error 12 means ENOMEM. bus_dmamap_load_mbuf_sg(9) failed due to
insuffcient resources. I guess there is no way to overcome this
situation in driver. The only remaining way I can think of would be
reclaiming of transmitted frames but how well it works would depends
on circumstances. Personally I don't see a reason to print these
ENOMEM errors for production box without late limiting.
