From e7c1c2c46201e46f8ce817196507d2ffd3dafd8e Mon Sep 17 00:00:00 2001 From: Yevgeny Petrilin Date: Tue, 24 Aug 2010 03:46:18 +0000 Subject: 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.
