[net-next v2 2/6] fm10k: reduce duplicate fm10k_stat macro code

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

From: Jacob Keller <jacob.e.keller@intel.com>

Share some of the code for setting up fm10k_stat macros by implementing
an FM10K_STAT_FIELDS macro which we can use when setting up the type
specific macros.
