As the only caller of dma_supported() outside of DMA API internals, the
qtfnmac driver stands out and invites scrutiny. Thankfully, it's not
being used for evil, but it is entirely redundant, since it open-codes a
check that the DMA mask setting functions are going to perform anyway.
In fact, the whole qtnf_pcie_init_dma_mask() function is nothing more
than a rather long-winded implementation of dma_set_mask_and_coherent(),
so let's just use that directly.

Previous patch removed the reliance on the counter in the FIB info to
set the offload indication, so we no longer need to keep an offload
state on each FIB entry and can just set or unset the RTNH_F_OFFLOAD
flag in each nexthop.
This is also necessary because we're going to need to refresh the
offload indication whenever the nexthop group associated with the FIB
entry is refreshed. Current check would prevent us from marking a newly
resolved nexthop as offloaded if the FIB entry is already marked as
offloaded.

This patch implements transparent fail over from synthetic NIC to
SR-IOV virtual function NIC in Hyper-V environment. It is a better
alternative to using bonding as is done now. Instead, the receive and
transmit fail over is done internally inside the driver.
Using bonding driver has lots of issues because it depends on the
script being run early enough in the boot process and with sufficient
information to make the association. This patch moves all that
functionality into the kernel.

For compile-testing purposes, we don't really need this anyway,
as CONFIG_OF can be enabled on all architectures, and HAS_IOMEM
is present on all architectures we do meaningful compile-testing on
