[c-nsp] ASR9K IOS-XR 4.3.2 or 5.1.0

[Claes Jansson]

Hi, we're currently running 4.2.3 and need to upgrade to get support for 
A9K-MPA-8X10GE.

Both releases are quite fresh, does anyone have any input on pros and 
cons on witch release to try out..?
    I've read that downgrade from 4.3.0 to 4.2.x could be a problem...

We're running L2 and L3 vpn to ME3600X devices and about 400 IPTV 
streams/channels in 4 vrf's (pim/gmp peering).

Tnx!
