d147662cd3 - Fix VLAN_INPUT_TAG() macro, so that it doesn't touch mtag in
case if memory allocation failed.
- Remove fourth argument from VLAN_INPUT_TAG(), that was used
  incorrectly in almost all drivers. Indicate failure with
  mbuf value of NULL.

4a0d6638b3 - Store pointer to the link-level address right in "struct ifnet"
rather than in ifindex_table[]; all (except one) accesses are
  through ifp anyway.  IF_LLADDR() works faster, and all (except
  one) ifaddr_byindex() users were converted to use ifp->if_addr.

- Stop storing a (pointer to) Ethernet address in "struct arpcom",
  and drop the IFP2ENADDR() macro; all users have been converted
  to use IF_LLADDR() instead.

1ec14c6ee9 Remove call to txp_set_filter() from txp_attach(). txp_set_filter() needs
the ifp, so you can't call it before doing if_alloc(). Also, there's
really no need to call it here anyway: the code I originally ported from
OpenBSD incorrectly set the station address only once at device attach
time, instead of setting in txp_init(). This meant you couldn't change
the address with ifconfig txp0 ether xx:xx:xx:xx:xx:xx. I added the
call to txp_set_filter() in txp_init() to correct this, but forgot to
remove the call from txp_attach(). Until now, it never mattered.

With this fix, the txp driver tests good:

txp0: <3Com 3cR990-TX-97 Etherlink with 3XP Processor> port 0xb800-0xb87f mem 0xe6800000-0xe683ffff irq 12 at device 10.0 on pci0

2bf266e6da - Add locking and mark MPSAFE. The driver had a mutex in the softc and
even initialized it, but it never used it.
- Use callout_*() to manage the callout.
- Use m_devget() to copy data out of the rx buffers rather than doing it
  all by hand.
- Use m_getcl() to allocate mbuf clusters rather than doing it all by hand.
- Don't free the software descriptor for a rx ring entry if we can't
  allocate an mbuf cluster for it.  We left a dangling pointer and never
  reallocated the entry anyway.  OpenBSD's code (from which this was
  derived) has the same bug.

ad4f426ef6 Make sure that we call if_free(ifp) after bus_teardown_intr. Since we
could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash.  Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

095f2ac443 Since if_txp doesn't contain locking or run with INTR_MPSAFE, mark
the interface as IFF_NEEDSGIANT so if_start is run holding Giant.

Note: mutexes are initialized in the softc for this driver, but the
locking appears inadequate to allow Giant-free operation.

fa4b32fa80 All current uses of pci_set_powerstate are bogus, at least in theory.
However, they are presently necessary due to bigger bogusness in the
pci bus layer not doing the right thing on suspend/resume or on
initial device probe.  This is exactly the sort of thing that the
BURN_BRIDGES option was invented for.  Mark all of them as
BURN_BRIDGES.  As soon as I have the powerstate stuff properly
integrated into the pci bus code, I intend to remove all these
workarounds.

362c5c1e02 You were knocked senseless by the Boomerang, spun around by the Cyclone,
blown over by the Hurricane and had a house dropped on you by the Tornado.
Now it's time to have your parade rained on by... the Typhoon!

This commit adds driver support for 3Com 3cR990 10/100 ethernet
adapters based on the Typhoon I and Typhoon II chipsets. This is actually
a port of the OpenBSD driver with many hacks by me.

No Virginia, there isn't any support for the hardware crypto yet. However
there is support for TCP/IP checksum offload and VLANs.

Special thanks go to Jason Wright, Aaron Campbell and Theo de Raadt for
squeezing enough info out of 3Com to get this written, and for doing
most of the hard work.

Manual page is included. Compiled as a module and included in GENERIC.
