* better keep with a flood of tiny Ethernet packets.
|

|
|
* The receive space MUST ALWAYS be a multiple of the page size.
|
|
* And the number of receive descriptors multiplied by the size
|
|
* of the receive buffers must equal the recevive space. This
|
|
* is so that we can manipulate the page tables so that even if a
|
|
* packet wraps around the end of the receive space, we can
|
|
* treat it as virtually contiguous.
|
|
*
|
|
* The above used to be true (the stupid restriction is still true)
|
|
* but we gone to directly DMA'ing into MBUFs (unless it's on an
|
|
* architecture which can't handle unaligned accesses) because with
|
|
* 100Mb/s cards the copying is just too much of a hit.
