This patch adds kdump support to the ehea driver. As the firmware doesn't free
resource handles automatically, the driver has to run an as simple as possible
free resource function in case of a crash shutdown. The function iterates over
two arrays freeing all resource handles which are stored there. The arrays are
kept up-to-date during normal runtime. The crash handler fn is triggered by the
recently introduced PPC crash shutdown reg/unreg functions.

When asked to blink LEDs the tg3 driver behaves when using:
ethtool -p ethX
The default value for data is zero, and other drivers interpret this
as blink forever (or at least a really long time). The tg3 driver
interprets this as blink once. All drivers should have the same
behaviour.

When deleting the veth driver, veth_close calls netif_carrier_off
for the two extremities of the network device. netif_carrier_off on
the peer device will fire an event and hold a reference on the peer
device. Just after, the peer is unregistered taking the rtnl_lock while
the linkwatch_event is scheduled. If __linkwatch_run_queue does not
occurs before the unregistering, unregister_netdevice will wait for
the dev refcount to reach zero holding the rtnl_lock and linkwatch_event
will wait for the rtnl_lock and hold the dev refcount.

This adds printk messages with basic information about the driver being loaded.
This information includes a summary of the compiled-in features, which
simplifies bug-reporting and debugging a lot.
Also a firmware ID is printed. This is a unique identifier blob for a specific
version of the firmware. This ID is attached to a specific version of the firmware
blob in b43-fwcutter (see fwcutter git).
This helps users to select the right firmware for their device.
This also makes it possible to use automated scripts to fetch and extract the right
firmware for the driver. (The script will grep the .ko for the "Firmware-ID: xxx" string.)
While the driver might still support other versions of the firmware for backward
compatibility, this will always print out the officially supported version, which
people _should_ use.

Value of count is used to decide when to replenish rx buffers. If it is
equal or above 8 we replenish the buffers. Ensure there is no starvation
by initializing count to 8 - thus forcing replenish at first iteration.
This is helpful when rx receives batches of buffers smaller than 8.

when setting up the tx descriptors for the hardware we must account for any
padding between the header and the data we might have added previously. frame
len is the length of the frame in the air (including FCS but no padding) and
buffer len is the length of the buffer (including padding, but without FCS).
changing the way ah_setup_tx_desc is called: now excluding the FCS, since it's
easier to add that in the function where we need it.
before this fix we sent trailing zero bytes after the packet (because frame len
included the padding) which was not a big problem without WEP, but with WEP
this resultes in a wrong WEP checksum and the packet is discarded - which is
how i noticed at all ;)
an easy way to run into header padding problems, btw, is to connect to a QoS
(WME) enabled access point (eg. madwifi) - QoS data frames are 2 byte longer
and will require padding.
this patch applies on top of luis latest patch series from 04.02.2008.

In reply to "RE: [Fwd: [PATCH 2.6.25] ixgbe/igb: correctly obtain protocol
information on transmit]" from Andy Gospodarek:
The driver was incorrectly looking at socket headers for
protocol information, needed for checksumming offload. Fix
this by not looking at the socket but frame headers instead.
This disregards extension headers but it's unclear that linux
generates those anyway.

According to one of OOPSes reported by Jann softirq can break

mlx4_table_find (for FMR MPTs) requires that ICM memory already be
mapped. Before this fix, FMR allocation depended on ICM memory
already being mapped for the MPT entry. If all currently mapped
entries are taken, the find operation fails (even if the MPT ICM table
still had more entries, which were just not mapped yet).
This fix moves the mpt find operation to fmr_enable, to guarantee that
any required ICM memory mapping has already occurred.
