Function Documentation

eth_adin2111_broadcast_filter()

int eth_adin2111_broadcast_filter	(	const struct device *	dev,
		bool	enable )

Enable/disable the forwarding (to host) of broadcast frames.

Frames who's DA doesn't match are dropped.

Note

The caller is responsible for device lock. Shall not be called from ISR.

Parameters

[in]	dev	ADIN2111 device.
	enable	Set to 0 to disable and to nonzero to enable.

Returns

0 on success, negative errno value on failure.

eth_adin2111_get_iface()

struct net_if * eth_adin2111_get_iface	(	const struct device *	dev,
		const uint16_t	port_idx )

Get the port-related net_if reference.

Parameters

[in]	dev	ADIN2111 device.
	port_idx	Port index.

Return values

a	struct net_if pointer, or NULL on error.

eth_adin2111_lock()

int eth_adin2111_lock	(	const struct device *	dev,
		k_timeout_t	timeout )

Locks device access.

Parameters

[in]	dev	ADIN2111 device.
	timeout	Waiting period to lock the device, or one of the special values K_NO_WAIT and K_FOREVER.

Return values

0	Device locked.
-EBUSY	Returned without waiting.
-EAGAIN	Waiting period timed out.

eth_adin2111_mac_reset()

int eth_adin2111_mac_reset

(

const struct device *

dev

)

Reset the MAC device.

Note that PHY 1 must be out of software power-down for the MAC subsystem reset to take effect.

Note

The caller is responsible for device lock. Shall not be called from ISR.

Parameters

[in]

dev

ADIN2111 device.

Returns

0 on success, negative errno value on failure.

eth_adin2111_sw_reset()

int eth_adin2111_sw_reset	(	const struct device *	dev,
		uint16_t	delay )

Reset both the MAC and PHY.

Parameters

[in]	dev	ADIN2111 device.
	delay	Delay in milliseconds.

Note

The caller is responsible for device lock. Shall not be called from ISR.

Returns

0 on success, negative errno value on failure.

eth_adin2111_unlock()

int eth_adin2111_unlock

(

const struct device *

dev

)

Unlocks device access.

Parameters

[in]

dev

ADIN2111 device.

Return values

0	Device unlocked.
-EPERM	The current thread does not own the device lock.
-EINVAL	The device is not locked.
