Hi everybody,
I was looking at network chapter of LDD3. The .ndo_start_xmit member
of struct net_device_ops should return netdev_tx_t which are:
enum netdev_tx {
__NETDEV_TX_MIN = INT_MIN, /* make sure enum is signed */
NETDEV_TX_OK = 0x00, /* driver took care of packet */
NETDEV_TX_BUSY = 0x10, /* driver tx path was busy*/
NETDEV_TX_LOCKED = 0x20, /* driver tx lock was already taken */
};
I'm deling with some awkward hardware where the MTU is only 32 bytes
and was wondering. What should that function return in case of "too
large packet"?!?!?
Best regards,
