Subject: [net-next 06/15] igb: Refactor of init_nvm_params
From: Carolyn Wyborny <carolyn.wyborny@...el.com>
This patch refactors the init_nvm_params functions for 82575 and adds a new
function for the i210/i211 devices in order to configure separately the NVM
functionality for the i210/i211 family.
