|

* the data to non-longword aligned. Since IP requires the
|
||
* data to be longword aligned, we need to copy it after it has
|
||
* been DMA'ed in our memory.
|
||
*
|
||
* Since we have to copy it anyways, we might as well as allocate
|

* dedicated receive space for the input. This allows to use a
|
||
* small receive buffer size and more ring entries to be able to
|
||
* 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 because with 100Mb
|
||
