Some function pointers for a few PHY operations (for 82578 and 82567) and were set incorrectly causing functions to be executed that were accessing incorrect PHY register offsets for that particular device. This patch also moves a few PHY-specific functions from ich8lan.c to the more appropriate phy.c.

The workaround that detects the correct PHY ID when an initial read of the PHY ID registers returns an invalid one should retry up to ten times with a small delay between attempts using a single PHY address and then repeat using the remaining possible PHY addresses. Do this instead of trying each possible PHY address repeating that up to 100 times.

The function pointers for 8257x devices are not set. This is not really a problem now because there is nothing in the driver that references the pointers for this particular MAC-family (the appropriate functions are called directly), but the pointers should be set in case they are used in the future.

The two functions skb_dma_map/unmap are unsafe to use as they cause problems when packets are cloned and sent to multiple devices while a HW IOMMU is enabled. Due to this it is best to remove the code so it is not used by any other network driver maintainters.

This change removes skb_dma_map/unmap calls from the igb driver due to the fact that the call is incompatible with iommu enabled kernels. In order to prevent warnings about using the wrong unmap call I have added a mapped_as_page value to the buffer_info structure to track if the mapped region is a page or a buffer.

This patch removes skb_dma_map/unmap calls from the ixgbe driver due to the fact that the calls don't work with HW IOMMU enabled systems. The problem is that multiple mappings will give different results when HW IOMMU is enabled and the skb_dma_map/unmap calls only have one location to store mappings.

In testing we have found that skb_dma_map/unmap is incompatible with HW IOMMU due to the fact that multiple mappings will return different results. In order to correct this we need to remove skb_dma_map/unmap calls from the e1000e driver.

This new PCI device ID is for a new combination of MAC and PHY both of which already have supporting code in the driver, just not yet in this combination. During validation of the device, an intermittent issue was discovered with waking it from a suspended state which can be resolved with the pre-existing workaround to disable gigabit speed prior to suspending.

The different families (80003es2lan, 8257x, ICHx/PCH) supported by the driver each have their own conditions when the PHY can be powered down. This patch rewrites the PHY power up/down code to fit with the family- specific style used in the driver. All pre-existing calls to power up or down the PHY remain untouched. A new call to power down the PHY when removing the driver when the interface is down replaces the current call to reset the PHY in order to reduce power consumption.

The two MAC-families that have VLAN filter table register arrays manage each a bit differently from one another, so provide family-specific functions for managing the register arrays and function pointers to access the appropriate function.
