Didn't we change it to not be user defined?

I think it should rather be "if the attribute is not specified, no TTL
is used", with 0 being an invalid value.

That probably needs to say what kind if "binary values"?

Ditto.

"true" and "false" aren't really states for a flag, it can be
"specified" or "not specified", or maybe "present" and "not present".

Likewise.
However, why do you even need two attributes? It doesn't seem relevant
to specify the NAN_SRF_BF attribute when NAN_SRF_TYPE_BF isn't set?

Likewise - what do you need the SRF_TYPE_BF flag for at all?

And this is obviously the opposite - so both SRF_MAC_ADDRS and
SRF_BR/BF_IDX can't be specified together. No need for the flag?

No need for those casts.
