rS301270: Introduce a per-VNET flag to enable/disable netisr prcessing on that VNET.

Summary

Introduce a per-VNET flag to enable/disable netisr prcessing on that VNET.
Add accessor functions to toggle the state per VNET.
The base system (vnet0) will always enable itself with the normal
registration. We will share the registered protocol handlers in all
VNETs minimising duplication and management.
Update netisr consumers to (de)register on a per-VNET start/teardown using
VNET_SYS(UN)INIT functionality.
Upon disabling netisr processing for a VNET drain the netisr queue.

The change should be transparent for non-VIMAGE kernels.

Can you please update netisr manpage?

This revision now requires changes to proceed.Jun 2 2016, 6:21 PM

Updating netisr man page as requested.

Update epair(4) to nly hide the netisr call under VIMAGE on SYSUNINT
as we might unload the module using it in non-VIMAGE cases as well
(theoretically).
