In case of delete/update switch rule, > admin command can return ICE_AQ_RC_ENOENT error code if such rule does > not exist, hence return ICE_ERR_DOES_NOT_EXIST error code from > ice_aq_sw_rule, so that caller of this function can decide how to handle > ICE_ERR_DOES_NOT_EXIST. > > Signed-off-by: Kiran Patil <kiran.patil@intel.com> > --- > drivers/net/ethernet/intel/ice/ice_switch.c | 8 +++++++- > 1 file changed, 7 insertions(+), 1 deletion(-) Tested-by: Andrew Bowers <andrewx.bowers@intel.com>
