the interface to use callout_* instead of timeout(). Also add an
IS_MPSAFE #define (currently off) which will mark the driver as mpsafe
to the upper layers.
a RealTek 8139 cardbus device. Unfortunately it doesn't quite work yet
because the CIS parser barfs on it.
Submitted by msmith, with some small tweaks by me.
This commit adds support for Xircom X3201 based cardbus cards.
Support for the TDK 78Q2120 MII is also added.
IBM Etherjet, Intel and Xircom cards uses these chips.
Note that as a result of this commit, some Intel/DEC 21143 based cardbus
cards will also attach, but not get link. That is being looked at.
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.
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.
on the NEC VersaPro NoteBook PC. This 21143 implementation has no LEDs,
and flipping the LED control bits somehow stops it from establishing
a link. We check the subsystem ID and don't flip the LED control
bits for the NEC NIC.
3.3volt PCI/cardbus chipsets similar to the 98715 (and they have
512-bit hash tables). Also update the man page to mention the 98727/98732
and the SOHOware SFA110A Rev B4 card with the 98715AEC-C chip.
which differ slightly from the Macronix MX98715AEC chip on the sample
adapter that I have in that the multicast hash table is only 128 bits
wide instead of 512. New adapters are popping up with this chip, and
due to improper handling of the smaller hash table, broadcast packets
were not being received correctly.
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.)
This is just to make sure we initialize the chip correctly: we need to
make the sure the port select bit in CSR6 is set properly so that we
use the internal PHY for 10/100 support. (The eval boards I have also
include an external HomePNA PHY, but I need to play with that more
before I can support it.)
- 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.
