[net-2.6 1/7] e1000: add support for Marvell Alaska M88E1118R PHY

[Jeff Kirsher]

From: Florian Fainelli <ffainelli@freebox.fr>

This patch adds support for Marvell Alask M88E188R PHY chips. Support for
other M88* PHYs is already there, so there is nothing more to add than its
PHY id.

[net-2.6 3/7] ixgbe: fix for 82599 erratum on Header Splitting.

[Jeff Kirsher]

From: Don Skidmore <donald.c.skidmore@intel.com>

We have found a hardware erratum on 82599 hardware that can lead to
unpredictable behavior when Header Splitting mode is enabled.  So
we are no longer enabling this feature on affected hardware.

Please see the 82599 Specification Update for more information.

[net-2.6 5/7] ixgbe: DDP last buffer size work around

[Jeff Kirsher]

From: Amir Hanania <amir.hanania@intel.com>

We found a hardware erratum on 82599 hardware that can lead to buffer
overwriting if the last buffer in FCoE DDP is exactly PAGE_SIZE.
If this is the case, we will make sure that there is no HW access to
this buffer.
