+This hook loads the necessary modules for a network device.
+Detection will take place at runtime. To minimize the modules
+in the image, add the autodetect hook too.
+For pcmcia net devices please use pcmcia hook too.
+
+Kernel Parameters:
+
+BOOTIF=01-<bootif-mac>
+aoe_iflist=<iface>[,<iface>...]
+aoe_discover_timeout=<discover-timeout>
+root=/dev/etherd/e<shelf>.<slot>[p<part>
+
+If neither BOOTIF=... nor aoe_iflist=... are specified, all available
+network interfaces will be brought up and made available for AoE.
+Depending on network infrastructure, this may pose a security risk,
+but it is useful for testing.
+
+If only BOOTIF=... is specified, the associated network interface will
+be made available for AoE.
+
+When using PXELINUX as bootloader, the line 'IPAPPEND 2' can be added
+to its configuration file to have the BOOTIF parameter added to the
+kernel commandline automatically, based on information from DHCP.
+
+If aoe_iflist=... is specified, it will override any network interface
+determined by the BOOTIF=... parameter.
+
+<bootif-mac>        MAC address of the network interface used for
+                    booting.
+<iface>             Name of a network interface to bring up and make
+                    available for AoE device discovery.
+<discover-timeout>  Time (in seconds) to wait for discovery of the
+                    AoE root device. Defaults to 10 seconds.
+<shelf>             As specified in the AoE device configuration.
+<slot>              As specified in the AoE device configuration.
+<part>              Partition on an AoE device. Use this only if
+                    the device containins a partition table.
