WPS Pixie Dust Attack (Offline WPS Attack)

[squash]

my router is not listed, so how do i know if it's vulnerable or not? Obviously reaver with -K option finds nothing, because it's not programmed into pixiedust.
it's a Broadcom
WPS Model Name: Broadcom
WPS Model Number: 123456
AP Serial Number: 1234

It shows the r-nonce, PKR, authkey, hash1, hash2 ..etc, but it finds nothing, obviously because router is never been tested, so how can i find out if my router is vulnerable to pixiedust attack?
does someone ever like update the list?
I also noticed lot of other routers that are not listed. Routers used in Sweden are not listed, some routers used in UK are not listed and most routers used in Finland are not listed either, is this some USA based thing or something?

I think its most USA router listed cuz most users in this forum lives there.
But i know pixie works on a lot of routers even in Sweden where i live.

I dont fully understand pixie dust yet. is there any type of "calculator" which can be used to test new routers against pixie dust?
