> Mhhhh, since these are things that do not change at runtime: is there maybe a way how to figure this out at compile-time (ideally with keeping multi-device support and keeping code-duplication low ;-))?

Just tossing some ideas, but how about a link-layer specific "MAC driver" struct (names are just examples take from the flags, please don't consider them to be serious)?

```C
typedef struct {
    int tx_checksum(netdev_ieee802154_t *dev, ...);
    int csma(netdev_ieee802154_t *dev, ...);
    /* ... */
} netdev_ieee802154_mac_ops_t;
```

A driver then can set the once it supports in hardware to NOP, and otherwise use some common MAC implementation.
