Subject: [PATCH 6/8] bootp: Add processing DHCPACK packet from HTTP Boot
|
|
|
|
The vendor class identifier with the string "HTTPClient" is used to denote the
|
|
packet as responding to HTTP boot request. In DHCP4 config, the filename for
|
|
HTTP boot is the URL of the boot file while for PXE boot it is the path to the
|
|
boot file. As a consequence, the next-server becomes obseleted because the HTTP
|
|
URL already contains the server address for the boot file. For DHCP6 config,
|
|
there's no difference definition in existing config as dhcp6.bootfile-url can
|
|
be used to specify URL for both HTTP and PXE boot file.
|
|
|
|
This patch adds processing for "HTTPClient" vendor class identifier in DHCPACK
|
|
packet by treating it as HTTP format, not as the PXE format.
