qlcnic driver uses u16 to store SPEED_UKNOWN ethtool constant,
which is defined as -1, resulting in value truncation and
thus incorrect test results against SPEED_UNKNOWN.
For example, the following test will print "False":
u16 speed = SPEED_UNKNOWN;
if (speed == SPEED_UNKNOWN)
printf("True");
else
printf("False");
Change storage of speed to use u32 to avoid this issue.

In regular NIC transmission flow, driver always configures MAC using
Tx queue zero descriptor as a part of MAC learning flow.
But with multi Tx queue supported NIC, regular transmission can occur on
any non-zero Tx queue and from that context it uses
Tx queue zero descriptor to configure MAC, at the same time TX queue
zero could be used by another CPU for regular transmission
which could lead to Tx queue zero descriptor corruption and cause FW
abort.
This patch fixes this in such a way that driver always configures
learned MAC address from the same Tx queue which is used for
regular transmission.

Qlogic's 82xx series adapter doesn't support
tunnel offloads, driver incorrectly assumes that it is
supported and causes firmware hang while running tunnel IO.
This patch fixes this by not advertising tunnel offloads
for 82xx adapters.

This change replaces the network device operations for adding or removing a
VXLAN port with operations that are more generically defined to be used for
any UDP offload port but provide a type. As such by just adding a line to
verify that the offload type is VXLAN we can maintain the same
functionality.

o While the driver is in the middle of a MB completion processing
and it receives a spurious MB interrupt, it is mistaken as a good MB
completion interrupt leading to premature completion of the next MB
request. Fix the driver to guard against this by checking the current
state of MB processing and ignore the spurious interrupt.
Also added a stats counter to record this condition.

The only instance of a qlcnic_mbx_ops structure is never modified. Thus
the declaration of the structure and all references to the structure type
can be made const.
In the definition of the qlcnic_mailbox structure, the ops field is no
longer lined up with the other fields. This was left as is, to avoid a lot
of trivial changes on the other lines.
Done with the help of Coccinelle.

In some cases it is required to capture minidump for iSCSI functions
as part of default minidump collection process. To enable this, firmware
exports it's capability and driver need to enable that capability
by issuing a mailbox command.
With this feature, firmware can provide additional iSCSI function's
minidump with smaller minidump capture mask (0x1f).

Replace confusing QL_STATUS_INVALID_PARAM == -1 == -EPERM with -EINVAL
and QLC_STATUS_UNSUPPORTED_CMD == -2 == -ENOENT with -EOPNOTSUPP, the
latter error code is arguable, but it is already used in the driver,
so let it be here as well.
Also remove always false (!buf) check on read(), the driver should
not care if userspace gets its EFAULT or not.

Driver keeps adding multicast addresses without deleting removed MACs and
worrying about adapters filter limit. This results into actual count of programmed
multicast addresses get accumulated over the time and overruns the adapter's
filter limit without putting device in ACCEPT_ALL_MULTI mode. This causes
newly added multicast traffic to fail after the sequence of addition - deletion
in certain pattern.
This issue is seen only when netdev's mcast list count is less than adapters
mcast filter limit.
e.g. If adapters multicast filter limit is 38 per function
then following sequence would result in multicast traffic failure for
newly added MACs.
- add less than 38 multicast MACs
- remove previously added multicast MACs
- add new multicast MACs (less than 38)

This patch adds support to run Power On Self Test (POST) for 83xx adapters.
POST can be run in 3 different speed modes :
i) Fast mode (takes about 690 ms)
ii) Medium mode (takes about 2930 ms)
iii) Slow mode (takes about 7500 ms)
To run POST, firmware file with name "83xx_post_fw.bin" should be present under
/lib/firmware directory. load_fw_file module parameter is used to specify
POST operation and its speed mode.
load_fw_file = 2 : Fast mode
load_fw_file = 3 : Medium mode
load_fw_file = 4 : Slow mode

through ip tool.
o min_tx_rate puts lower limit on the VF bandwidth. VF is guaranteed
to have a bandwidth of at least this value.
max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth
of up to this value.
o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced
which takes 4 arguments:
netdev, VF number, min_tx_rate, max_tx_rate
o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler.
o Drivers that currently implement ndo_set_vf_tx_rate should now call
ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth
greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet
implemented by driver.
o If user enters only one of either min_tx_rate or max_tx_rate, then,
userland should read back the other value from driver and set both
for IFLA_VF_RATE.
Drivers that have not yet implemented IFLA_VF_RATE should always
return min_tx_rate as 0 when read from ip tool.
o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then
IFLA_VF_RATE should override.
o Idea is to have consistent display of rate values to user.
o Usage example: -

Conflicts:
drivers/net/ethernet/altera/altera_sgdma.c
net/netlink/af_netlink.c
net/sched/cls_api.c
net/sched/sch_api.c
The netlink conflict dealt with moving to netlink_capable() and
netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations
in non-init namespaces. These were simple transformations from
netlink_capable to netlink_ns_capable.
The Altera driver conflict was simply code removal overlapping some
void pointer cast cleanups in net-next.
