[cisco-voip] VMware 5.5

[Charles Goldsmith]

This discussion comes up about every 6 months on this list, LRO is no
longer affected and was only a 4.1 issue on esxi.

http://docwiki.cisco.com/wiki/Unified_Communications_VMware_Requirements#Supported_Versions.2C_Patches_and_Updates_of_VMware_vSphere_ESXi


The latter being definitive for me, they keep that doc updated pretty well
and note, it states 4.1, not any other version of esxi.

Martin has another issue.  :)
