However,\nAVF driver schedule another reset due to notification, which causes two\nconcurrent reset going on, and trigger lock up in the FW, with AQ call to\ndelete VSI.\n\nSigned-off-by: Akeem G Abodunrin <akeem.g.abodunrin@intel.com>\n---\n drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c | 11 +++++++++--\n 1 file changed, 9 insertions(+), 2 deletions(-)", "diff": "diff --git a/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c b/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c\nindex 78fd3fa8ac8b..b93324e9f4bc 100644\n--- a/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c\n+++ b/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c\n@@ -1152,12 +1152,19 @@ static bool ice_reset_vf(struct ice_vf *vf, bool is_vflr)\n \tu32 reg;\n \tint i;\n \n-\t/* If the VFs have been disabled, this means something else is\n-\t * resetting the VF, so we shouldn't continue.\n+\t/* If the PF has been disabled, there is no need resetting VF until\n+\t * PF is active again.\n \t */\n \tif (test_bit(__ICE_VF_DIS, pf->state))\n \t\treturn false;\n \n+\t/* If the VF has been disabled, this means something else is\n+\t * resetting the VF, so we shouldn't continue.
