Subject: [net-next 09/10] igb: Refractoring function pointers in igb_get_invariants function
From: "Akeem G. Abodunrin" <akeem.g.abodunrin@...el.com>
This patch simplifies igb_get_invariants function by moving all implemented
function pointers in this function to individual separate functions,
based on their functionalities, this would make debugging much easier.
