Hi, For SocketCAN I would like to implement the POLLOUT functionality. However this means I've to query the driver check if the internal TX buffer is full. My first thought would be extending struct net_driver_s with the following callback int (*d_txfull)(FAR struct net_driver_s *dev); Would this make sense or is there a better way to query the driver from network stack?
Kind regards Peter van der Perk
