Subject: [PATCH ethtool 5/7] settings: simplify link_mode_info[] initializers
Date: Sun,  9 Aug 2020 23:24:32 +0200 (CEST)	[thread overview]
Message-ID: <92e78acec9d1b68ea048b39bbb079548df186c9f.1597007533.git.mkubecek@suse.cz> (raw)
In-Reply-To: <cover.1597007532.git.mkubecek@suse.cz>

Use macro helpers to make link_mode_info[] initializers easier to read and
less prone to mistakes. As a bonus, this gets rid of "missing field
initializer" warnings in netlink/settings.c

This commit should have no effect on resulting code (checked with gcc-11
and -O2).
