netvsc: minor fixes and improvements

These are non-critical bug fixes, related to functionality now in net-next.
 1. delaying the automatic bring up of VF device to allow udev to change name.
 2. performance improvement
 3. handle MAC address change with VF; mostly propogate the error that VF gives.
 4. minor cleanups
 5. allow setting send/receive buffer size with ethtool.

Add ethtool statistics for case where send chimmeny buffer is
exhausted and driver has to fall back to doing scatter/gather
send. Also, add statistic for case where ring buffer is full and
receive completions are delayed.

Control the size of the buffer areas via ethtool ring settings.
They aren't really traditional hardware rings, but host API breaks
receive and send buffer into chunks. The final size of the chunks are
controlled by the host.

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.

The send and receive buffers are both per-device (not per-channel).
The associated NUMA node is a property of the CPU which is per-channel
therefore it makes no sense to force the receive/send buffer to be
allocated on a particular node (since it is a shared resource).

If VF is slaved to synthetic device, then any change to netvsc
MAC address should be propagated to the slave device.

If slave device doesn't support MAC address change then it
should also be an error to attempt to change synthetic NIC MAC
address.

It also fixes the error unwind in the original code.
If give a bad address, the old code would change the device
MAC address anyway.

net: sched: let the offloader decide what to offload

Currently there is a Qdisc_class_ops->tcf_cl_offload callback
that is called to find out if cls would offload rule or not.
This is only supported by sch_ingress and sch_clsact.
So the Qdisc are to decide. However, the driver knows what is he
able to offload, so move the decision making to drivers completely.
Just pass classid there and provide set of helpers to allow
identification of qdisc.

As a side effect, this actually allows clsact egress rules
offload in mlxsw.

sctp: remove typedefs from structures part 6

As we know, typedef is suggested not to use in kernel, even checkpatch.pl
also gives warnings about it. Now sctp is using it for many structures.

All this kind of typedef's using should be removed. This patchset is the
part 6 to remove all typedefs in include/net/sctp/structs.h, command.h
and sm.h.

Just as the part 1-5, No any code's logic would be changed in these patches,
only cleaning up.

Note that this is the last part for this typedef cleaning up. after this
patchset, no more inappropriate typedefs in sctp. It's also to tidy some
codes when removing them, like fixing many indents, reodering some local
params, especially in the last 2 patches.

There are some bad indents of functions' defination in sm_make_chunk.c.
They have been there since beginning, it was probably caused by that
the typedef sctp_chunk_t was replaced with struct sctp_chunk.

So it's the best time to fix them in this patchset, it's also to fix
some bad indents in other functions' defination in sm_make_chunk.c.
