Subject: [PATCH 4/8] e1000e: lower ring minimum size to 64
Date: Wed, 23 Apr 2008 11:09:19 -0700 [thread overview]
Message-ID: <20080423180919.24972.67080.stgit@localhost.localdomain> (raw)
In-Reply-To: <20080423180900.24972.84015.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.
