* [PATCH] PPC44x EMAC driver: disable TX status deferral in half-duplex modeEugene Surovegin2006-01-092-2/+3
| | | | | | | | | | | | | | Disable TX status deferral (EMACx_MR[MWSW=001]) in half-duplex mode. I have two reports when EMAC stops transmitting when connected to a hub. TX ring debug printouts show complete mess when this happens, probably hardware collision handling doesn't work quite well in this mode. This is relevant only for SoCs with EMAC4 core (440GX, 440SP, 440SPe). Tested on 440GX. Signed-off-by: Eugene Surovegin <ebs@ebshome.net> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
* [PATCH] ibm_emac: fix graceful stop timeout handlingEugene Surovegin2005-12-012-9/+31
| | | | | | | | | | | | | | | | | This patch fixes graceful stop timeout handling in PPC4xx EMAC driver. Currently, when we stop TX/RX channels we just do some number of loops without relying on actual spent time. This has finally bitten me on one of our systems (heavy network traffic during start up, RX channel is stopped several times to configure multicast list). Graceful channel stop can take up to 1 frame time, so I've added device specific timeout counter which depends on current link speed and calls to udelay() to really wait required amount of time before giving up.

* [PATCH] PPC 44x EMAC driver: add 440SPe supportEugene Surovegin2005-10-293-8/+29
| | | | | | | | | | | For some reason, the hardware designers made the polarity of one bit in the 440SPe's PHY interface register the opposite of all other PPC 440 chips. To handle this, abstract our access to this bit and do the right thing based on the configured CPU type.

* [PATCH] New PowerPC 4xx on-chip ethernet controller driverEugene Surovegin2005-10-2816-2801/+4028
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces current PowerPC 4xx EMAC driver with new, re-written from the scratch version. This patch is quite big (~234K) because there is virtualy 0% of common code between old and new version. New driver uses NAPI, it solves stability problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now. This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts are already upstream. Patch was acked by the current EMAC driver maintainer (Matt Porter). I will be maintaining this new version.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
