Subject: [PATCH iproute2-next v3 7/8] iplink: Move data structures to block of their users
Date: Thu, 22 Feb 2018 15:02:05 +0200	[thread overview]
Message-ID: <1519304526-18848-8-git-send-email-serhe.popovych@gmail.com> (raw)
In-Reply-To: <1519304526-18848-1-git-send-email-serhe.popovych@gmail.com>

This will consolidate data and code using it in single place and prepare
for upcoming ->parse_opt() method change.
