We have experienced multiple crashes due to memory corruptions,
which happend after multiple kernel complains about "BUG: Bad page state".
Using debug commit dba1b8a7ab68 ("mm/page_pool: catch page_pool memory leaks")
we have caught the detailed reason:
page dumped because: page_pool leak
which should probably be fixed with ms commit:
c3198822c6cb ("net: esp: fix bad handling of pages from page_pool")
RHEL9.5 has already backported this commit along with several others,
so let's backport all of those commits in order to simplify later rebase.
