>Environment:
PS/2 mod 50z with PowerBoard Upgrade
>Description:
Attached are files and diffs to add a driver for the Tiara LANCard and friends based on the Fujitsu mb86950 EtherStar chip. Code is included to ID and attach the Microchannel version of the SMC 3016. This code for the 3016 has not been tested.
There may be some minor pieces missing here and there that should be in a NetBSD ethernet driver. I put in only what was necessary to get the Tiara LANCard to work.
Limitations:
Multicast is not supported
The Tiara adf file (@6000.adf) lists IRQ6 as an interrupt choice. IRQ6 is incorrect. The hardware can interrupt on IRQ7 not IRQ6. Nobody ever changed the adf file.
(Please excuse style mistakes -- it's been a long time since I've done C ..)

/* XXX There are still rough edges......
* (1) There is no watchdog timer for the transmitter. It's doubtful that
* transmit from the chip could be restarted without a hardware reset though.
Fixed - not fully tested
* (2) The media interface callback goo is broke. No big deal since to change
* from aui to bnc on the old Tiara LANCard requires moving 8 board jumpers.
* Other cards (SMC ?) using the EtherStar chip may support media change via software.
Fixed - tested
* (3) The maximum outstanding transmit packets is set to 4. What is a good limit
* of outstanding transmit packets for the EtherStar? Is there a way to tell how
* many bytes are remaining to be transmitted? [no]
---
When the EtherStar was designed, CPU power was a fraction of what it is now. The
single EtherStar transmit buffer was fine. It was unlikely that the CPU could
outrun the EtherStar. However, things in 2004 are quite different. sc->txb_size
is used to keep the CPU from overrunning the EtherStar. At most allow one packet
transmitting and one going into the fifo.
---
No, that isn't right either :(
* (4) Multicast isn't supported. Feel free to add multicast code if you know how
* to make the EtherStar do multicast. Otherwise you'd have to use promiscuous mode
* and do multicast in software. OUCH!
* (5) There are no bus_space_barrier calls used. Are they needed? Maybe not.
* (6) Access to the fifo assumes word (16 bit) mode. Cards configured for byte
* wide fifo access will require driver code changes.
* Only the minimum code necessary to make the Tiara LANCard work has been tested.
* Other cards may require more work, especially byte mode fifo and if DMA is used.
