Description
In the DHCP Leases table, we see the assigned manufacturer displayed beside each MAC address.
This would be extremely useful information to have on the ARP Table display also.
Here's a diff that implements it. I haven't been a PHP programmer for 20 years, I don't claim this is production-quality.
