Subject: [PATCH v2 13/21] net: thunderx: Use netdev's name for naming VF's interrupts

From: Sunil Goutham <sgoutham@...ium.com>

This patch changes the way VF's irqs are visible in /proc/interrupts.
Instead of VF id, logical interface's netdev name is used for IRQ
naming and also all secondary VF's interrupts in multiqset config
use primary VF's netdev name.
