Hi all:
I creat a hepervisor, and guest is andriod OS. When I unpulged network cable, the virtual network interface of guest is 
still carrier. I want to know guest how to get the physical status of network interface. Or, host (QNX OS) how get the 
physical status of network interface through interrupt  or blocking instead of polling, I think that is also feasible 
for the host to notify the guest.

Thanks in advance!
