Subject: nfp: loosen relation between rings and IRQs vectors
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0668b60ba60228cb0fa21bc69baa6269edf7b6d3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

nfp: loosen relation between rings and IRQs vectors

Upcoming XDP support will break the assumption that one can iterate
over IRQ vectors to get to all the rings easily.  Use nn->.x_ring
arrays directly.
