General doubt I have , I see all IF-MIB and Ether-Like-MIB attributes are a= dded as Xstats. But most of IF-MIB attributes are not stats, instead they are information = about the interface/port. So I guess such attributes should be displayed using separate method? Eve= rything being displayed as xstats might not be correct. diff --git a/drivers/net/e1000/e1000_ethdev.h b/drivers/net/e1000/e1000_eth= dev.h index 8352d0a..d242990 100644 --- a/drivers/net/e1000/e1000_ethdev.h +++ b/drivers/net/e1000/e1000_ethdev.h @@ -254,6 +254,62 @@ struct e1000_filter_info { struct e1000_2tuple_filter_list twotuple_list; }; =20 +#define E1000_MIB_IF_TYPE_ETHERNETCSMACD 6 + +enum e1000_mib_truth_value { + e1000_mib_truth_true =3D 1, + e1000_mib_truth_false +}; 1)All enums should be in capital as per coding guidelines.
