            Bug ID: 531
           Summary: ACL (librte_acl) Fails to match source ports
           Product: DPDK
           Version: 19.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: other
          Assignee: dev at dpdk.org
          Reporter: itamar.shoshani at ibm.com
  Target Milestone: ---

After upgrading to DPDK 19.11.3, one of our regression tests failed.
A simplified version of the test that still fails is:
    Creating a ruleset with two rules:
        - drop udp packet with a range of source ports
        - allow all udp traffic
    Sending udp packet with source port outside the range
We expect the packet to be forwarded but it drops.

A workaround that work for us was replacing lib/librte_acl/acl_bld.c with the
same file from DPDK 18.11.2.
