[dpdk-dev] [PATCH v2 20/23] net/bnxt: fix to move a flow to a different queue

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

From: Somnath Kotur <somnath.kotur@broadcom.com>

While moving a flow to a different destination queue,
the l2_filter_id being passed to the FW command was incorrect.
Fix it by re-using the matching filter's l2_filter_id since
that is supposed to be the same in this case.

Fixes: 5ef3b79fdfe6 ("net/bnxt: support flow filter ops")
