[j-nsp] Inline jflow - No hash table changes

[Graham Brown]

Hi Scott,

Without taking a look at the implementation guides I can't answer this with
100% certainty, however look for PRs before deploying inline-jflow as it's
bitten a fair few people.

We're currently waiting for the next release of Junos to resolve a jflow
issue / issues.

Cheers,
Graham
