Each interrupt vector has its own bit in the host coalescing register to
force that vector's status block to be updated and generate an

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.

When disabling the Rx and Tx data arbiters prior to configuration changes,
the arbiters were not being shut down properly. This can create a race
in the DCB hardware blocks, and potentially hang the arbiters. Also, the
Tx descriptor arbiter shouldn't be disabled when applying configuration
changes; disabling this arbiter can cause a Tx hang.

Enabling VLAN filters (VFE) when the primary interface is brought up
(per commit 78ed11a) has caused problems for some users who manage
their systems using IPMI over a VLAN. This is because when the driver
enables the VLAN filter, this same filter table is enabled for the
management channel, and the table is initially empty, which means that
the IPMI/VLAN packets are filtered out and not received by the BMC.
This is a problem only on e1000 class adapters, as it is only
on e1000 that the filter table is common to the management and host
streams.
With this change, filtering is only enabled when one or more host VLANs
exist, and is disabled when the last host VLAN is removed. VLAN filtering
is always disabled when the primary interface is in promiscuous mode,
and will be (re)enabled if VLANs exist when the interface exits
promiscuous mode.
Note that this does not completely resolve the issue for those using VLAN
management, because if the host adds a VLAN, then the above problem
occurs when that VLAN is enabled. However, it does mean the there is no
problem for configurations where management is on a VLAN and the host is
not.
A complete solution to this issue would require further driver changes.
The driver would need to discover if (and which) management VLANs are
active before enabling VLAN filtering, so that it could ensure that the
managed VLANs are included in the VLAN filter table. This discovery
requires that the BMC identifies its VLAN in registers accessible
to the driver, and at least on Dell PE2850 systems the BMC does not
identify its VLAN to allow such discovery. Intel is pursuing this issue
with the BMC vendor.

When UMAC stalls or asserts, we want to reset the device. But when we're
associated, the current reset worker will end up calling
cfg80211_connect_result() with the cfg80211 sme layer knowing that we're
reassociating. That ends up with some ugly warnings.
With this patch we're telling the upper layer that we've roamed if
reassociation succeeds, and that we're disconnected if it fails.

The LMAC calibration API got broken mostly by having a configuration bitmap
being different than the result one.
This patch tries to address that issue by correctly running calibrations with
the newest firmwares, and keeping a backward compatibility fallback path for
older firmwares, where the configuration and result bitmaps were identical.

When the driver receives "connection terminated" event from device,
it could be caused by 2 reasons: the firmware is roaming or the
connection is lost (AP disappears). For the former, an association
complete event is supposed to come within 3 seconds. For the latter,
the driver won't receive any event except the connection terminated.
So we kick a delayed work (5*HZ) when we receive the connection
terminated event. It will be canceled if it turns out to be a roaming
event later. Otherwise we notify SME and userspace the disconnection.

consequently allows us to dynamically turn FCoE offload feature on or off
