Subject: flow_dissector: do not break if ports are not needed in flowlabel
X-Git-Tag: v4.9.8~4072^2~236
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=12c227ec89a70c14e3efcf102c5babece381e172;p=platform%2Fkernel%2Flinux-rpi3.git

flow_dissector: do not break if ports are not needed in flowlabel

This restored previous behaviour. If caller does not want ports to be
filled, we should not break.

Fixes: 06635a35d13d ("flow_dissect: use programable dissector in skb_flow_dissect and friends")
