I'm now able to get the driver running for all 8 interfaces, according to dmesg. I can bring up the first few interfaces and ping devices attaches to them successfully after setting up routing, but eventually dmesg starts telling me the following:
[76631.886445] e1000: rteth5: e1000_setup_rx_resources: Unable to allocate memory for the receive descriptor ring [76631.886553] e1000: rteth5: e1000_setup_all_rx_resources: Allocation for Rx Queue 0 failed [76619.534006] e1000: rteth6: e1000_setup_rx_resources: Unable to allocate memory for the receive descriptor ring [76619.534111] e1000: rteth6: e1000_setup_all_rx_resources: Allocation for Rx Queue 0 failed I'm afraid I don't understand xenomai/rtnet/kernel stuff well enough to be sure what memory I've run out of or how to make more of it available.
