DHCP renewal send as IP unicast but using Broadcast on Layer II

Hi,

When debugging some issues with non working DHCP renewals I discovered that some version (more details later) of dhcpcd are correctly sending the renewal DHCP requests to the IP Address of the DHCP server (unicast).

But these renewal packets contain the Layer II broadcast address FF:FF:FF:FF:FF:FF while it is expected that they use the MAC address of the gateway instead.

Can you confirm that that sending a unicast DHCP renewal to the broadcast address would be a bug?

Best regards,
