Add a new ethtool operation (get_rxfh_indir_size) to get the
indirectional table size.  Use this to validate the user buffer size
before calling get_rxfh_indir or set_rxfh_indir.  Use get_rxnfc to get
the number of RX rings, and validate the contents of the new
indirection table before calling set_rxfh_indir.  Remove this
validation from drivers.

The vmxnet3 driver enables vlan filters if filtering is enabled for
any vlan.  In promiscuous mode the filter table is cleared to in
order to disable filtering.  However, if a vlan device is subsequently
created that vlan will be added to the filter, re-engaging it.  As a
result, not only do we not see all the vlans in promiscuous mode, we
don't even see vlans for which a filter was previously created.

Parent device for netdev should be set before netdev_info() can be called
otherwise there is a NULL pointer dereference and probe() fails.

vmxnet3 device supports only power-of-two number of queues. The driver
therefore needs to check this and rounds down the number of queues to the
nearest power of two.

If the rx ring is completely empty, then the device may never fire an rx
interrupt. Unfortunately, the rx interrupt is what triggers populating the
rx ring with fresh buffers, so this will cause networking to lock up.

This patch replenishes the skb in recv descriptor as soon as it is
peeled off while processing rx completions. If the skb/buffer
allocation fails, existing one is recycled and the packet in hand is
dropped. This way none of the RX desc is ever left empty, thus avoiding
starvation

When receiving packets from another guest on the same hypervisor, it's
generally possible to receive large packets because no segmentation is
necessary and these packets are handled by LRO.  However, when doing
routing or bridging we must disable LRO and lose this benefit.  In
these cases GRO can still be used and it is very effective because the
packets which are segmented in the hypervisor are received very close
together and can easily be merged.

This converts the vmxnet3 driver to use the new vlan model.  In doing so
it fixes missing tags in tcpdump and failure to do checksum offload when
tx vlan offload is disabled.
