Don Skidmore 5e655105e3 ixgbe: add function pointer for semaphore function
The X540 devices grabs semaphores differently than 82599 and 82598
devices do.  They do however also grab them in allot of the same
functions.  So I'm adding a new MAC operation function pointer to
allow us to use the correct function based on our MAC type.  I'm also
changing all the semaphore calls to use this new function pointer.

Emil Tantilov 75f19c3c5e ixgbe: cleanup handling of I2C interface to PHY
The I2C interface was not being correctly locked down per port.  As such

up the handling to make certain we are not experiencing racy I2C access.

Mallikarjuna R Chilakala 119fc60a2d ixgbe:add support for a new 82599 10G Base-T device
This adds support for a new copper device for 82599, device id 0x151c.
This 82599 10GBase-T device uses the PHY's internal temperature sensor
to guard against over-temp conditions. In this scenario the PHY will be
put in a low power mode and link will no longer be able to transmit or
receive any data. When this occurs, the over-temp interrupt is latched
and driver logs this error message. A HW reset or power cycle is
required to clear this status.

Don Skidmore 63d6e1d80a ixgbe: fix issues with failing to detect insert of unsupported module
Several small fixes around negative test case of the insertion of a
IXGBE_ERR_NOT_SUPPORTED module.

- mdio45_probe call was always failing due to mdio.prtad not being
set.  The function set to mdio.mdio_read was still working as we just
happen to always be at prtad == 0.  This will allow us to set the phy_id
and phy.type correctly now.

- There was timing issue with i2c calls when initiated from a tasklet.
A small delay was added to allow the electrical oscillation to calm down.

- Logic change in ixgbe_sfp_task that allows NOT_SUPPORTED condition
to be recognized.

Peter P Waskiewicz Jr 50ac58ba1d ixgbe: Harden the 82599 multispeed fiber autotry mechanism
82599 supports multispeed fiber optical modules (10Gbps/1Gbps).  Some
scenarios can cause the autotry mechanism to not negotiate link properly.
What needs to happen is the driver must flap the Tx laser to induce an Rx
Loss of Signal on the link partner.  This will restart the autotry
mechanism to get link into a known state.  The software definable pin (SDP)
3 on the 0x10fb NIC is wired to cause a Tx LOS event, which triggers the
Rx LOS we require.

Don Skidmore 8ca783ab78 ixgbe: fix 82598 SFP initialization after driver load.
If we loaded the driver with out a SFP module plugged in it would
leave it in a state that make it later unable to link when a module
was plugged in.  This patch corrects that by:

ixgbe_probe() - moving the check for IXGBE_ERR_SFP_NOT_PRESENT from
after get_invariants() to after reset_hw() as now reset_hw() is
where this condition will be indentified.

ixgbe_reset_hw_82598() - Enable this function to now return
IXGBE_ERR_SFP_NOT_PRESENT.

ixgbe_identify_sfp_module_generic() - This where the lack of SFP
module is detected.  Modifications are added to allow a different
return value for modules that just haven't been plugged in yet.

Other functions were updated to allow correct logging.

Peter P Waskiewicz Jr 537d58a00a ixgbe: Change Direct Attach Twinax cable detection for SFP+ NICs
The SFF specification for Direct Attach cable detection has now been
ratified.  Previously, DA cable detect was looking at the Twinaxial bit in
byte 9 of the SFP+ EEPROM.  The spec now defines active and passive DA
cables in byte 8 of the SFP+ EEPROM.  This patch changes the cable
detection for both 82598 and 82599 SFP+ adapters to conform to the new
spec.

82598 and 82599 do not support SFP 1G modules.  Instead of allowing the
driver to load, but never get link, rejecting the module and displaying
a useful message is more preferrable.  The framework for displaying the
failure message already exists, now we just need to detect and reject the
SFP modules.

PJ Waskiewicz 553b449784 ixgbe: Remove unnecessary PHY reset, properly identify multispeed fiber modules
This patch does two things:
1) On 82599, the PHY is emedded in the MAC.  On 82598, the SFP+ NIC has an external PHY.  The reset in the SFP+ setup patch for 82598 is unnecessary on 82599, and adds extra dead time to device initialization.  This removes that PHY reset for 82599 only.

2) On 82599, the SFP+ modules are multispeed fiber modules (10G/1G).  We need to make sure to identify them properly for the remaining init sections to properly set them up.

Auke Kok 9a799d7103 ixgbe: driver for Intel(R) 82598 PCI-Express 10GbE adapters (v4)
This patch adds support for the Intel 82598 PCI-Express 10GbE
chipset. Devices will be available on the market soon.

This version of the driver is largely the same as the last release:

  * Driver uses a single RX and single TX queue, each using 1 MSI-X
  irq vector.
  * Driver runs in NAPI mode only
  * Driver is largely multiqueue-ready (TM)

Changes since 20070803:
  * removed wrappers for hardware functions
  * incorporated e1000e-style HW api reorganization code
  * sparse/checkpatch cleanups, namespace cleanups
  * driver prints out extra debugging information at load time
    identifying adapter board number, mac, phy types
  * removed ixgbe_api.c, ixgbe_api.h, ixgbe_osdep.h
  * driver update to 1.1.18
  * removed ixgbe.txt which contained no useful info anymore
