Traffic received with a priority tag (VID = 0) and non-zero priority value was
incorrectly handled by the VLAN packet code path due to a check on zero for
the whole VLAN tag instead of just the VID.
This patch masked out the priority field when checking the vlan tag for
received VLAN packets.

We return the ddp->len in ixgbe_fcoe_ddp() to indicate the length of data that
have been DDPed. However, it is possible that the length is 0, e.g., for SCSI
READ, the FCP_RSP may come back w/ SCSI status 0x28 as Task Set Full with no FCP
data for DDP. In ixgbe_fcoe_ddp(), we return 0 to indicate not passing DDPed
packets to upper layer. Therefore in the case of ddp->len being 0 upon FCP_RSP,
we do not want to return the 0 ddp->len as we want FCP_RSP to be always
delivered to the upper layer. This patch fixes this bug by setting rc only if
ddp->len is non-zero.

Currently setting rx-usecs when the interface is in legacy interrupt
mode it is not immediate. We were only setting EITR for each MSIx
vector and since this count would be zero for legacy mode it wasn't
set until after a reset. This patch corrects that by checking what
mode we are in and then setting EITR accordingly.

For 82599, packet split has to be disabled for FCoE direct data placement.
However, this is only required on received queues allocated for FCoE. This
patch adds a per ring flags to indicate if packet split is disabled on a
per queue basis, particularly for FCoE, as packet split must be disabled
for large receive using direct data placement (DDP).

Instead of passing the register index of the corresponding rx_ring and find
the way back to get to corresponding rx_ring in ixgbe_configure_srrctl(),
simplify the function ixgbe_configure_srrctl() by passing the rx_ring into
it. Then the register index for that rx_ring is already available from
rx_ring->reg_idx.

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.

The default completion timeout values for 82598 should be in the
range of 50us to 50ms, however the hardware default for these
parts is 500us to 1ms which is less than the 10ms recommended by
the pcie spec. To address this we need to increase the value to
either 10ms to 250ms for capability version 1 configuration, or
16ms to 55ms for version 2.

When a user disables interrupt throttling with ethtool on 82599 devices,
the interrupt timer may not be re-enabled if hardware RSC is running. The
RSC completions in hardware don't complete before the next ITR event tries
to fire, so the ITR timer never gets re-armed. This patch increases the
amount of time between interrupts when throttling is disabled (rx-usecs =
0) when the hardware RSC deature is enabled.

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.

Currently, FCoE offload feature is turned on when the kernel config has
CONFIG_FCOE or CONFIG_FCOE_MODULE set. However, we really want to turn
FCoE offload on when there is FCoE traffic passing and turn it off when
it's just LAN traffic. Since FCoE depends on a lossless network provided
by DCB, this allows us to have FCoE turned on/off when user turns on DCB
using dcbtool.

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.

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.

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.

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.

skb_dma_unmap() is quite expensive for small packets,
because we use two different cache lines from skb_shared_info.
One to access nr_frags, one to access dma_maps[0]
Instead of dma_maps being an array of MAX_SKB_FRAGS + 1 elements,
let dma_head alone in a new dma_head field, close to nr_frags,
to reduce cache lines misses.
