[net-next PATCH 20/26] igb: change pba size determination from if to switch statement

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Alexander Duyck <alexander.h.duyck@intel.com>

As additional hardware is added to the igb driver it is easier to support
the expansion via switch statements instead of using nested ifs.  For
this reason I am changing this to a switch statement.
