[dpdk-stable] [PATCH v2 4/5] net/bnxt: fix non matching flow hitting filter rule

[Ajit Khaparde]

From: Santoshkumar Karanappa Rastapur <santosh.rastapur at broadcom.com>

As part of ntuple filter, we were creating L2 filter with the ntuple
redirect queue resulting in any L2 matching flow getting steered to
this queue. For ntuple filters, we need to create the L2 filter with
default queue. The user specified redirect queue will be set while
creating the ntuple filter in hardware.

Fixes: 5c1171c97216 ("net/bnxt: refactor filter/flow")
