The differences between these messages are different dhcp xids (0x0134cb48 versus 0x0134cb4b) and, if I'm counting correctly, different dhcp yiaddrs. I see no other differences other than the first frame being cut off after 128 bytes. That is undoubtedly because you did not tell the switch to send more than 128 bytes, which is the default. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
