Update vnet hardware flags if link state changes
Explains a variety of hard-to-diagnose problems with certain Atom and
Denverton NIC types.
I finally tripped over a highly-repeatable failure: home gateway
use-case bitten by refusal to negotiate a DHCP lease for the trunk
port.
The dhcp client won't send pkts unless VNET_HW_INTERFACE_FLAG_LINK_UP
is set on the tx hw interface:
/* Interface(s) down? */
if ((hw->flags & VNET_HW_INTERFACE_FLAG_LINK_UP) == 0)
return;
