I'm not sure it can be implemented in software, due to the non-realtime nature of the Linux kernel. The mrf24j40 datasheet hints at it almost being a requirement to be done in hardware because of the timing requirements of the 802.15.4 standard. > One > example would be when we have a monitor device configured.

I sent an email to netdev (probably CC'd here) about this a few months ago. There's support for it (multiple wpans on a single phy) in the code, but I don't understand how it would be physically possible to have multiple wpan devices on a single phy. A hardware phy just isn't set up that way. You're talking about short addresses (which could be handled in software with promiscuous mode turned on in hardware), but the current implementation even allows for separate channels, which seems impossible. > I fear there are already some problems with the way the current mainline > code handles the hardware address filtering in mib.c.
