[cisco-voip] VMware 5.5

[Charles Goldsmith]

That page specifically says you don't have to disable LRO if you are above
4.1 esxi and 8.6 CUCM.

Martin, which version of 5.5 are you on?  GA, update 1 or 2?  I recently
ran into an issue with a customer on 5.5 u1 and too new of raid drivers on
the card and had to downgrade the drivers.  Wasn't causing 100% cpu, but
very slow drive access times.

So checked your vmware version and compatibility on the hardware you are
running.
