Option 122 was defined by Cable Labs. Here's something I wrote up before:

That syntax is from version 2.0.
In v3.0 and later there are user defined option names, so you need
to define your option name and the parameters it takes. See man
dhcp-options and look for the section titled "DEFINING NEW OPTIONS". In
this case you want something like:
# define the option, usually near the top of the file
option some-name-i-like code 122 = string;
# or
option option-122 code 122 = string;
# now fill in the value
option some-name-i-like = 01:04:ff:ff:ff:ff;
# or
option option-122 = 01:04:ff:ff:ff:ff;
