Subject: net/bnxt: reset filter indices on free
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=7105de7085b022a84ffefbfad6a140e493ee0612

net/bnxt: reset filter indices on free

Fix bnxt_free_filter() to ensure that the filter indices
are reset correctly when a filter is freed.

This change helps in avoiding few duplicate code as well.
