On x86 architecture, Ziatech have CompactNet, which uses the 21554 non-transparent bridge. This should be portable to PowerPC, though some work may be required: http://www.compactnet.com/ I've done some similar work on a PowerPC, but on PCI cards and using a very different core logic design which avoided the need for a non-transparent bridge: http://www.agelectronics.co.uk/tpe3.html The kernel for this board passes ethernet frames over the PCI backplane between boards. The novelty over traditional shared memory networking is the use of I2O units. - Adrian Cox, AG Electronics ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
