Applications which add RSS rules must supply an RSS key and length.
If an application is only interested in default RSS operation it
should not care about the exact RSS key.
By setting the key to NULL - the PMD will use the default RSS key.
In addition if the application does not care about the RSS type it can
set it to 0 and the PMD will use the default type (ETH_RSS_IP).

The last part of patchset contains the rule cleanup routines.
These ones is the part of outer interface initialization at
the moment of VXLAN VTEP attaching. These routines query
the list of attached VXLAN devices, the list of local IP
addresses with peer and link scope attribute and the list
of permanent neigh rules, then all found abovementioned
items on the specified outer device are flushed.

VXLAN encap rules are applied to the VF ingress traffic and have the
VTEP as actual redirection destinations instead of outer PF.
The encapsulation rule should provide:
- redirection action VF->PF
- VF port ID
- some inner network parameters (MACs/IP)
- the tunnel outer source IP (v4/v6)
- the tunnel outer destination IP (v4/v6). Current
- VNI - Virtual Network Identifier
There is no direct way found to provide kernel with all required
encapsulatioh header parameters. The encapsulation VTEP is created
attached to the outer interface and assumed as default path for
egress encapsulated traffic. The outer tunnel IP address are
assigned to interface using Netlink, the implicit route is
created like this:
ip addr add <src_ip> peer <dst_ip> dev <outer> scope link
Peer address provides implicit route, and scode link reduces
the risk of conflicts. At initialization time all local scope
link addresses are flushed from device (see next part of patchset).
The destination MAC address is provided via permenent neigh rule:
ip neigh add dev <outer> lladdr <dst_mac> to <dst_ip> nud permanent
At initialization time all neigh rules of this type are flushed
from device (see the next part of patchset).

VXLAN interfaces are dynamically created for each local UDP port
of outer networks and then used as targets for TC "flower" filters
in order to perform encapsulation. These VXLAN interfaces are
system-wide, the only one device with given UDP port can exist
in the system (the attempt of creating another device with the
same UDP local port returns EEXIST), so PMD should support the
shared device instances database for PMD instances. These VXLAN
implicitly created devices are called VTEPs (Virtual Tunnel
End Points).
Creation of the VTEP occurs at the moment of rule applying. The
link is set up, root ingress qdisc is also initialized.
Encapsulation VTEPs are created on per port basis, the single
VTEP is attached to the outer interface and is shared for all
encapsulation rules on this interface. The source UDP port is
automatically selected in range 30000-60000.
For decapsulaton one VTEP is created per every unique UDP
local port to accept tunnel traffic. The name of created
VTEP consists of prefix "vmlx_" and the number of UDP port in
decimal digits without leading zeros (vmlx_4789). The VTEP
can be preliminary created in the system before the launching
application, it allows to share UDP ports between primary
and secondary processes.

This patch adds VXLAN support for flow item/action lists validation.
The following entities are now supported:
- RTE_FLOW_ITEM_TYPE_VXLAN, contains the tunnel VNI
- RTE_FLOW_ACTION_TYPE_VXLAN_DECAP, if this action is specified
the items in the flow items list treated as outer network
parameters for tunnel outer header match. The ethernet layer
addresses always are treated as inner ones.
- RTE_FLOW_ACTION_TYPE_VXLAN_ENCAP, contains the item list to
build the encapsulation header. In current implementation the
values is the subject for some constraints:
- outer source MAC address will be always unconditionally
set to the one of MAC addresses of outer egress interface
- no way to specify source UDP port
- all abovementioned parameters are ignored if specified
in the rule, warning messages are sent to the log
Minimal tunneling support is also added. If VXLAN decapsulation
action is specified the ETH item can follow the VXLAN VNI item,
the content of this ETH item is treated as inner MAC addresses
and type. The outer ETH item for VXLAN decapsulation action
is always ignored.

If the multispeed fiber link is in DOWN state, ixgbe_setup_link

long time busy waiting on ixgbe_setup_link() for a DOWN fiber
ports. For case with 3 down ports it hangs for a 3 seconds and
unable to do anything including packet processing.
