[PATCH 30/47] net/bnxt: tf_ulp: add mask defaults when mask is not specified

[Sriharsha Basavapatna <sriharsha.basavapatna@broadcom.com>]

From: Kishore Padmanabha <kishore.padmanabha@broadcom.com>

If application does not specify mask in a field description then
use the default mask values from dpdk header files.

This patch also includes the following related changes.

fix stats collection for shared session
	The stats accumulation was being performed on default session,
	it needs to get the correct session type to get shared session
	counters.

updated ulp flow db for 64 bit handles
	Updated the ulp flow database so that all the hardware handles
	are 64 bit for all the resource types.

Template rejection with no tables fails for vf to vf
	Fixed the template rejection logic to include the table even on
	unconditional rejection.  This was exposed for vf to vf traffic on
	Thor 2 and resulted in a segmentation fault.

fix spec and default mask parsing for flow items.
	Fixed the protocol header parsing when bith spec and mask are
	not given.

Thor2 priority for l2 tcam records not adhered to
	Fix l2 context records priority in template compiler
	Fix flow handle mask offset
	Fix cpu_to_le_16 macro issues
	Fix misspellings in code
