Convert the mx driver to miibus. In order to make this work, I created a pseudo-PHY driver to deal with Macronix chips that use the built-in NWAY support and symbol mode port. This is actually all of them, with the exception of the original MX98713 which presents its NWAY support via the MII serial interface. The mxphy driver actually manipulates the controller registers directly rather than using the miibus_readreg()/miibus_writereg() bus interface since there are no MII registers to read. The mx driver itself pretends that the NWAY interface is a PHY locayed at MII address 31 for the sole purpose of allowing the mxphy_probe() routine to know when it needs to attach to a host controller.

Add the if_dc driver and remove all of the al, ax, dm, pn and mx drivers which it replaces. The new driver supports all of the chips supported by the ones it replaces, as well as many DEC/Intel 21143 10/100 cards. This also completes my quest to convert things to miibus and add Alpha support.

* Pseudo-driver for internal NWAY support on DEC 21143 and workalike
* controllers. Technically we're abusing the miibus code to handle
* media selection and NWAY support here since there is no MII
* interface. However the logical operations are roughly the same,
* and the alternative is to create a fake MII interface in the driver,
* which is harder to do.

Fix some problems reported by Mike Pritchard: - Add a flag DC_TX_INTR_ALWAYS which causes the transmit code to request a TX done interrupt for every packet. The PNIC seems to need this to insure that the sent TX buffers get reaped in a timely fashion. - Try to unreset the SIA as soon as possible after resetting the whole chip. - Change dcphy to support either 10/100 or 10Mbps only NICs. The built-in 21143 ethernet in Compaq Presario machines is 10Mbps only and it doesn't work right if we try to advertise 100Mbps modes during autoneg. When restricted to only 10mbps modes, it works fine. Note that for now, I detect this condition by checking the PCI subsystem ID on this NIC (which has a Compaq vendor/device ID). Yes, I know that's what the SROM is supposed to be for. I'm deliberately ignoring the SROM wherever possible. Sue me. The latter two fixes allow if_dc to work correctly with the built-in ethernet on certain Compaq Presario boxes. There are liable to be quite a few people using these as their home systems who might want to try FreeBSD; may as well be nice to them. Now if anybody out there has an Alpha miata with 10Mbps ethernet and can show me the output from pciconf -l on their system, I'd be grateful.

The PNIC seems to need this to insure that the sent TX buffers get reaped in a timely fashion. - Try to unreset the SIA as soon as possible after resetting the whole chip. - Change dcphy to support either 10/100 or 10Mbps only NICs. The built-in 21143 ethernet in Compaq Presario machines is 10Mbps only and it doesn't work right if we try to advertise 100Mbps modes during autoneg. When restricted to only 10mbps modes, it works fine. Note that for now, I detect this condition by checking the PCI subsystem ID on this NIC (which has a Compaq vendor/device ID). Yes, I know that's what the SROM is supposed to be for. I'm deliberately ignoring the SROM wherever possible. Sue me. The latter two fixes allow if_dc to work correctly with the built-in ethernet on certain Compaq Presario boxes. There are liable to be quite a few people using these as their home systems who might want to try FreeBSD; may as well be nice to them.

Convert the mx driver to miibus. In order to make this work, I created a pseudo-PHY driver to deal with Macronix chips that use the built-in NWAY support and symbol mode port. This is actually all of them, with the exception of the original MX98713 which presents its NWAY support via the MII serial interface. The mxphy driver actually manipulates the controller registers directly rather than using the miibus_readreg()/miibus_writereg() bus interface since there are no MII registers to read. The mx driver itself pretends that the NWAY interface is a PHY locayed at MII address 31 for the sole purpose of allowing the mxphy_probe() routine to know when it needs to attach to a host controller.

Convert the mx driver to miibus. In order to make this work, I created a pseudo-PHY driver to deal with Macronix chips that use the built-in NWAY support and symbol mode port. This is actually all of them, with the exception of the original MX98713 which presents its NWAY support via the MII serial interface. The mxphy driver actually manipulates the controller registers directly rather than using the miibus_readreg()/miibus_writereg() bus interface since there are no MII registers to read. The mx driver itself pretends that the NWAY interface is a PHY locayed at MII address 31 for the sole purpose of allowing the mxphy_probe() routine to know when it needs to attach to a host controller.

Fix some problems reported by Mike Pritchard: - Add a flag DC_TX_INTR_ALWAYS which causes the transmit code to request a TX done interrupt for every packet. The PNIC seems to need this to insure that the sent TX buffers get reaped in a timely fashion. - Try to unreset the SIA as soon as possible after resetting the whole chip. - Change dcphy to support either 10/100 or 10Mbps only NICs. The built-in 21143 ethernet in Compaq Presario machines is 10Mbps only and it doesn't work right if we try to advertise 100Mbps modes during autoneg. When restricted to only 10mbps modes, it works fine. Note that for now, I detect this condition by checking the PCI subsystem ID on this NIC (which has a Compaq vendor/device ID). Yes, I know that's what the SROM is supposed to be for. I'm deliberately ignoring the SROM wherever possible. Sue me. The latter two fixes allow if_dc to work correctly with the built-in ethernet on certain Compaq Presario boxes. There are liable to be quite a few people using these as their home systems who might want to try FreeBSD; may as well be nice to them. Now if anybody out there has an Alpha miata with 10Mbps ethernet and can show me the output from pciconf -l on their system, I'd be grateful.
