If the tunnel port was not specified, the default one should be
configured to 4789 within the flow parser. Failure to do so will
result in a failed flow creation.

net/bnxt/tf_ulp: miscellaneous fixes

Template compiler modifications for v3 api:
Compile named/unnamed shared app resources for the applications
that are capable.

Change app id signature with base zero offset:
The app id is used in the calculation of the matching signatures
and as app id value increases the output of the signature also
increases to keep up the scale, the app id is reset to zero based
offset. Also fix some whitespace errors.

Add support for vxlan-gpe:
Add support for enabling UPAR1 and UPAR2 to parse vxlan-gpe/nsh/ipv4
and vxlan-gpe/nsh/ipv6 packets for.

Default parif handling for single port cards:
Update Ingress default and offloaded flows to use driver
function parif, instead of physical port parif. We have cards
that use single physical port with two PFs on the same physical
port, this causes the default physical port parif to be over
written by the second PF. If you use driver function parif then
single port with more than one PF can use its own parif and not
step on each other.

Note: We cannot support TWO VFs on the same PF, because driver
function parif is based on PF fw id, so if two VFs on same PF
are offloading flows they will get the same driver function parifs
and this will interfere with each other.

Support vxlan flow with vxlan-gpe port:
The patch adds the APP_CAP_CUST_VXLAN flag, so that the app
can create a custom vxlan flow, instead of vxlan-gpe flow,
when the custom vxlan port is 4790.

Synchronize async event handler and Truflow init:
If Truflow is not initialized then bail out in async event handler
gracefully. Add a new macro ulp_is_default_session_active().

Reduce the log level from info to debug:
Default VFR action record get api in templates that do not support
VFR report an info message which looks like an error. But it is benign
and doesn't impact the functionality. So change the log level to
debug from info.

Read upar_in_use from tunnel_dst_port_alloc response:
This patch reads the upar_in_use field from
hwrm_tunnel_dst_port_alloc's response and stores inside the bp
structure.

Add API to configure hot upgrade:
This patch adds an API that can be called to configure hot upgrade.
If this API is not called then the driver relies on the environment
variable to configure the hot upgrade feature.

Add parser changes to support custom VxLAN:
This patch writes UPAR1 tunnel header type to the computational
field at index VXLAN_IP_UPAR_ID.

Free custom vxlan tunnel port:
The current code invokes ulp_cust_vxlan_free() while detaching
a port from the session. This is incorrect since it should be freed
only when the session reference count goes to zero. So move this
to bnxt_ulp_deinit().

Parse UDP dport 4789 as VxLAN conditionally:
Currently, the ULP parser is parsing UDP dport 4789 as VxLAN
unconditionally. However for some apps, the requirement may be to
consider UDP dport 4789 as non-tunnel. This patch fixes the problem
by parsing UDP dport 4789 as non-tunnel when needed.

Delete flow context for the port being deleted:
Flow manager is running in alarm thread and the main thread is
deleting the flow context causing garbage data to request flow
count. Delete the ulp context before deleting the flows so
that flow manager thread does not dereference invalid ulp context.

Validate ulp context while parsing L4 proto type:
In ulp_rte_l4_proto_type_update() we try to access bp->ulp_ctx
without checking if it is valid. Add error checking and return
if ulp_ctx has not been initialized. Otherwise it could crash
the application.

Fix a crash seen in bnxt_ulp_port_init(), in some conditions:
The function bnxt_ulp_init() invokes ulp_ha_mgr_open() which
could fail in some conditions. As part of the error processing and
cleanup, bnxt_ulp_deinit() is called which frees ulp_ctx->cfg_data.
When the control returns back to bnxt_ulp_port_init(), as part of
its error handling it invokes ulp_cust_vxlan_free(). There we end
up dereferencing ulp_ctx->cfg_data which is already freed.
Fix this by updating the code (macro) to check for validity of
cfg_data before accessing it.

Support 256 vf representors:
Extend ULP port database size
Reduce Rx WC tcam slices from 6860 to 6572
Convert Rx VF rep default action record type from FULL to Compact

Set the correct vxlan or vxlan-gpe header type:
Appropriately configure the vxlan or vxlan_gpe header bit when an
application supports any customer vxlan port. The initial code
erroneously configures both vxlan and vxlan_gpe header bits when
adding a vxlan flow with the vxlan_gpe port(4790).
Remove endian converting code for port id.

Free L2 Etype tunnel for each port stop:
Update the point where ulp_l2_etype_tunnel_free() is called in
bnxt_ulp_port_deinit().
