Some devices identify themselves as a virtual USB CDROM drive. The virtual CD
includes the windows driver. We aren't interested in this, so we eject the
virtual CDROM and then the real wireless device appears.

Patch fixed over the earlier version to not leak cmd, thanks to Michael Buesch
for spotting that.

This is needed for my G220F, otherwise it fails to initialize after the
existing firmware upload routine.

The vendor driver actually does more than what I have done here: it
downloads the firmware + boot code, modifies it, and uploads it again
(really messy). I have not copied that part over, as my device can get
on its feet without it.

Fix a subtle race condition between tg3_start_xmit() and tg3_tx()
discovered by Herbert Xu <herbert@gondor.apana.org.au>:

CPU0					CPU1
tg3_start_xmit()
	if (tx_ring_full) {
		tx_lock
					tg3_tx()
						if (!netif_queue_stopped)
		netif_stop_queue()
		if (!tx_ring_full)
						update_tx_ring 
			netif_wake_queue()
		tx_unlock
	}

Even though tx_ring is updated before the if statement in tg3_tx() in
program order, it can be re-ordered by the CPU as shown above.  This
scenario can cause the tx queue to be stopped forever if tg3_tx() has
just freed up the entire tx_ring.  The possibility of this happening
should be very rare though.

The following changes are made:

1. Add memory barrier to fix the above race condition.

2. Eliminate the private tx_lock altogether and rely solely on
netif_tx_lock.  This eliminates one spinlock in tg3_start_xmit()
when the ring is full.

3. Because of 2, use netif_tx_lock in tg3_tx() before calling
netif_wake_queue().

4. Change TX_BUFFS_AVAIL to an inline function with a memory barrier.
Herbert and David suggested using the memory barrier instead of
volatile.

5. Check for the full wake queue condition before getting
netif_tx_lock in tg3_tx().  This reduces the number of unnecessary
spinlocks when the tx ring is full in a steady-state condition.

6. Update version to 3.65.

Rewrite of the bcm43xx initialization routines.
This fixes several issues:
* up-down-up-down-up... stale data issue
  (May fix some DHCP issues)
* Fix the init vs IRQ handler race (and remove the workaround)
* Fix init for cards with multiple cores (APHY)
  As softmac has no internal PHY handling (unlike dscape),
  this adds the file "phymode" to sysfs.
  The active PHY can be selected by writing either a, b or g
  to this file. Current PHY can be determined by reading from it.
* Fix the controller restart code.
  Controller restart can now also be triggered through
  echo 1 > /debug/bcm43xx/ethX/restart
