netdev: Add ability to permanently set device flags.

netdev: Add more functions for manipulating device flags.
...
These are convenient for use in secchan and elsewhere.

netdev: New function netdev_drain().

netdev: Add argument to netdev_open() to specify Ethernet type to capture.
...
This is needed by the controller, which wants to listen only for
OpenFlow discovery BPDUs on its network devices.
Also, update all existing callers.

netdev: Do not modify the caller's buffer in netdev_send().
...
This makes it possible to use a buffer whose contents are stack-allocated.

New function netdev_arp_lookup().
...
The secchan needs to handle ARP requests from the controller itself, so
it has to translate the controller's IP address into a MAC address to
allow it to match those packets on dl_src. (OpenFlow doesn't allow us
to look into ARP packets and match on the encapsulated IP addresses, so
this is the best we can do.)

New functions for getting and setting network device flags.
...
This allows us to open network devices without bringing them up
and setting them for promiscuous mode, which will be useful in the
secchan for in-band communication.

Expose device IP addresses through netdev.
...
This will be useful for the secure channel later.
2008-05-28 10:46:54 -07:00

Move netdev from switch to lib.
...
This is in preparation for the secure channel wanting to access
network devices.
