If/when a generally agreed-upon way to control carrier on/off in the emulator/hypervisor level emerges, it will be trivial to extend the driver to support that too, but for now even this 2-liner makes user experience that much better.

This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet. Signed-off-by: Steve Glendinning Signed-off-by: David S.

It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag.

Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected.
