This patch adds skb_recycle_check(), which can be used by a network
driver after transmitting an skb to check whether this skb can be
recycled as a receive buffer.
skb_recycle_check() checks that the skb is not shared or cloned, and
that it is linear and its head portion large enough (as determined by
the driver) to be recycled as a receive buffer. If these conditions
are met, it does any necessary reference count dropping and cleans
up the skbuff as if it just came from __alloc_skb().

With 2.6.27-rc3 I noticed the following messages in my boot log:

0000:01:00.0: eth0: (PCI Express:2.5GB/s:Width x1) 00:16:76:04:ff:09
The second seems correct, but the first has a silly repetition of the
PCI device before the actual message. The message originates from
e1000_eeprom_checks in e1000e/netdev.c.
With this patch below the first message becomes
e1000e 0000:01:00.0: Warning: detected DSPD enabled in EEPROM
which makes it similar to directly preceding messages.
Use dev_warn instead of e_warn in e1000_eeprom_checks() as the interface
name has not yet been assigned at that point.

Removing the module would cause a kernel oops as platform_driver_probe
failed to detect a device and unregistered the platform driver on module
init, and cleanup_module would unregister the already unregistered driver.
The suspend and resume functions weren't being called.
platform_driver support was added earlier, but without any
platform_device_register* calls I don't think it was being used. Now all
devices are registered using platform_device_register_simple and pointers
are kept to unregister the ones that the probe failed for or unregister
all devices on module shutdown. init_module no longer calls ne_init to
reduce confusion (and multiple unregister paths that caused the rmmod
oops). With the devices now registered they are added to the platform
driver and get suspend and resume events.
netif_device_detach(dev) was added before unregister_netdev(dev) when
removing the region as occationally I would see a race condition where the
device was still being used in unregister_netdev.

The loop with the timeout used "while (... && timeout--)", which means
than when the timeout occurs, "timeout" will be -1 after the loop has
exited. The code that checks if the looped exited because of a timeout
used "if (timeout <= 0)". Seems ok, except timeout is unsigned, and
(unsigned)-1 isn't less than zero!
Using "--timeout" in the loop fixes this problem, as now "timeout" will be
0 when the loop times out.
This also fixes a bug in the existing code, where it will erroneously think
a timeout occurred if the condition the loop was waiting for is satisfied
on the final iteration before a timeout.
