I'm hopeful for 6.2, but it needs a respin I haven't seen yet.

Long,

For the reasons below, we should not have merged the MANA PMD in DPDK 22.11.
We must not assume dependencies until they are upstream.
This is a red flag on the PMD, a revert is possible.

Jason,

Please could you tell us what is the expected date of release
of the MANA support in Linux and rdma-core?
