From 5ae2a7a836be660ff1621cce1c46930f19200589 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 18 Jun 2007 08:15:02 -0700 Subject: IB/mlx4: Handle FW command interface rev 3 Upcoming firmware introduces command interface revision 3, which changes the way port capabilities are queried and set. Update the driver to handle both the new and old command interfaces by adding a new MLX4_FLAG_OLD_PORT_CMDS that it is set after querying the firmware interface revision and then using the correct interface based on the setting of the flag.
