* Work around an Intel 21143 chip bug.mckay2002-04-181-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rev 1.56 of if_dc.c removed calls to mii_pollstat() from the dc_tick() routine. dc_tick() is called regularly to detect link up and link down status, especially when autonegotiating. The expectation was that mii_tick() (which is still called from dc_tick()) would update status information automatically in all cases where it would be sensible to do so. Unfortunately, with authentic 21143 chips this is not the case, and the driver never successfully autonegotiates. This is because (despite what it says in the 21143 manual) the chip always claims that link is not present while the autonegotiation enable bit is set. Autonegotation takes place and succeeds, but the driver tests the link bits before it switches off the autonegotiation enable bit, and success is not recognised. The simplest solution is to call dcphy_status() more often for MII_TICK calls by dropping out of the switch statement instead of exiting when we are autonegotiating and link appears to not be present. When autonegotiation succeeds, dcphy_status() will note the speed and fdx/hdx state and turn off the autonegotiation enable bit. The next call to dcphy_status() will notice that link is present, and the dc driver code will be notified. Macronix chips also use this code, but implement link detection as described in the manual, and hence don't need this patch. However, tests on a Macronix 98715AEC-C show that it does not adversely affect them. This could be done better but is the minimal effective change, and most closely mimics what was happening prior to rev 1.56 of if_dc.c. (Actually I also deleted a small amount of unnecessary code while I was in the area.) Reviewed by: wpaul

| | | | | | | | | | adapters. This is necessary in order to make this driver work with the built-in ethernet on the alpha Miata machines. These systems have a 21143-PC chip on-board and optional daughtercards with either a 10/100 MII transceiver or a 10baseT/10base2 transceiver. In both cases, you need to twiddle the GPIO bits on the controller in order to turn the transceivers on, and you have to read the media info from the SROM in order to find out what bits to twiddle.

| | | | | | | | | | | | | | | | | | workalike chips (Macronix 98713A/98715 and PNIC II). Timing is somewhat critical: you need to bring the link as soon as possible after NWAY is done, and the old one second polling interval was too long. Now we poll every 10th of a second until NWAY completes (at which point we return to the 1 second interval again to keep an eye on the link state). I tested all the other cards I had on hand to make sure I didn't bust any of them and they seem to work (including the MII-based 21143 card). This should fix some autoneg problems with DE500-BA cards and the built-in 10/100 ethernet on some alpha systems. (Now before anyone asks why I never noticed this before, the old code worked just find with the Intel swich I used for testing back in NY. Apparently not all switches are as picky about the timing.)

* Fix some problems reported by Mike Pritchard:wpaul1999-12-131-9/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

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.
