If the subsequent allocation or creation of\nregular TX queues fails, the error handling paths omit the teardown of the\nXDP TX queues, leading to a resource leak.\n\nFix this by explicitly destroying the XDP TX queue subset at the two\nmissing failure points.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing\nv6.13-rc1. The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still\npresent in v7.1-rc7.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have\nan ENA device to test with, no runtime testing was able to be performed."
