When using the device emulation feature (introduced in Bluefield-1 SOC),
a privileged function (the device emulation manager) will be able to
create a channel to execute commands on behalf of the emulated function.

This channel will be a general object of type VHCA_TUNNEL that will have
a unique ID for each emulated function. This ID will be passed in each
cmd that will be issued by the emulation SW in a well known offset in
the command header.

This channel is needed since the emulated function doesn't have a normal
command interface to the HCA HW, but some basic configuration for that
function is needed (e.g. initialize and enable the HCA). For that matter,
a specific command-set was defined and only those commands will be issued

When ECPF eswitch manager is at offloads mode, it monitors functions
changed event from host PF side and acts according to the number of
VFs enabled/disabled.

As ECPF and host PF work in two independent hosts, it's possible that
host PF OS reboots but ECPF system is still kept on and continues
monitoring events from host PF. When kernel from host PF side is
booting, PCI iov driver does sriov_init and compute_max_vf_buses by
iterating over all valid num of VFs. This triggers FLR and generates
functions changed events, even though host PF HCA is not enabled at
this time. However, ECPF is not aware of this information, and still
handles these events as usual. ECPF system will see massive number of
reps are created, but destroyed immediately once creation finished.

To eliminate this noise, a bit is added to host parameter context to
indicate host PF is disabled. ECPF will not handle the VF changed
event if this bit is set.

Since the structure is never written to, we can statically allocate

subsequent function arguments that we pass it into as 'const'

While FW has no idea about what it is in the metadata, a syndrome will

in flow_source, the same default value as before, as a pre-step towards
metadata matching for fast path.

When a dual-port VHCA sends a RoCE packet on its non-native port, and the
packet arrives to its affiliated vport FDB, a mismatch might occur on the
rules that match the packet source vport as it is not represented by single
VHCA only in this case. So we change to match on metadata instead of source
vport.
To do that, a rule is created in all vports and uplink ingress ACLs, to
save the source vport number and vhca id in the packet's metadata in order
to match on it later.
The metadata register used is the first of the 32-bit type C registers. It
can be used for matching and header modify operations. The higher 16 bits
of this register are for vhca id, and the lower 16 ones is for vport
number.
This change is not for dual-port RoCE only. If HW and FW allow, the vport
metadata matching is enabled by default.
