Summary

There is no change in the source of the stats (t4_get_port_stats or
t4_get_vi_stats) but the per-port callout is gone.

This seems a bit odd as it means you will drop/pickup this lock several times. Maybe make the acquire of this lock in vi_refresh_stats() conditional on IS_VF instead and move the assertion here?

np marked an inline comment as done.Apr 1 2021, 5:57 PM

Acquire reg_lock around read_vf_stat instead of in a loop in the function.
