ad6c618bc7 Make two major changes to this code to address some stability/corruption
problems:

1) Add locking for SMP, code provided by Alan Cox
2) While testing Alan's patches, I observed serious problems with
   the jumbo buffer allocation code (machine crashed twice), so I gutted
   it and rewrote the receive handler to use multiple chained descriptors.
   Each RX descriptor gets a single 2K cluster, and the chip will fill in
   as many as it needs to hold the complete packet.

User reports that this corrects the data corruption issues previously
observed and discussed on -current.

Note that this driver still needs to be hit with the busdma stick.
I intend to inflict said beating in the near future.

fc4af83ae9 Since if_nge doesn't contain locking or run with INTR_MPSAFE, mark
the interface as IFF_NEEDSGIANT so if_start is run holding Giant.

Note: this driver does declare and occasionally reference mutexes,
but I believe not nearly enough to provide safety.

aa8255025a Try to create some sort of consistency in how the routings to find the
multicast hash are written.  There are still two distinct algorithms used,
and there actually isn't any reason each driver should have its own copy
of this function as they could all share one copy of it (if it grew an
additional argument).

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

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.

- Don't abuse module names to facilitate ifconfig module loading;
  such abuse isn't really needed.  (And if we do need type information
  associated with a module then we should make it explicit and not
  use hacks.)

e808cf6260 When reading PHY regs over the i2c bus, the turnaround ACK bit
is read one clock edge too late. This bit is driven low by
slave (as any other input data bits from slave) when the clock
is LOW. The current code did read the bit after the clock was
driven high again.

d9fc2b816e Do not call nge_tick() if we get an PHY interrupt, nge_tick() calls
mii_tick() which should only be called once per second.

Our current MII/PHY state-engine is not able to deal with PHY
interrupts as far as I can tell, and most net drivers don't seem
to use the link/status change call-back mechanism.  It seems that
MII/PHY was orphaned before it grew up.

ff7ed9f76b If the receiver runs out of space for an received frame in the internal
FIFO or the in-RAM descriptors it will switch to RX_IDLE from where it
is not restarted.

We used to deal with RX_IDLE by doing a total reinit but this lost
our link and caused a potential 30sec autonegotiation against
switches.  This was changed to a less heavyhanded approach, but this
failed to restart the receiver it it were in the RX_IDLE state.

This change adds the RX_IDLE and the RX_FIFO_OFLOW conditions as
triggers for interrupts and receive side processing, and restarts
the receiver when it is RX_IDLE.

Remove the #ifdef notyet'ed nge_rxeoc() function.

8ce3678a09 Handle the RX FIFO overflow condition with the rxeof handler instead
of the rxeoc handler for now. The rxeoc handler will reset the link,
and the NatSemi chip's RX FIFO will overflow on a 32-bit bus once you
start hitting it with 500Mbps or more of traffic.

Also increase the size of the RX ring to 128 descriptors (was 64).
