      igb: Replace LRO with GRO · 5c0999b7
      由 Herbert Xu 提交于 
      This patch makes igb invoke the GRO hooks instead of LRO.  As
GRO has a compatible external interface to LRO this is a very
straightforward replacement.

Three things of note:

1) I've kept the LRO Kconfig option until we decide to enable
GRO across the board at which point it can also be killed.

2) The poll_controller stuff is broken in igb as it tries to do
the same work as the normal poll routine.  Since poll_controller
can be called in the middle of a poll, this can't be good.

I noticed this because poll_controller can invoke the GRO hooks
without flushing held GRO packets.

However, this should be harmless (assuming the poll_controller
bug above doesn't kill you first :) since the next ->poll will
clear the backlog.  The only time when we'll have a problem is
if we're already executing the GRO code on the same ring, but
that's no worse than what happens now.

3) I kept the ip_summed check before calling GRO so that we're
on par with previous behaviour.

      netdevice: safe convert to netdev_priv() #part-2 · 4cf1653a
      由 Wang Chen 提交于 
      We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

This patch is a safe convert for netdev->priv to netdev_priv(netdev).
Since all of the netdev->priv is only for read.
But it is too big to be sent in one mail.
I split it to 4 parts and make every part smaller than 100,000 bytes,
which is max size allowed by vger.

      igb: PCI-Express 82575 Gigabit Ethernet driver · 9d5c8243
      由 Auke Kok 提交于 
      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.
