From 38353364015c64cde0ba30564069eb88874aa8ec Mon Sep 17 00:00:00 2001 From: Yishai Hadas Date: Sun, 29 Jan 2017 18:56:14 +0200 Subject: [PATCH] net/mlx4_core: Device revision support The device revision field returned by the NodeInfo MAD is incorrect on ConnectX3 devices. This patch is driver side handling to complete a FW fix added at 2.11.1172. INIT_HCA - bit at offset 0x0C.12 is set to 1 so that FW will report correct device revision. Older FW versions won't be affected from turning on that bit, no capability bit is needed. Signed-off-by: Yishai Hadas Signed-off-by: Tariq Toukan Signed-off-by: David S.
