Subject: [PATCH 06/12] src: netlink: don't truncate set key lengths
Date: Sun, 16 Aug 2015 21:05:49 +0200	[thread overview]
Message-ID: <1439751955-31190-7-git-send-email-fw@strlen.de> (raw)
In-Reply-To: <1439751955-31190-1-git-send-email-fw@strlen.de>

If key is e.g. 12 bits, pretend its 16 instead of 8.  This is needed
to make sets work with header fields with size not divisible by 8.
