Currently which bits we use is arbitrary since jhash

But soon we'll be using universal hashing functions,

In certain circumstances, like WoWLAN scenarios,

In order to successfully go through GTK rekeying,

Add API to let the supplicant hand the parameters
to the driver which may store it for future GTK
rekey operations.

Note that, of course, if GTK rekeying is done by
the device, the EAP frame must not be passed up
to userspace, instead a rekey event needs to be

dcbnl: Add CEE notification

This patch add an unsolicited notification of the DCBX negotiated
parameters for the CEE flavor of the DCBX protocol. The notification
message is identical to the aggregated CEE get operation and holds all
the pertinent local and peer information. The notification routine is
exported so it can be invoked by drivers supporting an embedded DCBX
stack.

dcbnl: Aggregated CEE GET operation

The following couple of patches add dcbnl an unsolicited notification of
the the DCB configuration for the CEE flavor of the DCBX protocol. This
is useful when the user-mode DCB client is not responsible for
conducting and resolving the DCBX negotiation (either because the DCBX
stack is embedded in the HW or the negotiation is handled by another
agent in the host), but still needs to get the negotiated parameters.
This functionality already exists for the IEEE flavor of the DCBX
protocol and these patches add it to the older CEE flavor.

The first patch extends the CEE attribute GET operation to include not
only the peer information, but also all the pertinent local
configuration (negotiated parameters). The second patch adds and export
a CEE specific notification routine.

packet: Add fanout support.

Fanouts allow packet capturing to be demuxed to a set of AF_PACKET
sockets.  Two fanout policies are implemented:

1) Hashing based upon skb->rxhash

2) Pure round-robin

An AF_PACKET socket must be fully bound before it tries to add itself
to a fanout.  All AF_PACKET sockets trying to join the same fanout
must all have the same bind settings.

Fanouts are identified (within a network namespace) by a 16-bit ID.
The first socket to try to add itself to a fanout with a particular
ID, creates that fanout.  When the last socket leaves the fanout
(which happens only when the socket is closed), that fanout is
destroyed.

vmxnet3: fix starving rx ring whenoc_skb kb fails

If the rx ring is completely empty, then the device may never fire an rx
