Reduce the size of ed a little by removing some CIS based entries (others
likely can be removed too):
o The D-Link DFE-670TXD doesn't need its own entry based on strings.
o The Xircom CompactCard appears to be a TDK design, so list it there by ID
and remove the strings.
Increase the size of ed a little:
o Add support for the Addtron AE-660CT and Addtron AE-660. This is a very
generic NE-2000 clone (so generic that its CIS tags say NE-2000 generic
card!).
here is the support for amd64, as well as possible support for PAE. Many
thanks to Highpoint for continuing to support FreeBSD.

o Note that the first 255 locations are reserved for JEDEC Ids from
publication 106 (current revision Q, each one verified with

o Move ADAPTEC2 to the right section.
o Sort TOSHIBA2 numerically.
dl100xx case.
o We no longer acquire and release resources during attach many times. We now
do it once at the beginning.
o Move setting the resource offsets to just after acquiring the ports in
attach.
o Move ax88x90 code to the end of the file, just after the dl100xx specific
code.
o Rename ed_pccard_Linksys to ed_pccard_dl100xx to reflect the underlying
chipset.
o Pass the ed_product structure into ed_pccard_{dl100xx,ax88x90} and have
those routines test the flags to see if this card should be probed in that
way.
o transition from ed_probe_Novell to ed_probe_Novell_generic since we already
have the resources setup.
o Move use of ed_probe_Novell_generic into ed_pccard_dl100xx to be more
consistant with ax88x90 case.
o simplify the code where we probe for the chipsets
the probe code that this used to be part of, but as part of the
attach, we shouldn't be dropping the resources here.
Also, allocate the proper rid in the ax88x90 setup.
as yet unknown, those cards report their MAC address a byte at a time.
However, other AX88x90 cards report the MAC address a word at a time.
Add a heuristic which looks at the high order bytes of the first 6
words. If they are all '0', assume the card is behaving like the
Linksys EC2T card. Since the default prefix for these cards appears
to be 00:e0:98, this appears to be a safe heuristic. While some cards
have been observed with different prefixes, they all work with this
heuristic.
I'm unsure if this is a bug in the EC2T card, or if it is a bug in the
initialization of the card. No other OS has this heuristic (although
w/o it, the MAC address that is used works).
listed in different orders. Since it is easy to identify the Modem
resources vs the Ethernet resources by looking at the size, use that
rather than hard coded rids. For such parts, go ahead and guess which
rid we should use based on the size. This guess appears reliable for
the two example cards that I have with different CIS info.
return the correct bar size if we encountered a 64-bit BAR that had
its resources already assigned. If the resources weren't yet
assigned, we'd bogusly assume it was a 32-bit bar and return 1.
PROM by bytes. Adjust the extraction of the MAC address from this data
to reflect this change.
This gets the AX88x90 based PC Cards MAC address working again (my
UMAX Ethernet and Linksys EC2T cards now work).

- On resume all registers have to be initialized again like after
power-on so reset sc_inited in gem_suspend() in order get all of
the registers set next time gem_init_regs() is called.
- On at least some ERI and GEM revisions GEM_MAC_RX_OVERFLOW happen
often due to a silicon bug and re-initializing is all we can do
about these errors so make handling them non-verbose.
- Remove a superfluous memset(3) call in gem_meminit(), all elements

tulip_mbuf_compress(). If we fail to allocate a new mbuf to copy the
data into, put the mbuf back in the driver's send queue so that we can
retry it later rather than throwing the packet away.
- Use m_devget() instead of doing it inline ourselves in the
TULIP_COPY_RXDATA case. If we fail to allocate an mbuf to copy the data
into, don't forget about the original mbuf cluster. The old code would
lose the pointer and leak the cluster in that case. Now it doesn't lose
it but always sticks the original rx buffer back into the receive ring
after trying to copy the data out and send it up the stack. Also, if we
fail to allocate a new mbuf to copy the data into, log an input error.
Also, don't combine the priming case with the received-a-packet case to
make the code flow a bit clearer and easier to follow.
not exsist, do not have ioctl return an error, but instead set -1

- Remove form feed characters.
- Fixup style of function declarations.
- Assume that an mbuf cluster is big enough to hold an ethernet frame.
(This should really be using m_defrag(), but this diff is just simple
changes for now.)
- Allocate arrays of metadata for the descriptors in the rx and tx rings
and change the ring pointers to walk the metadata array rather than the
actual descriptor rings. Each metadata object contains a pointer to its
descriptor, a pointer to any associated mbuf, and a pointer to the
associated bus_dmamap_t in the bus_dma case. The mbuf pointers replace
the tulip_txq and tulip_rxq local ifqueue's in the softc.
- Add lots of KTR trace entries using a local KTR_TULIP level which
defaults to 0, but can be changed to KTR_DEV at the top of the file
when debugging.
- Rename tulip_init(), tulip_start(), tulip_ifinit(), and tulip_ifstart()
to tulip_init_locked(), tulip_start_locked(), tulip_init(), and
tulip_start(), respectively, to match the convention in other drivers.
- Add a TULIP_SP_MAC() macro to encode two bytes of the MAC address into
the setup buffer and use that in place of lots of BYTE_ORDER #ifdef's.
Also, remove an incorrect XXX comment I added earlier, the driver was
correct (at least it does the same thing dc(4) does). TULIP_SP_MAC
was shamelessly copied from DC_SP_MAC() in dc(4).
- Remove the #ifdef'd NetBSD bus-dma code and replace it with FreeBSD
bus-dma code that not only compiles but even works at runtime.
- Use callout_init_mtx() instead of just callout_init().
- Correct the various wrapper macros for bus_dmamap_sync() for the rx
and tx buffers to only ask for the sync ops that they actually need.
- Tidy the #ifdef TULIP_COPY_RXDATA code by expanding an #ifdef a bit
so it becomes easier to read at the expense of a couple of duplicated
lines of code. Also, use m_getcl() to get an mbuf cluster rather than
MGETHDR() followed by MCLGET().
- Maintain the ring free (ri_free) count for the rx ring metadata since
we no longer have tulip_rxq.ifq_len around to indicate how many mbuf's
are currently in the rx ring.
- Add code to teardown bus_dma resources when attach fails and generally
fixup attach to do a better job of cleaning up when it fails. This
gets us a good bit closer to possibly having a detach method someday
and making this driver an unloadable module.
- Add some functions that can be called from ddb to dump the state of
a descriptor ring and to dump the state of an individual descriptor.
- Various comment grammer and spelling fixes.
I have bus-dma turned on by default, but I've left the non-bus-dma code
around so that it can be turned off to aid in debugging should any problems
turn up later on. I'll be removing the non-bus-dma code in a subsequent
commit.
