From: Somnath Kotur <somnath.ko...@broadcom.com>
FW expects the driver to provide unique flow reference handles
for Tx or Rx flows. When a Tx flow and an Rx flow end up sharing
a reference handle, flow offload does not seem to work.
This could happen in the case of 2 flows having their L2 fields
wildcarded but in different direction.
Fix to incorporate the flow direction as part of the L2 key
Fixes: abd43a13525d ("bnxt_en: Support for 64-bit flow handle.")
