Subject: [PATCH] udhcpc: remove code which requires server ID to be on local
|
||||
network
|
||||
|
||||
This reverts "udhcpc: paranoia when using kernel UDP mode
|
||||
for sending renew: server ID may be bogus".
|
||||
|
||||
Users complain that they do have servers behind routers
|
||||
(with DHCP relays).
