Subject: openvswitch: Use net_ratelimit in OVS_NLERR
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1815a8831fb04c60d73627816cb0b596266e9bee;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

openvswitch: 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.
