net/bnxt: modify VXLAN decap for multichannel mode

The driver is using physical port id as the index into
the tunnel inner flow table. However, this will not work in case
of multichannel mode where multiple physical functions are going
to share the same physical port id.

When tunnel inner flow offload request comes before tunnel
outer flow offload request, the driver caches the tunnel inner flow
details and programs it in the hardware after installing the tunnel
outer flow in the hardware. If more than one tunnel inner flow arrives
before tunnel outer flow is offloaded, the driver rejects any such
tunnel inner flow offload requests.

This patch fixes the above two problems by
1. Using dpdk port id as the index to store tunnel inner info.
2. Caching any number of tunnel inner flow offload requests that come
before offloading tunnel outer flow offload request

net/bnxt: support VXLAN decap offload

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.

net/bnxt: support representors on remote host domain

In the Stingray use case, representors are conventionally run
inside the SoC domain representing functions that are on the
X86 domain. In order to support this mechanism of building
representors for endpoints that are not in the same host domain,
additional dev args have been in the PMD like so:
rep-based-pf=<physical index> rep-is-pf=<VF=0 or PF=1>
where `rep-based-pf` specifies the physical index of the base PF
that the representor is derived off of.
Since representor(s) can be created for endpoint PFs as well,
rename struct bnxt_vf_representor to bnxt_representor and other such
dev_ops and function names.
devargs have also been extended to specify the exact CoS queue along
with flow control enablement to be used for the conduit between the
representor and the endpoint function.
This is how a sample devargs would look with all the extended devargs

-w 0000:06:02.0,host-based-truflow=1,representor=[1],rep-based-pf=8,
rep-is-pf=1,rep-q-r2f=1,rep-fc-r2f=0,rep-q-f2r=1,rep-fc-f2r=1

Call CFA_PAIR_ALLOC only in case of Stingray instead of CFA_VFR_ALLOC.
