When first initialized, cur_tx points to the 1st entry in the queue, and dirty_tx points to the last. At this point, fec_enet_get_free_txdesc_num will return tx_ring_size -2. If tx_ring_size -2 entries are now queued, then fec_enet_get_free_txdesc_num should return 0, but it returns tx_ring_size instead. Signed-off-by:
