Peter P Waskiewicz Jr 1b3ff02eac ixgbe: Properly disable packet split per-ring when globally disabled
The packet split feature was recently moved out of the adapter-wide flags
feature field and into a per-Rx ring feature field.  In the process, packet
split isn't properly disabled in the Rx ring if the adapter has it globally
disabled, followed by a device reset.

This won't impact the driver today, since it's always in packet split mode.
However, this will prevent any pitfalls if someone disables packet split on
the adapter in the future and doesn't disable it in each ring.

Yi Zou 8de8b2e634 ixgbe: Add support for multiple Tx queues for FCoE in 82599
This patch adds support for multiple transmit queues to the Fiber Channel
over Ethernet (FCoE) feature found in 82599. Currently, FCoE has multiple
Rx queues available, along with a redirection table, that helps distribute
the I/O load across multiple CPUs based on the FC exchange ID. To make
this the most effective, we need to provide the same layout of transmit
queues to match receive.

Particularly, when Data Center Bridging (DCB) is enabled, the designated
traffic class for FCoE can have dedicated queues for just FCoE traffic,
while not affecting any other type of traffic flow.

Mallikarjuna R Chilakala c3c7432741 ixgbe: Patch to fix 82599 multispeed fiber link issues when driver is loaded without any cable and reconnecting it to 1G partner
In 82599 multi speed fiber case when driver is loaded without any
cable and reconnecting the cable with a 1G partner does not bring
up the link in 1Gb mode. When there is no link we first setup the link
at 10G & 1G and then try to re-establish the link at highest speed 10G
and thereby changing autoneg_advertised value to highest speed 10G.
After connecting back the cable to a 1G link partner we never try 1G
as autoneg advertised value is changed to link at 10G only. The
following patch fixes the issue by properly initializing the
autoneg_advertised value just before exiting from link setup routine.

Lucy Liu 36e89d73e5 ixgbe: allow vlan egress priority mapping in DCB mode
The skb priority to vlan-qos egress mapping that can be configured using
set_egress_map with vconfig is overriden by the DCB code in the driver.

This patch allows this existing mechanism to work and will increase the
configuration flexibility of DCB mode on Linux.

A hierarchy of configuration is:

1. Modifies the ixgbe_select_queue() routine for DCB mode to return the
priority value from the VLAN tag. It will normally be zero, unless the egress
priority map has modified it. This will get packets into the correct queue and
result in the queue_mapping field being set correctly.

2. Any tc filter which modifies queue_mapping will be honored, as the filters
are handled after the vlan egress map is handled.

Certain types of control packets (LLDP, LACP, etc.) are not supposed to have a
priority tag or vlan tag inserted.  Ixgbe driver is currently priority
tagging everything (if packet is not on a VLAN interface).

This patch modifies DCB mode, so that packets marked with skb priority
TC_PRIO_CONTROL are not priority tagged.  It also transmits these packets on
the highest priority traffic class.
Programs (like dcbd) can set the skb priority using a socket option.  Or, a tc
filter can be configured to set the priority value. Using the value
TC_PRIO_CONTROL (7) has the benefit that it is already defined in the kernel,
and the bonding LACP code already sets the skb->priority field to this value.

Yi Zou 8faa2a786a ixgbe: Fix coexistence of FCoE and Flow Director in 82599
Fix coexistence of Fiber Channel over Ethernet (FCoE) and Flow Director (FDIR)
in 82599 and remove the disabling of FDIR when FCoE is enabled.

Currently, FDIR is turned off when FCoE is enabled under the assumption that
FCoE is always enabled with DCB being turned on. However, FDIR does not have
to be turned off all the time when FCoE is enabled since FCoE can be enabled
without DCB being turned on, e.g., use link pause only. This patch makes sure
that when DCB is turned on or off, FDIR is turned on or off correspondingly;
and when FCoE is enabled, it does not disable FDIR, rather, it will have FDIR
set up properly so FCoE and FDIR can coexist regardless of DCB being on or off.

Don Skidmore 5da43c1a78 ixgbe: fix inconsistent SFP/SFP+ failure results.
Currently if we loaded the driver, insert an unsupported module, and then
attempt to "ifconfig up" the device it will be brought down but the netdev
would not be unregistered. This behavior is different than all other
code paths. This patch corrects that by down'ing the device and then
scheduling the sfp_config_module_task tasklet. The tasklet will detect
this condition (like it does with other code paths) and do the
unregister_netdev().

I also removed the log message as this condition (an unsupported SFP+
module) will be logged in sfp_config_module_task.

Don Skidmore 19343de279 ixgbe: fix regression on some 82598 adapters
The change to check the SFP+ module again on open() was
causing the XFP (non-SFP+) adapters to be rejected. We
only want to try and re-identify the SFP+ module if the
original probe found that this device was an SFP+ device.
So for this code path (driver loaded with SFP module, module
inserted, ifconfig up of the device) the type will be
ixgbe_phy_unknown for an unidentified SFP+ module.  So we
only check if that is the case.

This problem also shows up on Copper devices.

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.

This patch is inspired by patch recently posted by Johannes Berg. Basically what
my patch does is to group list and a count of addresses into newly introduced
structure netdev_hw_addr_list. This brings us two benefits:
1) struct net_device becames a bit nicer.
2) in the future there will be a possibility to operate with lists independently
   on netdevices (with exporting right functions).
I wanted to introduce this patch before I'll post a multicast lists conversion.

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

Peter P Waskiewicz Jr f7c86a3252 ixgbe: Remove device ID 0x10d8
Device ID 0x10d8 is the default silicon device ID for 82599.  However, the
device will not be functional without an EEPROM, so we want to prevent the
driver from loading on the device.  Otherwise, the driver will load, but no
PHY setup or PCIe setup will occur, causing the device to be unusable.  To
prevent users from encountering this, just remove the device ID.

82599 supports using either link flow control or priority flow control when

This patch checks for this failure in:
ixgbe_probe - So we can log the failure asap. We check right after we
set up the adapter->flags, which is when we know that we have a fan.
ixgbe_up_complete - To catch failures that may have happened between probe
and when we set up the interrupt that would normally detect the fan failure.

To enable all of this we need to initialize the adapter flag with
IXGBE_FLAG_FAN_FAIL_CAPABLE when the NIC contained a fan.
