Hi David,
I have a patch to enable IPv6 with the WLP code that comes with the UWB
drivers. It basically checks for multicast and broadcast addresses
instead of broadcast only when transmitting data.
However I am still puzzled about the comment in drivers/uwb/wlp/txrx.c:
"... but we don't support multicast yet (until devices start to support
MAB IEs) ...".
It seems like they left out multicast intentionally. I do not know what
to make out of it. Did they just think of IPv4 multicast features or
also IPv6? Anyhow we do not had or see any problems by applying the
patch.
Frank
Here is the patch:
-----------------------------------------------------------
Enables WLP to be used with IPv6. Now Ethernet multicast addresses are
supported that are frequently used in IPv6 traffic.
