Subject: [PATCH nft v2 4/8] debug: dump the l2 protocol stack
Date: Mon, 1 Aug 2022 15:56:29 +0200 [thread overview]
Message-ID: <20220801135633.5317-5-fw@strlen.de> (raw)
In-Reply-To: <20220801135633.5317-1-fw@strlen.de>
Previously we used to print the cumulative size of the headers,
update this to print the tracked l2 stack.
