Note:

In case of single descriptor, the ENET_IT_TX_DONE interrupt is the same as

ENET_TX_CURRENT_DONE. But the difference is noticed when a linked list of descriptors

is programmed:

- Enabling ENET_IT_TX_CURR_DONE will generate interrupt after the end of each

transmission.

- Enabling ENET_IT_TX_DONE will generate interrupt after the whole list chain

transmission.
