+# Config file for mlx4 hardware port settings
+# This file is read when the mlx4_core module is loaded and used to
+# set the port types for any hardware found.  If a card is not listed
+# in this file, then its port types are left alone.
+#
+# Format:
+# <pci_device_of_card> <port1_type> [port2_type]
+#
+# @port1 and @port2:
+#   One of auto, ib, or eth.  No checking is performed to make sure that
+#   combinations are valid.  Invalid inputs will result in the driver
+#   not setting the port to the type requested.  port1 is required at
+#   all times, port2 is required for dual port cards.
+#
+# Example:
+# 0000:0b:00.0 eth eth
+#
+# You can find the right pci device to use for any given card by loading
+# the mlx4_core module, then going to /sys/bus/pci/drivers/mlx4_core and
+# seeing what possible PCI devices are listed there.  The possible values
+# for ports are: ib, eth, and auto.  However, not all cards support all
+# types, so if you get messages from the kernel that your selected port
+# type isn't supported, there's nothing this script can do about it.  Also,
+# some cards don't support using different types on the two ports (aka,
+# both ports must be either eth or ib).  Again, we can't set what the kernel
+# or hardware won't support.
