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