That's something Maxime can see on RHEL8 with CX6 devices.
I remember seeing it too in the (recent) past, probably when working
with our QE.
So far, I did not associate this log presence to functional issues.


Looking at DPDK mailing lists:
http://inbox.dpdk.org/dev/?q=%220xFFFF+is+not+power+of+2%22
http://inbox.dpdk.org/users/?q=%220xFFFF+is+not+power+of+2%22

So we are not the only ones seeing this.

I don't mind.
Logs were coming from OVS unit tests but the same can most likely be
reproduced with testpmd.
