e1000e: initialize manageability (IPMI) pass-through in 82574/82583
82574/82583 uses different registers/bits to setup manageability filters than all other parts supported by e1000e; set them accordingly for IPMI pass-through. Rename the function to better reflect what it does. Signed-off-by: Bruce Allan <bruce.w.allan@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.
