[pve-devel] [PATCH common] net: tap_plug() needs to apply rate limiting

[Wolfgang Bumiller]

Any action we take in tap_plug() when using OVS will undo
our rate limiting, which means any hotplug change must
restore the previous rate setting.
Since this means tap_plug() would always be followed by a
tap_rate_limit() call anyway we just include the rate
parameter here and let the caller decide whether the full
tap_plug() is required or the simple tap_rate_limit()
suffices.
