mlx4_en: Added self diagnostics test implementation
The selftest includes 5 features: 1. Interrupt test: Executing commands and receiving command completion on all our interrupt vectors. 2. Link test: Verifying we are connected to valid link partner. 3. Speed test: Check that we negotiated link speed correctly. 4. Registers test: Activate HW health check command. 5. Loopback test: Send a packet on loopback interface and catch it on RX side. Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>
