[9fans] Ethernet, PCI and OCP

[tlaronde]

I'm currently trying to augment the ether8169 driver to support
Realtek 8125 and 8126.

It's a mess and a maze (I'm working with the Realtek published driver
for FreeBSD, due to the license). [But I will probably swith to the
NetBSD/OpenBSD driver, that has the same king of license, but is far
more understandable. The Linux one is daunting as well...]

If I can untangle what is added for support of different archs,
alignments, endianness, threads, handling of buffer, DMA and so on, I'm
(more than) a bit puzzled with what concerns OCP.

From a very cursory look, OCP seems to be both a hardware feature
(smaller cards for servers) and additional software capabilities
(dealing with hardware acceleration).

There is a bunch of code dealing with OCP concurrently with "normal"
config done as usual via mapped registers---and I'm trying to get the
config right.

Has anybody some clue about the question of ignoring absolutely anything
having to deal with OCP (things will work even if not with optional
hardware acceleration)?
