and DP83821 gigabit ethernet MAC chips and the NatSemi DP83861 10/100/1000
copper PHY. There are a whole bunch of very low cost cards available with
this chipset selling for $150USD or less. This includes the SMC9462TX,
D-Link DGE-500T, Asante GigaNIX 1000TA and 1000TPC, and a couple cards
from Addtron.
This chip supports TCP/IP checksum offload, VLAN tagging/insertion.
2048-bit multicast filter, jumbograms and has 8K TX and 32K RX FIFOs.
I have not done serious performance testing with this driver. I know
it works, and I want it under CVS control so I can keep tabs on it.
Note that there's no serious mutex stuff in here yet either: I need
to talk more with jhb to figure out the right way to do this. That
said, I don't think there will be any problems.
This driver should also work on the alpha. It's not turned on in
GENERIC.
a LinkSys card here in the office where reading the station address
fails the first time, but works find afterwards. Without this, the
probe fails. I don't think this will negatively impact any existing
cards, but I want to confirm this before MFC'ing.
we need to delete the info from the list as well as zero out the res
pointer we saved in the code.
Also made a few style(9) changes while I was at it. Don't use if
(ptr) or if (!ptr), but compare against NULL. Compare against NULL
rather than 0. Don't have useless blocks.
There are likely other problems as well, but at least the wi based
wireless card with memory listed in its cis doesn't panic the system
when the card is inserted.
use TAILQ macros. The sk_attach_xmac() routine calls sk_init_xmac()
before doing the transceiver probe, but *before* ether_ifattach()
is called. This causes sk_init_xmac() to call sk_setmulti(), which
tries to do a TAILQ_FOREACH(), which it can't do because ether_ifattach()
hasn't done a TAILQ_INIT() yet. This causes a NULL pointer dereference
and panic in sk_setmulti() at driver load/initialization time.
Fixed by calling ether_ifattach() before the MII probe.
The code in RELENG_4 still uses the old way of enumerating the
multicast list and doesn't have this problem. Yet.
Reduce the verbose memory map setup reports and work with pccardd to
set the common memory map up.
Use enumeration values for CARD_SET_RES_FLAGS.
Use DELAY when spinning waiting for the card to come free instead of a loop.
MFC: after 1 week
Tidy up includes, credit Slawa Olhovchenkov, John Prince and Eric Hernes
for their efforts and add a couple of missing parenthesis around return
expressions.
- Rework of twe_report_request to use the command status value rather
than the flags register. (Joel Jacobson @ 3ware)
- Update to match some changes in -current vs. stable.
MFC in: 1 week
This driver supports PCI Xr-based and ISA Xem Digiboard cards.
dgm will go away soon if there are no problems reported. For now,
configuring dgm into your kernel warns that you should be using
digi. This driver is probably close to supporting Xi, Xe and Xeve
cards, but I wouldn't expect them to work properly (hardware
donations welcome).
The digi_* pseudo-drivers are not drivers themselves but contain
the BIOS and FEP/OS binaries for various digiboard cards and are
auto-loaded and auto-unloaded by the digi driver at initialisation
time. They *may* be configured into the kernel, but waste a lot
of space if they are. They're intended to be left as modules.
The digictl program is (mainly) used to re-initialise cards that
have external port modules attached such as the PC/Xem.
other "system" header files.
Also help the deprecation of lockmgr.h by making it a sub-include of
sys/lock.h and removing sys/lockmgr.h form kernel .c files.
Sort sys/*.h includes where possible in affected files.

The constant I was using was correct, but I mislabeled it as 256K when
it should have been 512K. This doesn't actually change the code, but
it clarifies things somewhat.

Add TI4451 as well.
These are untested since I don't have the hardware to test against.
Also, some O2Micro devices are #define w/o numbers as place holders so that
I can encourage people to submit them when they appear in the channels.
