From ea0f0d8bc6d13c2580d668ecf95297d5105a57fc Mon Sep 17 00:00:00 2001 From: Vasanthy Kolluri Date: Tue, 8 Mar 2011 15:35:30 +0000 Subject: enic: Support newer version of firmware devcmd CMD_MCPU_FW_INFO This patch provides support to the newer version of firmware devcmd CMD_MCPU_FW_INFO that returns additional information (ASIC type and revision) about the underlying hardware. This knowledge is required by the driver to implement any hardware specific features. Signed-off-by: Vasanthy Kolluri Signed-off-by: Roopa Prabhu Signed-off-by: David Wang Signed-off-by: David S.
