+Subject: 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.
