Subject: net: ngbevf: init interrupts and request irqs
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=0f71e3a6e59daa000bcebdbeab6bafda3747f3f9;p=thirdparty%2Flinux.git

net: ngbevf: init interrupts and request irqs

Add specific parameters for irq alloc, then use
wx_init_interrupt_scheme to initialize interrupt
allocation in probe.
Add .ndo_start_xmit support and start all queues.
