Subject: sctp: missing set src and dest port while lookup output route
X-Git-Tag: v2.6.35-rc1~473^2~287^2~15
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6429d3dc4bd6251b01c11b851e23a4d60f079e06;p=platform%2Fupstream%2Fkernel-adaptation-pc.git

sctp: missing set src and dest port while lookup output route

While lookup the output route, we do not set the src and dest
port. This will cause we got a wrong route if we had set the
outbund transport to IPsec with src or dst port.
