From: PJ Waskiewicz <peter.p.waskiewicz.jr@intel.com>
This patch adds the hardware initialization code specific to 82599. This
is similar to the 82598 hardware initialization code. It also includes all
changes to the existing hardware init code to support 82599.

Thanks for the comments Ben. Early on, we looked at doing this. The
reality though for us is this code (the PHY code, among others) is shared
between our drivers across different platforms. So the reason we didn't
use the in-kernel I2C library is nobody else would have been able to use the
code. But that doesn't really apply to this driver; just wanted to give
background why this is the way it is in the post.
That being said, I will look at the I2C kernel interfaces this weekend and
see how I can fit it in here.
Cheers,

To: davem; +Cc: netdev, gospo, Peter P Waskiewicz Jr, Jeff Kirsher
From: PJ Waskiewicz <peter.p.waskiewicz.jr@intel.com>
This patch adds the DCB (Data Center Bridging) support for 82599 hardware.
This is similar to how the 82598 DCB code works.
This patch also removes the BCN (Backwards Congestion Notification) netlink
configuration code from the driver. BCN was a pre-standard congestion
notification framework, and was not what the IEEE body decided upon for
standard congestion management. QCN (802.1Qau), Quantized Congestion
Notification is the accepted standard, which is not supported by 82599,
hence we remove the support altogether.

From: Jeff Kirsher @ 2009-02-28 1:45 UTC (permalink / raw)
To: davem; +Cc: netdev, gospo, Peter P Waskiewicz Jr, Jeff Kirsher
From: PJ Waskiewicz <peter.p.waskiewicz.jr@intel.com>
With the hardware-specific code in place, add all supported device id's,
along with base driver changes to enable 82599 devices. The devices
being enabled are:
8086:10f7: 82599EB 10 Gigabit KX4 Network Connection
8086:10fb: 82599EB 10 Gigabit Network Connection
The device 8086:10fb is a fully-pluggable SFP+ NIC.

Thanks Dave.
I know that PJ is actively working with Ben to see how we can
implement the in kernel I2C interface into the driver.

Yes, Ben has helped quite a bit pointing me in the right direction. I'll
be cleaning up both the 82599 I2C usage, and I'll try and clean up the
existing 82598 I2C usage at the same time.
Cheers,
