Hello:

This series was applied to netdev/net.git (main)

When mana_create_rxq() fails partway through initialization (e.g. the
hardware rejects the WQ object creation), the error path calls
mana_destroy_rxq() to tear down a partially-initialized RXQ.
This exposed multiple issues in mana_destroy_rxq() path, as it assumed
the RXQ was always fully initialized, leading to multiple issues:

1. xdp_rxq_info_unreg() was called on an unregistered xdp_rxq,
   triggering a WARN_ON ("Driver BUG") in net/core/xdp.c.

[...]
Here is the summary with links:

You are awesome, thank you!
