From f6bc11e42646e661e699a5593cbd1e9dba7191d0 Mon Sep 17 00:00:00 2001 From: Yishai Hadas Date: Sun, 25 Jan 2015 16:59:38 +0200 Subject: net/mlx4_core: Enhance the catas flow to support device reset This includes: - resetting the chip when a fatal error is detected (the current code does not do this). - exposing the ability to enter error state from outside the catas code by calling its functionality. (E.g. FW Command timeout, AER error). - managing a persistent device state. This is needed to sync between reset flow cases.
