[ Upstream commit 4539f91f2a801c0c028c252bffae56030cfb2cae ]
On startup, ovs-vswitchd probes different datapath features including support for timeout policies. While probing, it tries to execute certain operations with OVS_PACKET_ATTR_PROBE or OVS_FLOW_ATTR_PROBE attributes set. These attributes tell the openvswitch module to not log any errors when they occur as it is expected that some of the probes will fail.
For some reason, setting the timeout policy ignores the PROBE attribute and logs a failure anyway. This is causing the following kernel log on each re-start of ovs-vswitchd:
kernel: Failed to associated timeout policy `ovs_test_tp'
Fix that by using the same logging macro that all other messages are using. The message will still be printed at info level when needed and will be rate limited, but with a net rate limiter instead of generic printk one.
The nf_ct_set_timeout() itself will still print some info messages, but at least this change makes logging in openvswitch module more consistent.
