  Fail to chainload iPXE (undionly.kpxe)

Status in ironic package in Ubuntu:

Bug description:
  I was working on a DELL R630 and it was failing to chainload the
  undionly.kpxe configuration in the way we set the DHCP configuration
  in Neutron.

  By manually tweaking stuff I could get it to work. Here's what I had
  to change:

  * In Ironic:

  diff --git a/ironic/common/pxe_utils.py b/ironic/common/pxe_utils.py
  index b24b716..40a4469 100644
  --- a/ironic/common/pxe_utils.py
  +++ b/ironic/common/pxe_utils.py
  @@ -267,7 +267,7 @@ def dhcp_options_for_instance(task):
                                 'opt_value': CONF.pxe.pxe_bootfile_name})
           # If the request comes from iPXE, direct it to boot from the
           # iPXE script
  -        dhcp_opts.append({'opt_name': 'bootfile-name',
  +        dhcp_opts.append({'opt_name': 'tag:ipxe,bootfile-name',
                             'opt_value': ipxe_script_url})
       else:
           if deploy_utils.get_boot_mode_for_deploy(task.node) == 'uefi':

  
  * In the custom dnsmasq we create for creating the "ipxe" tag in Neutron:

  $ cat /etc/dnsmasq-ironic.conf 
  dhcp-userclass=set:ipxe,iPXE

  (Instead of dhcp-match:set:ipxe,175) Tho dhcp-match should work, I
  just don't know why it didn't for that machine. Perhaps we should
  document both
