vhost tx retries can provide some mitigation against dropped packets due to a temporarily slow guest/limited queue size for an interface, but on the other hand when a system is fully loaded those extra cycles retrying could mean packets are dropped elsewhere. Up to now max vhost retries have been hardcoded, which meant no tuning and no way to disable for debugging to see if extra cycles spent retrying resulted in rx drops on some other interface. Add an option to change the max retries, with a value of 0 effectively disabling vhost tx retries. Signed-off-by: Kevin Traynor <ktray...@redhat.com>
No additional comments to Flavio’s for this patch. So will wait for your v3 and ack it.
