Content-Type: text/plain; charset=ISO-8859-1 List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , I am working on changes to xilinx_lltemac.c that support both the SDMA and FIFO TEMAC's. I was wondering if anyone else had done anything already ? I have it pretty much working with a few issues: every so often the read FIFO gets out of sync and I have to reset it dropping atleast one packet. Somehow something is screwed up that is breaking the Busybox Web server. This is really weird because nothing else seems to be broken. I have no clue how a driver that has no idea what is in the packets passing through it can selectively screw up HTTP packets, but I have proven to myself that the problem is in the driver - despite the my beleif that is impossible. Anyway is there any interest in an LL FIFO TEMAC driver ? Or adding the FIFO code to the SDMA TEMAC code ? It only adds a couple of dozen lines to the driver. -- Dave Lynch DLA Systems Software Development: Embedded Linux 717.627.3770 dhlii@dlasys.net http://www.dlasys.net fax: 1.253.369.9244 Cell: 1.717.587.7774 Over 25 years' experience in platforms, languages, and technologies too numerous to list.
