takes care of all the 10/100 and gigE PCI drivers that I've done. Next will be the wireless drivers, then the USB ones. I may pick up some stragglers along the way. I'm sort of playing this by ear: if anyone spots any places where I've screwed up horribly, please let me know.

* Compute offset of port-specific register. Since there are two
|
|
* ports, there are two of some GEnesis modules (e.g. two sets of
|
|
* DMA queues, two sets of FIFO control registers, etc...). Normally,
|
|
* the block for port 0 is at offset 0x0 and the block for port 1 is
|
|
* at offset 0x80 (i.e. the next page over). However for the transmit
|
|
* BMUs and RAMbuffers, there are two blocks for each port: one for
|
|
* the sync transmit queue and one for the async queue (which we don't
|
|
* use). However instead of ordering them like this:
|
|
* TX sync 1 / TX sync 2 / TX async 1 / TX async 2
|
|
* SysKonnect has instead ordered them like this:
|
|
* TX sync 1 / TX async 1 / TX sync 2 / TX async 2
|
|
* This means that when referencing the TX BMU and RAMbuffer registers,
|
|
* we have to double the block offset (0x80 * 2) in order to reach the
|
|
* second queue. This prevents us from using the same formula
|
|
* (sk_port * 0x80) to compute the offsets for all of the port-specific
|
|
* blocks: we need an extra offset for the BMU and RAMbuffer registers.
|
|
* The simplest thing is to provide an extra argument to these macros:
|
|
* the 'skip' parameter. The 'skip' value is the number of extra pages
|
|
* for skip when computing the port0/port1 offsets. For most registers,
|
|
* the skip value is 0; for the BMU and RAMbuffer registers, it's 1.
