bitwise_rscan() is found to be hot spot in ovn-controller during OVN
scalability tests. It is triggered by lflow_run() when processing
lflow updates from SB ovsdb. The perf result shows:
+ 35.90% ovn-controller ovn-controller [.] bitwise_rscan
+ 13.39% ovn-controller [kernel.kallsyms]

Currently we treat set_multiq() calls specially in netdev and dpif-netdev:
every pmd thread must be stopped and set_multiq() is allowed to destroy and
recreate the device.
I think we can improve this by:
* Generalizing the mechanism to allow changing other parameters at runtime
(such as MTU).

Apart from some minor changes highlighted inline, looks good to me.

The previous definitions of these variables using designated

compile with MSVC, particularly if including these headers from C++

definitions the same on all platforms.

Recirculation feature probe messages sent from userspace are
suppressed by the OVS extension.
This patch changes the current behaviour to allow feature probe
for recirculation.

Hi Han Zhou,
Just curious and not related to the bitwise_rscan().
Do you get a chance to know what this kernel symbol is?

you can try "cat /proc/kallsyms" and see where it locates.

That's close. The principle is for megaflows to match

Hi Ryan,
I plan to test this patch in our scalability test environment, but it conflicts
with bce7cf on master, lfow_run()’s definition had been changed a lot.
Would it be possible to get a rebase of this patch on current master?
