NetXen: Make driver use multiple PCI functions. This patch will make NetXen driver work with multiple PCI functions. This will make the usage of memory resources as well as interrupts more independent among different functions which results in better throughput. This change has been done after the multiport support is added in firmware. Signed-off by: Mithlesh Thukral <mithlesh@netxen.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
