In the iavf_init_arq function, if an exception occurs in the
iavf_config_arq_regs function, and the previously applied arq bufs
resource is released. This patch maintains the same modification
as the iavf_init_asq function to roll back resources.
Fixes: 87aca6d8d8a4 ("net/iavf/base: fix command buffer memory leak")

Can't image that you ARE superman to cover ixgbe,ixgbevf, i40e, now iavf.
It MUST BE done by some code scan tool, I don't believe you have real time to
read the whole code. Right ?
Sometimes, Defensive programming is good, but ... I prefer to the PMD
can run well every time, if failed, it must have some bugs.

Thanks your reply.
You are right. The resource leak is indeed scanned by tools, and then manually confirmed whether it is a problem.
Our team has been developing and maintaining for many years. Because the company process is not perfect,
the bug has not been promoted to the community, resulting in a lot of accumulation. I am currently Complete these things step by step.
In the near future, I hope you will give more guidance and maintain the dpdk intel driver together.

Can you tell me how to set up email reply? I don’t quite understand what you said about inline replies, and the green text and ">" are automatically generated?
