[c-nsp] PIM BiDir on Nexus

[James Slepicka (c-nsp)]

Bidir PIM is not supported on F2 modules.  Nor is it supported with vPC.

Colin-
Thx for the feedback.  I'm looking at the the F2 cards on nx-7k; are you doing this on the older M-series cards?  Also are you also doing specifically BiDir PIM?  Standard PIM (SM specifically for use-case in question here) seems to work but without some minor hiccups on the newer
F2 cards.  Thx again.

:-)
