Build Update for istokes/ovs
Duration: 1 hr, 4 mins, and 34 secs
Commit: 9425b8d (vhost_retry)
Author: Kevin Traynor
Message: netdev-dpdk: Enable tx-retries-max config.
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 tx 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
Add an option to change the max retries, with a value of
0 effectively disabling vhost tx retries.
