041b706b2f Despite several examples in the kernel, the third argument of
sysctl_handle_int is not sizeof the int type you want to export.
The type must always be an int or an unsigned int.

Remove the instances where a sizeof(variable) is passed to stop
people accidently cut and pasting these examples.

In a few places this was sysctl_handle_int was being used on 64 bit
types, which would truncate the value to be exported.  In these
cases use sysctl_handle_quad to export them and change the format
to Q so that sysctl(1) can still print them.

08013fd336 - Add support/quirks for the on-board BGEs found in Sun Blade 1500
Blade 2500, Fire V210 and probably some other sparc64 machines.
  These chips are typically not fitted with an EEPROM which means
  that we have to obtain the MAC address via OFW and that some chip
  tests will just always fail.
  These changes are based on the respective code found in OpenBSD
  with some additional info obtained from OpenSolaris and some style
  suggestions by jkim@. They also have the desired side-effect of
  respecting the 'local-mac-address?' system configuration variable
  for the affected BGEs.
- In bge_attach() factor out calling bge_release_resources() before
  going to the fail label into the fail label as well as replace a
  magic 6 with ETHER_ADDR_LEN.

b64728e55e After rev.1.169, the "interrupt" coalescing parameters are not used in
bge_intr().  Some of them are used in bge_poll().  Simplify by only
initializing these for polling mode and not toggling them when switching
modes.  This also fixes missing synchronization with the coalescing
engine in the toggling.

5b01e77c64 In bge_txeof(), cancel the watchdog timeout if all descriptors have
been handled instead of when at least one descriptor was just handled.
For bge, it is normal to get a txeof when only a small fraction of the
queued tx descriptors have been handled, so the bug broke the watchdog
in a usual case.

b848e03260 Avoid a race and a pessimization in bge_intr():
- moved the synchronizing bus read to after the bus write for the first
  interrupt ack so that it actually synchronizes everything necessary.

  We were acking not only the status update that triggered the interrupt
  together with any status updates that occurred before we got around
  to the bus write for the ack, but also any status updates that occur
  after we do the bus write but before the write reaches the device.
  The corresponding race for the second interrupt ack resulted in
  sometimes returning from the interrupt handler with acked but
  unserviced interrupt events.  Such events then remain unserviced
  until further events cause another interrupt or the watchdog times
  out.

  The race was often lost on my 5705, apparently since my 5705 has broken
  event coalescing which causes a status update for almost every packet,
  so another status update is quite likely to occur while the interrupt
  handler is running.  Watchdog timeouts weren't very noticeable,
  apparently because bge_txeof() has one of the usual bugs resetting the
  watchdog.

- don't disable device interrupts while bge_intr() is running.  Doing this
  just had the side effects of:
  - entering a device mode in which different coalescing parameters apply.
    Different coalescing parameters can be used to either inhibit or
    enhance the chance of getting another status update while in the
    interrupt handler.  This feature is useless with the current
    organization of the interrupt handler but might be useful with a
    taskqueue handler.
  - giving a race for ack+reenable/return.  This cannot be handled
    by simply rearranging the order of bus accesses like the race for
    ack+keepenable/entry.  It is necessary to sync the ack and then
    check for new events.
  - taking longer, especially with the extra code to avoid the race on
    ack+reenable/return.

088766f15c Remove a redundant write of the firmware reset magic number. It looks to

- Program the descriptor DMA engine correctly.

6b037352d0 - Correct collision counter for BCM5705+. This register is read/clear.
- Correct RX packet drop counter for BCM5705+.  This register is read/clear
and it wraps very quickly under heavy packet drops because only the lower
ten bits are valid according to the documentation.  However, it seems few
more bits are actually valid and the rest bits are always zeros[1].
Therefore, we don't mask them off here.  To get accurate packet drop count,
we need to check the register from bge_rxeof().  It is commented out for now,
not to penalize normal operation.  Actual performance impact should be
measured later.
- Correct integer casting from u_long to uint32_t.  Casting is not really
needed for all supported platforms but we better do this correctly[2].
