* e1000: fix bug with shared interrupt during resetJesse Brandeburg2009-01-27
| | | | | | | | | | | | A nasty bug was found where an MTU change (or anything else that caused a reset) could race with the interrupt code. The interrupt code was entered by a shared interrupt during the MTU change. This change prevents the interrupt code from running while the driver is in the middle of its reset path.

* | netdevice: safe convert to netdev_priv() #part-2Wang Chen2008-11-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The call to e1000_clean_tx_irq in e1000_netpoll can race with the call to e1000_clean_tx_irq in e1000_clean.

This can result in multiple frees to the skbs on the tx ring buffer.

* e1000: Fix for 32 bits platforms with 64 bits resourcesBenjamin Herrenschmidt2008-02-11
| | | | | | | | | | | | | | | | | | | | The e1000 driver stores the content of the PCI resources into unsigned long's before ioremapping. This breaks on 32 bits platforms that support 64 bits MMIO resources such as ppc 44x. This fixes it by removing those temporary variables and passing directly the result of pci_resource_start/len to ioremap. The side effect is that I removed the assignments to the netdev fields mem_start, mem_end and base_addr, which are totally useless for PCI devices.

| | | | | | | | | | | | | | | | | Both the old e1000 driver and the new e1000e driver can drive some PCI-Express e1000 cards, and we should avoid ambiguity about which driver will pick up the support for those cards when both drivers are enabled. This solves the problem by having the old driver support those cards if the new driver isn't configured, but otherwise ceding support for PCI Express versions of the e1000 chipset to the newer driver. Thus allowing both legacy configurations where only the old driver is active (and handles all chips it knows about) and the new configuration with the new driver handling the more modern PCIE variants.
