            Bug ID: 1958
           Summary: Broadcom bnxt RTE_ETH_TX_OFFLOAD_MBUF_FAST_FREE always
                    on
           Product: DPDK
           Version: 26.03
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev at dpdk.org
          Reporter: riaan.wiid at vastech.co.za
  Target Milestone: ---

Environment
===========

dpdk-26.03 (tag v26.03)
OS: Rocky Linux (9.3 (Blue Onyx))
HW: Broadcom BCM57414 NetXtreme-E 10Gb/25Gb
Compiler: gcc 14.2.1 20240801 (Red Hat 14.2.1-1)

Description of Problem
======================

RTE_ETH_TX_OFFLOAD_MBUF_FAST_FREE is always enabled if not enabling PTP support
on a NIC port. In our case we are not enabling PTP support which means
RTE_ETH_TX_OFFLOAD_MBUF_FAST_FREE is enabled by default on all queues, which is
undesired behaviour when making use of Mbuf refcnt in our designs.

This behaviour seems to have started after this commit
https://github.com/DPDK/dpdk/commit/5722ed1aafd2fc5ad44e432a4f6c7bd337c673d8

RTE_ETH_TX_OFFLOAD_MBUF_FAST_FREE cannot be disabled through the offloads
specified in either rte_eth_dev_configure() or rte_eth_tx_queue_setup()
