[c-nsp] BFD on 12.2.33 SRA and SRB

[Rodney Dunn]

I'd strongly encourage anyone to go for SRB3 and later. We had a huge
bug fix push on the SRB throttle after SRB2 and it's been extremely
stable and that is where we are enouraging customers to go.

There were a lot of changes to BFD in the SRB timeframe for a lot of bugs.
