Subject: [PATCH 1/3] net: ethtool: export conversion function between u32 and link mode
Date: Fri, 15 Apr 2016 00:34:59 +0200 [thread overview]
Message-ID: <1460673301-10599-2-git-send-email-tremyfr@gmail.com> (raw)
In-Reply-To: <1460673301-10599-1-git-send-email-tremyfr@gmail.com>
The function convert_legacy_u32_to_link_mode and
convert_link_mode_to_legacy_u32 may be used outside
of ethtool.c. We rename them to ethtool_convert_...
and export them, so we could use them in others
drivers and modules.
