{bp-15285} net: Add buffer pool to replace connection allocation

[jerpelea]

Summary

patches included:

net: Add buffer pool to replace connection allocation
net: Optimize ipfwd and wrbuffer by buffer pool

Our net socket connection allocations are powerful but redundant because they're implemented once in each protocol. This is not good for further optimizing and extending to other allocations, so maybe we can add a common implementation for the usage.

No, this PR does not fully meet the NuttX requirements. While it provides a summary of the changes, it lacks crucial details.

Here's a breakdown of what's missing:

• Insufficient Summary Detail: While the summary explains the why, it's missing the how. It mentions a buffer pool but doesn't explain how it works or how it replaces the connection allocation. What are the mechanics? What data structures are involved?
• Missing Issue References: There's no mention of related NuttX or NuttX Apps issues or pull requests. These are essential for tracking the context of the changes.
• Incomplete Impact Assessment: Simply stating "RELEASE" isn't sufficient. Each impact category (user, build, hardware, documentation, security, compatibility) needs a "YES" or "NO" answer, and if "YES," a description of the impact. For example, does this change require users to modify their code? Does it change any Kconfig options? Does it affect any specific architectures or boards? Does the documentation need to be updated? Are there any potential security implications of using a shared buffer pool?
• Inadequate Testing Information: "CI" isn't enough. The PR needs to specify the local testing environment (host OS, CPU, compiler) and the target(s) tested (architecture, board, configuration). Critically, it's missing the actual testing logs before and after the change. These logs are crucial for demonstrating that the changes work as intended and don't introduce regressions.

In short, the PR needs to be significantly expanded to provide the required information before it can be properly reviewed.
