Subject: [PATCH 5/5] e1000e: lower ring minimum size to 64
Date: Mon, 14 Apr 2008 10:06:19 -0700 [thread overview]
Message-ID: <20080414170619.23286.25518.stgit@localhost.localdomain> (raw)
In-Reply-To: <20080414170557.23286.71580.stgit@localhost.localdomain>
The lower limit of 80 descriptors in the ring is only valid for
one older 8254x chipset. All e1000e devices can use as low as
64 descriptors.
