Subject: [PATCH v2 07/22] e1000: Remove unneeded i210 specific register code
Date: Wed,  1 Jun 2016 21:58:36 -0700	[thread overview]
Message-ID: <1464843531-1824-8-git-send-email-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <1464843531-1824-1-git-send-email-andrew.smirnov@gmail.com>

Despite having EEC(EECD) and EERD at "non-standard" offsets i210
aliases those registers to be accesible via regular addresses so none
of the code removed by this commit is really necessary.
