The NICs are detected, and appear to be able to receive traff= ic (IPv6 SLAAC works, tcpdump shows broadcast/multicast traffic), but the NICs= are unable to transmit. dhclient complains send_packet: No buffer space availa= ble. After configuring a static address with ifconfig, attempts to send packets= via ping do not show up in a tcpdump.
