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.

Due to the fact that skb_dma_map/unmap do not work correctly when a HW
IOMMU is enabled it has been recommended to go about removing the calls
from the network device drivers.

This patch removes the skb_dma_map/unmap calls from the igbvf driver due to

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.

skb_dma_map is incompatible with HW iommu due to the fact that multiple
mappings can result in different results each time. For this reason it is
best to just remove use of these function calls.

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.

Every time while doing ethtool->get_settings we are accessing

This is not necessary. We now use the cached copy for this info
and update it when the link status changes.

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.

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. Also make sure attempts to access these
