This patch is similar to earlier vxlan patch.
Geneve device close operation frees geneve socket. This
operation can race with geneve-xmit function which
dereferences geneve socket. Following patch uses RCU
mechanism to avoid this situation.

Driver allocates a shadow array for transmitted SKBs with X entries;
That means valid indices are {0,...,X - 1}. [X == 8191]
Problem is the driver also uses X as a mask for a
producer/consumer in order to choose the right entry in the
array which allows access to entry X which is out of bounds.

To fix this, simply allocate X + 1 entries in the shadow array.

<title>enic: fix rq disable</title>

<id>9fe1c98ac90023842ae7cd921badfa1029e45bd1</id>
<content type='text'>
When MTU is changed from 9000 to 1500 while there is burst of inbound 9000
bytes packets, adaptor sometimes delivers 9000 bytes packets to 1500 bytes
buffers. This causes memory corruption and sometimes crash.

This is because of a race condition in adaptor between "RQ disable"
clearing descriptor mini-cache and mini-cache valid bit being set by
completion of descriptor fetch. This can result in stale RQ desc being
cached and used when packets arrive. In this case, the stale descriptor
have old MTU value.

Solution is to write RQ-&gt;disable twice. The first write will stop any
further desc fetches, allowing the second disable to clear the mini-cache
valid bit without danger of a race.

Also, the check for rq-&gt;running becoming 0 after writing rq-&gt;enable to 0
is not done properly. When incoming packets are flooding the interface,
rq-&gt;running will pulse high for each dropped packet. Since the driver was
waiting for 10us between each poll, it is possible to see rq-&gt;running = 1
1000 times in a row, even though it is not actually stuck running.
This results in false failure of vnic_rq_disable(). Fix is to try more
than 1000 time without delay between polls to ensure we do not miss when
running goes low.

In old adaptors rq-&gt;enable needs to be re-written to 0 when posted_index
is reset in vnic_rq_clean() in order to keep rq-&gt;prefetch_index in sync.

====================
Intel Wired LAN Driver Updates 2016-10-27

This series contains fixes to ixgbe and i40e.

Emil fixes a NULL pointer dereference when a macvlan interface is brought
up while the PF is still down.

David root caused the original panic that was fixed by commit id
(a036244c068612 "i40e: Fix kernel panic on enable/disable LLDP") and the
fix was not quite correct, so removed the get_default_tc() and replaced
it with a #define since there is only one TC supported as a default.

Guilherme Piccoli fixes an issue where if we modprobe the driver module
without enough MSI-X interrupts, then unload the module and reload it
again, the kernel would crash.  So if we fail to allocate enough MSI-X
interrupts, we should disable them since they were previously enabled.

Huaibin Wang found that the order of the arguments for
ndo_dflt_bridge_getlink() were in the correct order, so fix the order.
