Nick Nunley 757b77e2b2 igb: add per-packet timestamping
This patch adds support for per-packet timestamping for the
82580 adapter. The rx timestamp code is also pulled out of the
inlined rx hotpath and instead moved to a seperate function.

This version adds a comment explaining the per-packet timestamping
code added to igb_hwtstamp_ioctl().

Alexander Duyck 28fc06f58b igb: move all multicast addresses into multicast table array
This patch moves all of the multicast addresses out of the free Receive
address registers and instead programs them all into the multicast table
array.  As a result the multicast filtering may not be as precise, but it
also greatly reduces the overhead for multicast addresses.

Alexander Duyck 099e1cb700 igb: make serdes power down available for 82575 in addition to 82576 parts
There was a serdes power down workaround that was originally added for
82576 fiber.  However it has also been found that this workaround is needed
for serdes connections as well.  In addition it is also needed for 82575
serdes so we we need to remove the checks restricting it to 82576.

Jesse Brandeburg b9473560c6 igb: Enable SCTP checksum offloading
Originally from: Vlad Yasevich <vladislav.yasevich@hp.com>

This patch, both the driver portion and the sctp code was
modified by Jesse Brandeburg and is

Copyright(c) 2009 Intel Corporation.

Thanks go to Vlad for starting this work.

Intel 82576 chipset supports SCTP checksum offloading.  This
patch enables this functionality in the driver.  A new NETIF
feature is introduced for SCTP checksum offload.  If the driver
supports CRC32c checksum, it can set this feature flag.  The
hardware can offload both transmit and receive.

Patrick Ohly 33af6bcc00 igb: use timecompare to implement hardware time stamping
Both TX and RX hardware time stamping are implemented.  Due to
hardware limitations it is not possible to verify reliably which
packet was time stamped when multiple were pending for sending; this
could be solved by only allowing one packet marked for hardware time
stamping into the queue (not implemented yet).

RX time stamping relies on the flag in the packet descriptor which
marks packets that were time stamped. In "all packet" mode this flag
is not set. TODO: also support that mode (even though it'll suffer
from race conditions).

Alexander Duyck 8a900862a2 igb: rename igb_update_mc_addr_list_82575 to not include the 82575
There isn't much point in having the _82575 hanging off the end of this
function since there aren't any other version of this function running
around within this driver.  This also allows for a bit of whitespace
cleanup due to a shorter function name.

Auke Kok 9d5c824399 igb: PCI-Express 82575 Gigabit Ethernet driver
We are pleased to announce a new Gigabit Ethernet product and its
driver to the linux community. This product is the Intel(R) 82575
Gigabit Ethernet adapter family. Physical adapters will be available
to the public soon. These adapters come in 2- and 4-port versions
(copper PHY) currently. Other variants will be available later.

The 82575 chipset supports significantly different features that
warrant a new driver. The descriptor format is (just like the
ixgbe driver) different. The device can use multiple MSI-X vectors
and multiple queues for both send and receive. This allows us to
optimize some of the driver code specifically as well compared to
the e1000-supported devices.

This version of the igb driver no lnger uses fake netdevices and
incorporates napi_struct members for each ring to do the multi-
queue polling. multi-queue is enabled by default and the driver
supports NAPI mode only.

All the namespace collisions should be gone in this version too. The
register macro's have been condensed to improve readability.
