This patch adds GSO support for IPv6 and TCPv6. This is based on a patch
by Ananda Raju <Ananda.Raju@neterion.com>. His original description is:
This patch enables TSO over IPv6. Currently Linux network stacks
restricts TSO over IPv6 by clearing of the NETIF_F_TSO bit from
"dev->features". This patch will remove this restriction.
This patch will introduce a new flag NETIF_F_TSO6 which will be used
to check whether device supports TSO over IPv6. If device support TSO
over IPv6 then we don't clear of NETIF_F_TSO and which will make the
TCP layer to create TSO packets. Any device supporting TSO over IPv6
will set NETIF_F_TSO6 flag in "dev->features" along with NETIF_F_TSO.
In case when user disables TSO using ethtool, NETIF_F_TSO will get
cleared from "dev->features". So even if we have NETIF_F_TSO6 we don't
get TSO packets created by TCP layer.
SKB_GSO_TCPV4 renamed to SKB_GSO_TCP to make it generic GSO packet.
SKB_GSO_UDPV4 renamed to SKB_GSO_UDP as UFO is not a IPv4 feature.
UFO is supported over IPv6 also
The following table shows there is significant improvement in
throughput with normal frames and CPU usage for both normal and jumbo.
--------------------------------------------------
| | 1500 | 9600 |
| ------------------|-------------------|
| | thru CPU | thru CPU |
--------------------------------------------------
| TSO OFF | 2.00 5.5% id | 5.66 20.0% id |
--------------------------------------------------
| TSO ON | 2.63 78.0 id | 5.67 39.0% id |

Use GSO to workaround a rare TSO bug on some chips. This hardware
bug may be triggered when the TSO header size is greater than 80
bytes. When this condition is detected in a TSO packet, the driver
will use GSO to segment the packet to workaround the hardware bug.
Thanks to Juergen Kreileder <jk@blackdown.de> for reporting the
problem and collecting traces to help debug the problem.
And thanks to Herbert Xu <herbert@gondor.apana.org.au> for providing
the GSO mechanism that happens to be the perfect workaround for this
problem.

Collection of fixes for the ColdFire FEC ethernet driver:
. reworked event setting so that it occurs after the MII setup.
roucaries bastien <roucaries.bastien@gmail.com>
. Do not read cbd_sc in memory for each bit we test. Once per buffer is enough.
. Overrun errors must increase `rx_fifo_errors', not `rx_crc_errors'
. No need for a special value to activate rx or tx. Only write access matters.
. Simplify parameter of eth_copy_and_sum : `data' has already the right value.
. Some spelling fixes.

Symbols such as PCI_USES_IO, PCI_ADDR0, etc. originated from Donald
Becker's net driver template, but have been long unused. Remove.
In a few drivers, this allows the further eliminate of the pci_flags (or
just plain flags) member in the template driver probe structure.
Most of this logic is simply open-coded in most drivers, since it never
changes.
Made a few other cleanups while I was in there, too:
* constify, __devinitdata several PCI ID tables
* replace table terminating entries such as "{0,}," and "{NULL},"
with a more-clean "{ }".

* make eeprom size a variable, prepping for future patch
* eliminate unused PCI_xxx stuff left over from Becker driver template
* convert a few #defines to enum

dev_setup() is using the __initdata variables ax25_broadcast and
ax25_test.
Since the only caller of dev_setup() (setup_adapter()) is already
__init, the solution is to make dev_setup() __init, too.

off the revision number. This driver does not shift, so the id and mask
values are wrong and must be left shifted by 4 to actually detect the chips.

The DM9000 driver does not deal with the case
where there is no serial EEPROM to store the
configuration, and the bootloader has placed
an MAC address into the device already.
If there is no valid MAC in the EEPROM, read
the one already in the chip and check to see
if that one is valid.

The current DM9000 driver cannot cope if it
is given more than 3 resources (for example, if

not using yet).
Check that we have been given at-least one IRQ
resource.
Also fix the minor type-casting for the case
of 2 resources.
