Function Documentation

netdev_eth_get()

int netdev_eth_get	(	netdev_t *	dev,
		netopt_t	opt,
		void *	value,
		size_t	max_len
	)

Fallback function for netdev ethernet devices' _get function.

Supposed to be used by netdev drivers as default case.

Warning

Driver MUST implement NETOPT_ADDRESS case!

Parameters

[in]	dev	network device descriptor
[in]	opt	option type
[out]	value	pointer to store the option's value in
[in]	max_len	maximal amount of byte that fit into value

Returns

number of bytes written to value

<0 on error

netdev_eth_set()

int netdev_eth_set	(	netdev_t *	dev,
		netopt_t	opt,
		const void *	value,
		size_t	value_len
	)

Fallback function for netdev ethernet devices' _set function.

Parameters

[in]	dev	network device descriptor
[in]	opt	option type
[in]	value	value to set
[in]	value_len	the length of value

Returns

number of bytes used from value

<0 on error
