The field in hfa384x_ps_user_count was defined as u16 but used as __le16
Changed type to __le16 for consistency

Functions working with attribute_groups provided by
work with const attribute_group. These attribute_group structures do not
change at runtime so mark them as const.

Optimize how receive completion ring are managed.
* Allocate only as many slots as needed for all buffers from host
* Allocate before setting up sub channel for better error detection
* Don't need to keep copy of initial receive section message
* Only needt keep the transaction id, stat
The default value of send and receive buffer area for host DMA
is much larger than it needs to be. Experimentation shows that
4M receive and 1M send is sufficient.
Make the size a module parameter so that it can be adjusted
as needed for testing or special needs.

This includes a bunch of fixups for issues reported by sparse and
lockdep.
* ethtool routines can assume RTNL
* send is done with RCU lock (and BH disable)
Most of the changes involve passing internal device struct (netvsc)
as parameter, so that code called in both initialization and changes
Latency improvement related to NAPI conversion.
If all packets are processed from receive ring then need
to signal host.

The first two are more fixes to problems introduced in
latest net-next changes. The rest are changes to improve performance
and reduce memory footprint. The driver used to allocate large
amounts of memory (33M) per interface, this reduces that down to
about 7M.

Instead of just shutting up checkpatch, how about
restructuring the code a bit by adding a helper function
to this very long cvm_oct_poll?

The vboxvideo code uses various gen_pool_* functions, so it needs
lib/genalloc.c to be built. In some configs this is not happening,
so add select GENERIC_ALLOCATOR to the Kconfig file to enforce this.
Note all other Kconfig references to GENERIC_ALLOCATOR also use select.
