RFC 3635 helps also here to define properties of an Ethernet-like interface.
It's not so as crucial to follow RFC terms and definitions here as it's with
counters, but we can use it as a guide line. Addresses and promisc mode are
classification issues. Name and pktio status (stopped / started) ( ==
ifAdminStatus) are pktio level data.
typedef struct odp_pktio_link_state_t {
uint8_t type; // 0: Ethernet (or enum ODP_PKTIO_ETHERNET), ...
uint8_t status; // 1: link up, 0: down, -1 not_present (==
ifOperStatus )
uint8_t autoneg; // 1: autoneg on, 0: off, -1: not supported
uint8_t duplex; // 1: full duplex, 0: half duplex
uint32_t speed_mbps; // Speed in Mbps. This leaves room for
// speed_bps which would support odd (Mbps)
link speeds
uint32_t mtu; // MTU in bytes
} odp_pktio_link_state_t;
Better to use int (uint8_t) than bool to enable extendable status definitions.
E.g. ifOperStatus == not_present means that some HW component is missing,
rather than user have configured link down.
