb's with ETH_P_IP to dccp_v4_conn_request() 2) The first argument, `struct sock *sk', of dccp_v{4,6}_init_sequence() is never used. (This is similar for tcp_v{4,6}_init_sequence, an analogous patch has been submitted to netdev and merged.) By the way - are the `sport' / `dport' arguments in the right order? I have made them consistent among calls but they seem to be in the reverse order. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
