From e7b0e5f72e134779cfe22cd07b09a42c22d2bfe1 Mon Sep 17 00:00:00 2001 From: Mark Goddard Date: Wed, 26 Sep 2018 17:59:07 +0000 Subject: Add support for Infiniband network interfaces (IPoIB). OpenStack ironic references Infiniband interfaces via a 6 byte 'MAC address' formed from bytes 13-15 and 18-20 of interface's hardware address. This address is used as the ethernet_mac_address of Infiniband links in network_data.json in configdrives generated by OpenStack nova. We can use this address to map links in network_data.json to their corresponding interface names. When generating interface configuration files, we need to use the interface's full hardware address as the HWADDR, rather than the 6 byte MAC address provided by network_data.json. This change allows IB interfaces to be referenced in this dual mode - by MAC address and hardware address, depending on the context. Support TYPE=InfiniBand for sysconfig configuration of IB interfaces. --- cloudinit/net/network_state.py | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'cloudinit/net/network_state.py') diff --git a/cloudinit/net/network_state.py b/cloudinit/net/network_state.py index 72c803eb..f76e508a 100644 --- a/cloudinit/net/network_state.py +++ b/cloudinit/net/network_state.py @@ -483,6 +483,10 @@ class NetworkStateInterpreter(object): interfaces.update({iface['name']: iface}) + @ensure_command_keys(['name']) + def handle_infiniband(self, command): + self.handle_physical(command) + @ensure_command_keys(['address']) def handle_nameserver(self, command): dns = self._network_state.get('dns') -- cgit v1.2.3
