    "content": "From: Steve Yang <stevex.yang@intel.com>\n\nCurrently, VF can only handle virtchnl event message by calling interrupt.\nIt is not available in two cases:\n1. If the event message comes during VF initialization before interrupt\nis enabled, this message will not be handled correctly.\n2. Some virtchnl commands need to receive the event message and handle\nit with interrupt disabled.\nTo solve this issue, we add the virtchnl event message handling in the\nprocess of reading vitchnl messages in adminq from PF.\n\nSigned-off-by: Steve Yang <stevex.yang@intel.com>\nSigned-off-by: Kevin Liu <kevinx.liu@intel.com>\n---\n drivers/net/ice/ice_dcf.c | 25 +++++++++++++++++++++++--\n 1 file changed, 23 insertions(+), 2 deletions(-)",
