This patch fixes following issues:
---> PHY auto detection & PHY access issues.
---> The existing lwip seems to misbehave when it undergoes a stress or
performance test with UDP packets.
---> Temac crashes and deadlocks if there is a high traffic load or transmitted
packets are not successfully delivered to the other side.
