Subject: [RFC][PATCH net-next] cxgb4: Do not set net_device::dev_id to VI
 index

net_device::dev_id should not be used merely to indicate a VI index,
as it affects the way the local part of IPv6 addresses is normally
generated.

This field was intended for use where multiple devices may share a
single assigned MAC address and need to have different IPv6 addresses.
T4 VIs each have their own MAC address.

Dimitris, I don't know whether my last statement ('VIs each have their
own MAC address') is actually correct.  If not then the driver is quite
right to set dev_id.

Ben.
