When receiving packets, netvsp puts data in a buffer mapped through UIO.
Depending on packet size, netvsc may attach the buffer as an external
mbuf. This is not a problem if this mbuf is consumed in the application,
and the application can correctly read data out of an external mbuf.
However, there are two problems with data in an external mbuf.
1. Due to the limitation of the kernel UIO implementation, physical
address of this external buffer is not exposed to the user-mode. If
this mbuf is passed to another driver, the other driver is unable to
map this buffer to iova.
2. Some DPDK applications are not aware of external mbuf, and may bug
when they receive an mbuf with external buffer attached.
Introduce a driver parameter "rx_extmbuf_enable" to control if netvsc
should use external mbuf for receiving packets. The default value is 0.
(netvsc doesn't use external mbuf, it always allocates mbuf and copy
data to mbuf) A non-zero value tells netvsc to attach external buffers
to mbuf on receiving packets, thus avoid copying memory.

The values for Rx and Tx copy break should be tunable rather
than hard coded constants.
The rx_copybreak sets the threshold where the driver uses an
external mbuf to avoid having to copy data. Setting 0 for copybreak
will cause driver to always create an external mbuf. Setting
a value greater than the MTU would prevent it from ever making
an external mbuf and always copy. The default value is 256 (bytes).
Likewise the tx_copybreak sets the threshold where the driver
aggregates multiple small packets into one request. If tx_copybreak
is 0 then each packet goes as a VMBus request (no copying).
If tx_copybreak is set larger than the MTU, then all packets smaller
than the chunk size of the VMBus send buffer will be copied; larger
packets always have to go as a single direct request. The default
value is 512 (bytes).

Enable metadata extraction for flexible descriptors in AVF, that would
allow network function directly get metadata without additional parsing
which would reduce the CPU cost for VFs. The enabling metadata
extractions involve the metadata of VLAN/IPv4/IPv6/IPv6-FLOW/TCP/MPLS
flexible descriptors, and the VF could negotiate the capability of
the flexible descriptor with PF and correspondingly configure the
specific offload at receiving queues.

VXLAN decap offload can happen in stages. The offload request may
not come as a single flow request rather may come as two flow offload
requests F1 & F2. This patch is adding support for this two stage
offload design. The match criteria for F1 is O_DMAC, O_SMAC,
O_DST_IP, O_UDP_DPORT and actions are COUNT, MARK, JUMP. The match
criteria for F2 is O_SRC_IP, O_DST_IP, VNI and inner header fields.
F1 and F2 flow offload requests can come in any order. If F2 flow
offload request comes first then F2 can’t be offloaded as there is
no O_DMAC information in F2. In this case, F2 will be deferred until
F1 flow offload request arrives. When F1 flow offload request is
received it will have O_DMAC information. Using F1’s O_DMAC, driver
creates an L2 context entry in the hardware as part of offloading F1.
F2 will now use F1’s O_DMAC to get the L2 context id associated with
this O_DMAC and other flow fields that are cached already at the time
of deferring F2 for offloading. F2s that arrive after F1 is offloaded
will be directly programmed and not cached.

- restore outer header of partially offloaded packet;
- model is implemented as a set of helper functions.
Implementation details:
* tunnel_offload PMD parameter must be set to 1 to enable the feature.
* application cannot use MARK and META flow actions with tunnel.
* offload JUMP action is restricted to steering tunnel rule only.
