Bug ID: 1110
Summary: i40e: runtime Rx/Tx queue setup is unusable
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev

probable-fix
Results that have been collected by an ethdev testing tool, [1], which is
opensource, suggest that i40e PMD might have a bug in runtime queue setup.
According to log [2], if a Tx queue has not been set up, starting the device
will
fail. Apparently, the driver does not take the runtime setup feature into
account
when queues are started in a loop. The proposed fix shows the gist of the
problem.
The said bug also manifests itself with regard to Rx queues.
