Make sure rx descriptor ring align on 16 bytes. I guess the alignment requirement could be multiple of 4 bytes but I think using descriptor size would make intention clearer. Previously the size of rx descriptor was not power of 2 so it caused panic in bus_dmamem_alloc(9). Reported by: Jeff Blank (jb000003 <> mr-happy dot com) Approved by: re (kib)
