[Linuxptp-devel] [PATCH v4 01/11] Accept the full range for domainNumber.

[Richard C. <ric...@gm...>]

IEEE Std C37.238 invented its own rules with respect to the range of
values allowed for the domainNumber attribute.  The profile

    "complies with IEEE Std 1588-2008 with the exception of the use of
    the reserved domain 254. The value 254 is an exception granted to
    this profile."

In addition, Table 2 of IEEE Std 1588-2019 presents an incoherent
Swiss cheese of allowed ranges, depending sdoId and network transport.

Avoid the standardized madness by allowing the user to simply choose
any domainNumber they want.
