Function Documentation

◆ netdev_add_layer()

static netdev_t * netdev_add_layer ( netdev_t top,
netdev_t dev 
)
inlinestatic

Add a netdev layer to the netdev layer stack.

Parameters
[in]topLast netdev device added to the stack.
[in]devNew layer to push to the top of the stack.
Returns
The new top netdev layer of the netdev stack.

◆ netdev_event_cb_pass()

void netdev_event_cb_pass ( netdev_t dev,
netdev_event_t  event 
)

Passthrough event callback function.

Parameters
[in]devnetwork device descriptor
[in]eventtype of the event

◆ netdev_get_pass()

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

Passthrough get function.

See also netdev_driver for the extended description of this functions behaviour

Parameters
[in]devnetwork device descriptor
Returns
