Subject: [PATCH 01/30] solos: Fix length header in FPGA transfers
Date: Tue, 17 Mar 2009 21:29:02 +0000 [thread overview]
Message-ID: <1237325342.27681.330.camel@macbook.infradead.org> (raw)
In-Reply-To: <1237310370.27681.314.camel@macbook.infradead.org>
The length field shouldn't ever include the size of the header itself.
This fixes the problem that some people were seeing with 1500-byte
packets.
