I'm using Realtek card and starting from this revision Rx buffers cannot be allocated for my device. Please check out the message below: ----------------------------------------------------------------------------------- root@:~ # dhclient re0 re0: no memory for RX buffers re0: no memory for RX buffers DHCPREQUEST on re0 to 255.255.255.255 port 67 Aug 5 20:18:52 dhclient[898]: send_packet: Network is down ----------------------------------------------------------------------------------- Best regards Zbyszek Bodek
