Looking at the doc, and the code, none of those drivers (net/ixgbe,
net/atlantic) seem to support this feature.
I'll let the maintainers reply on the feasibility.

The documentation from the main repository provides a list of per
driver features:
https://doc.dpdk.org/guides/nics/overview.html
For an already released DPDK, the link becomes
https://doc.dpdk.org/guides-<version>/nics/overview.html.
Like, for example: https://doc.dpdk.org/guides-22.11/nics/overview.html
