[dhcp] Accept ProxyDHCP replies of type DHCPOFFER
|
||
|
|
|
||
|
|
The PXE standard provides examples of ProxyDHCP responses being encoded both
|
||
|
|
as type DHCPOFFER and DHCPACK, but currently we only accept DHCPACKs. Since
|
||
|
|
there are PXE servers in existence that respond to ProxyDHCPREQUESTs with
|
||
|
|
DHCPOFFERs, modify gPXE's ProxyDHCP pruning logic to treat both types of
|
||
|
|
responses equally.
