            Bug ID: 1817
           Summary: tx eventdev test fails if mbuf debug enabled
           Product: DPDK
           Version: 25.07
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: eventdev
          Assignee: dev@dpdk.org
          Reporter: stephen@networkplumber.org
  Target Milestone: ---

I built DPDK with MBUF debug enabled to test some other features.
When running the functional tests, discovered that Tx Evnetdev test fails.

EAL: Detected CPU lcores: 32
EAL: Detected NUMA nodes: 1
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket

APP: HPET is not enabled, using TSC as default timer

bad mbuf pool


Looks like the test is making bogus dummy mbufs and then expects to be able=
 to
safely transmit them. The test needs to be modified to use a normal mbuf po=
ol.
