Drivers that initiate roaming while being connected to a network that
uses 802.1X authentication need to inform user space if 802.1X
authentication is further required after roaming.
For example, when using the Fast transition protocol, roaming within
the mobility domain does not require new 802.1X authentication, but
roaming to another mobility domain does.
In addition, some drivers may not support 802.1X authentication
(so it has to be done in user space), while other drivers do.
Add a flag to the roaming notification to indicate if user space is
required to do 802.1X authentication after the roaming or not.
This flag will only be used for networks that use 802.1X
authentication. For networks that do not use 802.1X authentication it
is assumed that no further action is required from user space after
the roaming notification.

Let drivers advertise support for station-mode 4-way handshake
offloading with a new NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_PSK flag.
Extend use of NL80211_ATTR_PMK attribute indicating it might be passed
as part of NL80211_CMD_CONNECT command, and contain the PSK (which is
the PMK, hence the name.)
The driver/device is assumed to handle the 4-way handshake by
itself in this case (including key derivations, etc.), instead
of relying on the supplicant.

Instead of using the SKB queue with the fake pkt_type for the
offloaded RX BA session management, also handle this with the
normal aggregation state machine worker. This also makes the
use of this more reliable since it gets rid of the allocation
of the fake skb.
Combined with the previous patch, this finally allows us to
get rid of the pkt_type hack entirely, so do that as well.

mlx4 drivers: version update
This patchset contains version updates for the MLX4 drivers:
Core, EN, and IB.
Just like we've done in mlx5, we modify the outdated driver
version (reported in ethtool for example).
This better reflects the current driver state, and removes the
redundant date string.
We are not going to change this frequently or even use it.
I include the IB patch in this series as it has similar subject
and content.
It does not cause any kind of conflict with Doug's tree.
The rdma mailing list is CCed.
Please let me know if I need to submit this differently.

nfp: ctrl vNIC
This series adds the ability to use one vNIC as a control channel
for passing messages to and from the application firmware. The
implementation restructures the existing netdev vNIC code to be able
to deal with nfp_nets with netdev pointer set to NULL. Control vNICs
are not visible to userspace (other than for dumping ring state), and
since they don't have netdevs we use a tasklet for RX and simple skb
list for TX queuing.
Due to special status of the control vNIC we have to reshuffle the
init code a bit to make sure control vNIC will be fully brought up
(and therefore communication with app FW can happen) before any netdev
or port is visible to user space.
FW will designate which vNIC is supposed to be used as control one
by setting _pf%u_net_ctrl_bar symbol. Some FWs depend on metadata
being prepended to control message, some prefer to look at queue ID
to decide that something is a control message. Our implementation
can cater to both.
First two users of this code will be eBPF maps and flower offloads.

NFD ABI 0.5 is equivalent to NFD ABI 3.0 but requires that the
driver checks the APP id symbol and makes sure it can support
given app. Most advanced apps will likely require control vNIC
(ability to exchange control messages between the driver and
app FW). Detailed app version checking and capability exchange
is left to app-specific code.

We want to be able to create a special vNIC for control messages.
This vNIC should be created before any netdev is registered to allow
nfp_app logic to exchange messages with the FW app before any netdev
is visible to user space. Unfortunately we can't enable IRQs until
we know how many vNICs we will need to spawn.
Divide the function which spawns netdevs for vNICs into three parts:
- vNIC/memory allocation;
- IRQ allocation;
- netdev init and register.
This will help us insert the initialization of the control channel
after IRQ allocation but before netdev init and register.

Reading fw version from the BAR is trivial. Don't pass it around
through layers of init functions, simply read it again where needed.
This commit has the side effect of each vNIC having the exact NFD
version from its own control memory, rather than all data vNICs
assuming the version of the first one. This should not result in
user-visible changes, though. Capabilities of data vNICs of trival
apps are identical.
