* sky2: don't look for VPD sizeStephen Hemminger2009-06-16
| | | | | | | | | | | | | | | | | | | The code to compute VPD size didn't handle some systems that use chip without VPD. Also some of the newer chips use some additional registers to store the actual size, and wasn't worth putting the additional complexity in, so just remove the code. No big loss since the code to set the VPD size was only a convenience so that utilities would not read the extra space past the end of the available VPD. Move the first PCI config read earlier to detect bad hardware where it returns all ones and refuse loading driver before furthur damage.

* net: dont update dev->trans_startEric Dumazet2009-05-29
| | | | | | | | | | | | | Second round of drivers for Gb cards (and NIU one I forgot in the 10GB round) Now that core network takes care of trans_start updates, dont do it in drivers themselves, if possible. Drivers can avoid one cache miss (on dev->trans_start) in their start_xmit() handler. Exceptions are NETIF_F_LLTX drivers Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

* [NET]: Fix drivers to handle napi_disable() disabling interrupts.David S. Miller2008-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we add the generic napi_disable_pending() breakout logic to net_rx_action() it means that napi_disable() can cause NAPI poll interrupt events to be disabled. And this is exactly what we want. If a napi_disable() is pending, and we are looping in the ->poll(), we want ->poll() event interrupts to stay disabled and we want to complete the NAPI poll ASAP. When ->poll() break out during device down was being handled on a per-driver basis, often these drivers would turn interrupts back on when '!netif_running()' was detected. And this would just cause a reschedule of the NAPI ->poll() in the interrupt handler before the napi_disable() could get in there and grab the NAPI_STATE_SCHED bit. The vast majority of drivers don't care if napi_disable() might have the side effect of disabling NAPI ->poll() event interrupts. In all such cases, when a napi_disable() is performed, the driver just disabled interrupts or is about to. However there were three exceptions to this in PCNET32, R8169, and SKY2. To fix those cases, at the subsequent napi_enable() points, I added code to ensure that the ->poll() interrupt events are enabled in the hardware. Signed-off-by: David S.

* sky2: RX lockup fixStephen Hemminger2007-12-14
| | | | | | | | | | | | | | | | | | | | | | | I'm using a Marvell 88E8062 on a custom PPC64 blade and ran into RX lockups while validating the sky2 driver. The receive MAC FIFO would become stuck during testing with high traffic. One port of the 88E8062 would lockup, while the other port remained functional. Re-inserting the sky2 module would not fix the problem - only a power cycle would. I looked over Marvell's most recent sk98lin driver and it looks like they had a "workaround" for the Yukon XL that the sky2 doesn't have yet. The sk98lin driver disables the RX MAC FIFO flush feature for all revisions of the Yukon XL. According to skgeinit.c of the sk98lin driver, "Flushing must be enabled (needed for ASF see dev. #4.29), but the flushing mask should be disabled (see dev. #4.115)". Nice. I implemented this same change in the sky2 driver and verified that the RX lockup I was seeing was resolved.

| | | | | | | | | | | | Prevent deadlock in sky2 recovery logic. sky2_down calls napi_synchronize which gets stuck if napi was already disabled.
