* skge: use per-port phy lockingStephen Hemminger2007-03-231-3/+3
| | | | | | | | | Rather than a workqueue and a per-board mutex to control PHY, use a tasklet and spinlock. Tasklet is lower overhead and works just as well for this. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* skge: fix transmitter flow controlStephen Hemminger2007-02-271-2/+1
| | | | | | | | | | | | It looks like the skge driver inherited another bug from the sk98lin code. If I send from 1000mbit port to a machine on 100mbit port, the switch should be doing hardware flow control, but no pause frames show up in the statistics. This is the analog of the recent sky2 fixes. The device needs to listen for multicast pause frames and then not discard them.

* [PATCH] skge: better flow control negotiationStephen Hemminger2006-10-111-5/+17
| | | | | | | | | Do flow control negotiation properly. Don't let auto negotiation status limit renegotiation. Separate desired pause values from the result of auto negotiation. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] skge: fix stuck irq when fiber downStephen Hemminger2006-10-111-1/+2
| | | | | | | | | The PHY interrupt from the internal fiber is getting stuck on when the link is down. Add code to handle the transition and mask it. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] skge: fiber supportStephen Hemminger2006-09-261-7/+30
| | | | | | | | | Add support for older fiber versions of the SysKonnect board. These chipsets use an internal PHY so they require special handling. The older sk98lin driver already supported these Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] skge: use NAPI for transmit completeStephen Hemminger2006-09-061-1/+0
| | | | | | | | | The skge driver has much better performance if transmit done is handled in NAPI softirq. Change from doing transmit locking in driver (LLTX) and use device lock. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] skge: fix truncated collision threshold maskStephen Hemminger2006-07-131-2/+2
| | | | | | | | | Patch to correct broken collision threshold mask in (same problem as sky2 driver). Should be three bits wide, but the mask only allows for 1 bit to be set. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] skge: transmit complete via IRQ not NAPIStephen Hemminger2006-06-081-0/+1
| | | | | | | | | The transmit side code has a number of ring problems that caused some of the Bugzilla reports. Rather than trying to fix the details, it is safer to rewrite the code that handles transmit completion and freeing.

* [PATCH] skge: use workq for PHY handlingStephen Hemminger2006-06-081-3/+2
| | | | | | | | Since accessing the PHY can take 100's of usecs, use a work queue to allow spinning in outside of soft/hard irq. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] skge: compute available ring buffersStephen Hemminger2006-03-231-1/+0
| | | | | | | | | Don't need to keep track of available buffers, it is simpler to just compute the value (ala e1000). Don't need tes on link up because should always have available buffers then. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] skge: use auto masking of irqsStephen Hemminger2006-03-211-1/+0
| | | | | | | | | Improve performance of skge driver by not touching irq mask register as much. Since the interrupt source auto-masks, the driver can just leave it disabled until the end of the soft irq. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* skge: protect interrupt maskStephen Hemminger2006-02-231-0/+1
| | | | | | | | There is a race between updating the irq mask and setting it which can be triggered on SMP with a bad cable. Similar patch from Ingo Molnar and Thomas Gleixner Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
* [PATCH] skge: get rid of Yukon2 definesStephen Hemminger2005-12-241-72/+1

* [PATCH] skge: clear PCI PHY COMA mode on bootStephen Hemminger2005-11-091-0/+2
| | | | | | | | When skge is booted up, the PHY may be stuck in power down state by the previous OS. So we may need to turn it on. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

* [PATCH] skge: stop bogus sensor messagesStephen Hemminger2005-08-161-2/+6
| | | | | | | | | | | | | | | Some versions of the Marvell yukon generate bogus sensor warning interrupts. The driver would flood log with these messages.

* [PATCH] skge: handle Tx/Rx arbiter timeoutStephen Hemminger2005-06-281-2/+5

| | | | | | | | | Rewrite the code for handling the Broadcom PHY to something that works. Remove link polling because Broadcom and Yukon don't need it. When I wrote initial code, didn't have a genesis chipset based board to test, so it was a non-working guess. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
