[j-nsp] Unable to load-balance VPLS traffic

[Huan Pham]

Thanks Per for the info. It is very helpfull.

By default, on MX5, enhanced hash key is already enabled for VPLS payload.
However, we have to delete the standard hash-key configuration, otherwise,
somehow it causes unexpected behaviour, and disable load-balancing for
certain criteria.

Below command is also helpful in verifying hash-key configuration.
