Peter P Waskiewicz Jr 264857b8fe ixgbe: Allow link flow control in DCB mode for 82599 adapters
82599 supports using either link flow control or priority flow control when
in DCB mode.  The dcbnl interface already supports sending down
configurations through rtnetlink that can enable LFC when DCB is enabled,
so the driver should take advantage of this.

82598 does not support using LFC when DCB is enabled, so explicitly disable
it when we're in DCB mode.  This means we always run in PFC mode when DCB
is enabled.

PJ Waskiewicz bb3daa4a59 ixgbe: Allow Priority Flow Control settings to survive a device reset
When changing DCB parameters, ixgbe needs to have the MAC reset.  The way
the flow control code is setup today, PFC will be disabled on a reset.
This patch adds a new flow control type for PFC, and then has the netlink
layer take care of toggling which type of flow control to enable.

Peter P Waskiewicz Jr 0ecc061d19 ixgbe: Update flow control state machine in link setup
The flow control handling is overly complicated and difficult to maintain.
This patch cleans up the flow control handling and makes it much more
explicit.  It also adds 1G flow control autonegotiation, for 1G copper
links, 1G KX links, and 1G fiber links.

Peter P Waskiewicz Jr 3efac5a001 ixgbe: Update copyright dates, bump the driver version number
New year, new copyright date ranges.  Also bump the driver version
number to reflect many of the recent changes.

Alexander Duyck 2f90b8657e ixgbe: this patch adds support for DCB to the kernel and ixgbe driver
This adds support for Data Center Bridging (DCB) features in the ixgbe
driver and adds an rtnetlink interface for configuring DCB to the
kernel.  The DCB feature support included are Priority Grouping (PG) -
which allows bandwidth guarantees to be allocated to groups to traffic
based on the 802.1q priority, and Priority Based Flow Control (PFC) -
which introduces a new MAC control PAUSE frame which works at
granularity of the 802.1p priority instead of the link (IEEE 802.3x).
