Subject: dpif: Log flow masks for "put" and "dump_next".
X-Git-Tag: sliver-openvswitch-1.10.90-3~6^2~76
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;ds=sidebyside;h=61fb711d271dd34b9dab967c7ba5700483cf568a;p=sliver-openvswitch.git

dpif: Log flow masks for "put" and "dump_next".

When debugging the system, it's useful to not just see the key but
also the mask.
