Subject: [PATCH nft 02/10] proto: reduce size of proto_desc structure
Date: Wed,  9 Dec 2020 18:49:16 +0100	[thread overview]
Message-ID: <20201209174924.27720-3-fw@strlen.de> (raw)
In-Reply-To: <20201209174924.27720-1-fw@strlen.de>

This will need an additional field. We can compress state
here to avoid further size increase.
