Hi Ido,
Yes it is related.
This specific error is related to the requested DEV_RX_OFFLOAD_CRC_STRIP, and
following patch should fix it because it adds to CRC strip capability to virtual
drivers:
https://patches.dpdk.org/patch/41359/
But perhaps we should also add some checks in examples as done in RSS check:
https://patches.dpdk.org/patch/41584/
There are a few pieces are moving, making it hard to manage, all these errors
should be detected and fixed by end of this week. Changes:
- We are removing old offload API and structus
- We are making ethdev more strict about what application request about offloads
and rss_hf
- We are in the process of deprecating CRC_STRIP flag
