[PR] drivers/wireless/lpwan/rn2xx3: Patch read operation [nuttx]
linguini1 opened a new pull request, #17291:
URL: https://github.com/apache/nuttx/pull/17291
## Summary
This patch fixes an issue with the read operation where sometimes the `file_read` call would return a single ASCII hex byte instead of 2 and the parsing logic could not handle that scenario. Now packet data is read in large chunks to an internal buffer and incrementally parsed, making it robust to this problem (and likely much faster).
Closes #17273.
## Impact
The driver implementation should no longer have this read bug, and read operations should be faster. This is a change to the internal implementation, doesn't touch documentation or build system.
## Testing
Only verified that the code compiles without warnings/errors using the `raspberrypi-pico:usbnsh` configuration with the driver enabled.
Waiting for fix confirmation from @bskdany after device testing, marked as draft until then.

I am closing this because I was not able to test it and the InSpace team concluded that it did not solve their issue. I will possibly revisit this in the future.
