The legacy jumbo frame receive code is no longer needed since all
hardware can do packet split and we're no longer offering a bypass
kernel config option to disable packet split. Remove the unused code.

This workaround code performed software stripping instead of the
hardware which can do it much faster. None of the e1000e target
hardware has issues with this feature and should work fine. This
gives us some performance back on receive, and removes some
kludging stripping the 4 bytes.

Upon inspection the rx FIFO size calculation code was found to have
2 significant flaws: A superfluous minus sign resulting in the
wrong size to be used for jumbo frames on 82573 and ich9, as well
as that this code rewrote the read-only adapter->pba variable
resulting in different values at each run.
Without this patch jumbo's will work but performance will be
awkward since the TX size is not adequate for two whole frames.

Fix allocation and freeing of jumbo frames where several bugs
were recently introduced by cleanups after we forked this code
from e1000. This moves ps_pages to buffer_info where it really
belongs and makes it a dynamically allocated array. The penalty
is not that high since it's allocated outside of the buffer_info
struct anyway.
Without this patch all jumbo frames are completely broken and the
driver panics.

After a cable unplug the forced flow control settings were lost
accidentally and the flow control settings fell back to the default
EEPROM determined values. This breaks for people who want to
run without fc enabled - after a cable reset the driver would
refuse to run with fc disabled.

A small bug crawled in the -DDEBUG enabled code. Fix this to

Returning BUSY will make qdisc_restart enqueue the skb which was already
freed. The bad skb was correctly freed and we should return NETDEV_TX_OK.

It's been a useless no-op for long enough in 2.6 so I figured it's time to
remove it. The number of people that could object because they're
maintaining unified 2.4 and 2.6 drivers is probably rather small.

This driver implements support for the ICH9 on-board LAN ethernet
device. The device is similar to ICH8.
The driver encompasses code to support 82571/2/3, es2lan and ICH8
devices as well, but those device IDs are disabled and will be
"lifted" from the e1000 driver over one at a time once this driver
receives some more live time.
Changes to the last snapshot posted are exclusively in the internal
hardware API organization. Many thanks to Jeff Garzik for jumping in
and getting this organized with a keen eye on the future layout.
