perfdhcp -4 can't request options via option 55 Parameter Request List
Trying to request options from the server.
perfdhcp -6 -o 6,1234 works.
perfdhcp -4 -o 55,1234 does not.
ERROR: running perfdhcp: Option 55 already present in this message.
The culprit seems to be an empty option 55 automatically added to all packets.
// Set options: DHCP_MESSAGE_TYPE and DHCP_PARAMETER_REQUEST_LIST [...] pkt4->addOption(Option::factory(Option::V4, DHO_DHCP_PARAMETER_REQUEST_LIST));
Question is why is this done?
Does not replicate on v6 because options are not required to be unique on v6, but empty option 6 is added there as well.
Fix is supposedly as easy as removing the
addOption line. To be investigated.
