Brandon,

Before putting this new job online, the build issue should have been
fixed on the dpdk side.
All new submitted series are now getting a fail flag that we must
inspect to check whether it is because of this known issue or
something else.

Please, disable this job.

There is also the OpenSuse job failing.
Can you investigate?


Xiao, Maxime,

Anyone free to have a look on the vdpa build issue on Fedora Rawhide?
