Test connectivity when using multiple tcp/ip stacks

It is possible for ESXi host to use multiple TCP/IP stacks. In that case to validate connectivity between two ESXi hosts use:

1. Get list of network stacks using:

   esxcli network ip netstack list

2. Understand which vmkernel port is using which TCP/IP stack using:

   esxcli network ip interface  list | grep -i 'name\|stack'

3. ping with appropriate stack name to remote machine on corresponding network using:

   ping -s <stack-name> <remote-ip>

   For example

   ping -S "vmotion" 10.2.23.57
