syncookies: add support for ECN
Allows use of ECN when syncookies are in effect by encoding ecn_ok into the syn-ack tcp timestamp. While at it, remove a uneeded #ifdef CONFIG_SYN_COOKIES. With CONFIG_SYN_COOKIES=nm want_cookie is ifdef'd to 0 and gcc removes the "if (0)". Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>
