Miller Resize and regroup structure members to eliminate memory holes and to pack the structure into 2 cache lines (from 3). tx_ring_size was resized from 4 to 2 bytes and few members were re-grouped in order to eliminate byte holes and achieve compactness. Where possible, few members were grouped according to their usage and access order (i.e. start_xmit vs. clean_tx_ring members), less important members were pushed at the end.

Also, it would be wasteful to have memory holes inside struct gfar_priv_grp, in this context, and the current patch resolves those memory holes, by compacting this structure to exactly 96 bytes. I don't find this change over complicated, but I'm open to suggestions on where to move those message texts, outside of gfar_priv_grp (or other runtime critical structure).
