Function Documentation
| void csp_iflist_add | ( | csp_iface_t * | ifc | ) |
Register your interface in the router core using this function.
This must be done in the interface init() function.

| csp_iface_t * | interface, | ||

| ) |
Inputs a new packet into the system This function is called from interface drivers ISR to route and accept packets.
But it can also be called from a task, provided that the pxTaskWoken parameter is NULL!
EXTREMELY IMPORTANT: pxTaskWoken arg must ALWAYS be NULL if called from task, and ALWAYS be NON NULL if called from ISR! If this condition is met, this call is completely thread-safe
This function is fire and forget, it returns void, meaning that a packet will always be either accepted or dropped so the memory will always be freed.
- Parameters
-
packet A pointer to the incoming packet interface A pointer to the incoming interface TX function. pxTaskWoken This must be a pointer a valid variable if called from ISR or NULL otherwise!
| uint8_t csp_route_get_mac | ( | uint8_t | node | ) |
Get MAC layer address of next hop.
- Parameters
-
node Next hop node
- Returns
- MAC layer address
