Marian Buschsieweke 53fcb97b2f drivers/net: Add netdev_driver_t::confirm_send ... Changed the API of `netdev_driver_t`: - The `send()` function should no longer return the number of bytes and should not block - The upper layer now must call the new `confirm_send()` function after calling `send()`; either busy waiting until something different to `-EBUSY` is returned, or after `NETDEV_EVENT_TX_COMPLETE` was signaled During transition to the new API, the upper layer must remain backward compatible and must assume the legacy API if `netdev_driver_t::confirm_send()` is `NULL`.		2021-01-05 15:34:11 +01:00
