Subject: distributor: fix scalar matching
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=626ceefbf4e1786ded4fed6a4987e3f1d370e9c0;p=dpdk.git

distributor: fix scalar matching

Fix improper indexes while comparing tags.
In the find_match_scalar() function:
* j iterates over flow tags of following packets;
* w iterates over backlog or in flight tags positions.

Fixes: 775003ad2f96 ("distributor: add new burst-capable library")
