From: Eli Britstein <[email protected]>
In the cited commit, XPS was introduced. It is NA for non-pmd ports.
Upon port creation it is indeed disabled, but at port reconfigure, the
condition of netdev_is_pmd() is missing.
As a result, XPS is configured, and such messages are repeating in the log:
DBG|Core 2: New TX queue ID 0 for port 'v1_r'.
Fix it.
Fixes: 324c8374852a ("dpif-netdev: XPS (Transmit Packet Steering)
implementation.")
