net/bnxt: add enhancements to TruFlow ULP

1. Added support to specify l4 port masks in the template. Also enabled
   source mac in the wild card key for ingress flows.

2. Added support to enable offload for ipv6 traffic within the vxlan
   tunnel connection.

3. The flow counters is reduced from 7168 to 6912 for Whitney.
   The stats operation is updated to reflect counts for packets
   at egress from CFA instead of ingress to CFA

4. The miss path for the l2 context table is updated with correct
   parif and default action handler to handle the miss path for
   egress flows.

5. This support enables allocation of encapsulation, modification and
   action records dynamically based on a given flow actions.

6. Reduce the l2context resource requests during open_session. Move the
   SMAC from the L2Context to the EM/WM

7. Remap the parif in the bd action in order to eliminate incorrect
   replication of broadcast packets. The layer 4 source port mask
   was incorrectly updated in the outer layer 4 source port mask
   instead of inner layer 4. Add the l3 proto to egress rules, switch
   to using computed fields for l4 ports, add internal smac to f1/f2
   flows, add l3 proto to ingress ipv6 flows
