I see, is following correct:
All thunderx, octeonx & octeontx2 only supports VF in the DPDK, and PF is
supported by Linux kernel driver. And Linux kernel driver doesn't support
arch32.
Is something changed in kernel driver side to drop the 32bit support?
If it was not supported at all, what is the motivation to disable the DPDK
drivers now?
