      What were you trying to do that didn't work?

      When keep reloading mana_ib mana drivers(e.g. 100 times), sometimes see error -71 and error -110:

      [  526.952946] mana 7870:00:00.0: Microsoft Azure Network Adapter protocol version: 0.1.1
      [  557.152888] mana 7870:00:00.0: test_eq timed out on queue 0
      [  557.154551] mana 7870:00:00.0: Failed to create EQ: -71
      [  557.183196] mana 7870:00:00.0: gdma probe failed: err = -71
      [  557.186091] mana: probe of 7870:00:00.0 failed with error -71  
      [ 1529.536653] mana 7870:00:00.0: Failed to establish HWC: -110
      [ 1529.548191] mana 7870:00:00.0: gdma probe failed: err = -110
      [ 1529.549869] mana 7870:00:00.0: probe with driver mana failed with error -110
      [ 1529.564140] mana_ib: unknown parameter 'mana' ignored 
      

      What is the impact of this issue to you?

      1. See error message
      2. After some errors occur, mana driver status is incorrect.

      Please provide the package NVR for which the bug is seen:

      kernel-5.14.0-570.4.1.el9_6.x86_64

      kernel-5.14.0-570.6.1.3597_1727238351.el9_6.x86_64 (RHEL-82687)

      How reproducible is this bug?:

      1~10%

      Steps to reproduce

      1.  Create a D2s_v6 size VM on Azure. lspci check MANA NIC exists.
      2.  Keep reloading mana driver for multiple times(e.g. 1000 times)
      3.  Check dmesg

      Expected results

      No error found

      Actual results

      Can see error -71 and error -110. Sometimes the mana driver is loaded(lsmod|grep mana) but cannot see VF NIC in ip addr.
