Subject: datapath: Use net_ratelimit in OVS_NLERR
X-Git-Tag: sliver-openvswitch-2.1.90-1~8^2~10
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=13fe68421792da50e40025c587f790a608431f8f;p=sliver-openvswitch.git

datapath: Use net_ratelimit in OVS_NLERR

Each use of pr_<level>_once has a per-site flag.

Some of the OVS_NLERR messages look as if seeing them
multiple times could be useful, so use net_ratelimit()
instead of pr_info_once.
