428 * The RealTek doesn't use a fragment-based descriptor mechanism.
429 * Instead, there are only four register sets, each or which represents
430 * one 'descriptor.' Basically, each TX descriptor is just a contiguous
431 * packet buffer (32-bit aligned!) and we place the buffer addresses in
432 * the registers so the chip knows where they are.
434 * We can sort of kludge together the same kind of buffer management
435 * used in previous drivers, but we have to do buffer copies almost all
436 * the time, so it doesn't really buy us much.
438 * For reception, there's just one large buffer where the chip stores
439 * all received packets.
