The issue is that when using dhclient from the client on Ubuntu (and only on Ubuntu) with MOFED or inbox driver, we see that that DHCP server offers in unicast instead of broadcast. It seems there is no way to correct this from the client side using dhclient configuration file. this issue exist even when we use always-broadcast statement in configuration file. in other vendors we see that discover request type is broadcast. attached pcap files from working (other vendor) and not working (Ubuntu) clients.
