#1442008 — [PATCH v2 11/15] net: thunderx: Use netdev's name for naming VF's interrupts

From: Sunil Goutham <sgoutham@cavium.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.
