We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
meet kernel coding style guidelines. This issue was reported by checkpatch.
A simplified version of the semantic patch that makes this change is as
follows (http://coccinelle.lip6.fr/):
// <smpl>
@@
identifier i;
declarer name DEFINE_PCI_DEVICE_TABLE;
initializer z;
@@
- DEFINE_PCI_DEVICE_TABLE(i)

= z;

Old versions of BE3 FW may not support cmds to re-provision (and hence
optimize) resources/queues in SR-IOV config. Do not treat this FW cmd
failure as fatal and fail the function initialization. Instead, just
enable SR-IOV with the resources provided by the FW.
Prior to the "create optimal number of queues on SR-IOV config" patch
such failures were ignored.

In the shutdown path, when be2net calls pci_disable_msix(), it
complains (BUG_ON) that irqs requested by ocrdma driver are still in
use. This patch fixes this problem by issuing shutdown event to
ocrdma from be2net shutdown path. As part of shutdown event
processing, ocrdma driver will free up all the resources and free
irqs. Once this completes be2net completes pci_disable_msix
successfully.

The driver so far used adapter->num_vfs value to check if SR-IOV is enabled
or not. But, the patch bec84e6("create optimal number of queues on SR-IOV
config") changed this logic. The adapter->num_vfs value is validated and set
much before SR-IOV is enabled. So, we now use an explicit flag to track
SR-IOV enabled state.

A pointer to adapter struct is passed anyway to all of the FW-cmd routines
in be_cmds.c. For routines which query data from FW, the adapter pointer
is enough to return the queried fields.
There is no need to separately pass pointers to individual members of
the adapter structure. This patch fixes this for be_cmd_get_fw_ver()
and be_cmd_get_fw_cfg() routines.

If SR-IOV is enabled in the adapter, the FW distributes queue resources
evenly across the PF and it's VFs. If the user is not interested in enabling
VFs, the queues set aside for VFs are wasted.
This patch adds support for the PF driver to re-configure the resource
distribution in FW based on the number of VFs enabled by the user.
This also allows for supporting RSS queues on VFs, when less number of VFs
are enabled per PF. When maximum number of VFs are enabled, each VF typically
gets only one RXQ.

The driver (on PF or VF) needs to detect if the function is in qnq mode for
a HW hack in be_rx_compl_get() to work.
The driver queries this information using the GET_PROFILE_CONFIG cmd
(since the commit below can caused this regression.) But this cmd is not
available on VFs and so the VFs fail to detect qnq mode. This causes
vlan traffic to not work.
The fix is to use the the adapter->function_mode value queried via
QUERY_FIRMWARE_CONFIG cmd on both PFs and VFs to detect the qnq mode.
Also QNQ_MODE was incorrectly named FLEX10_MODE; correcting that too as the
fix reads much better with the name change.

This patch improves MCCQ error status handling in the following ways:
a) A MCC cmd completion returns a base-status and an addl-status.
So far, the routine be_mcc_compl_process() returned only the "status" value.
Now, embedd both statuses in the return value and let the caller routine access
the value of interest using base_status() and addl_status() macros.
b) Rename variables accordingly (base/addl) to avoid confusion while error
checking.
b) Some of the errors returned by FW are harmless and so an error msg is not
logged for such errors. Capture this logic in a separate routine to make the
code more readable.

Certain new flash regions have been added to Skyhawk-R FW image. The newer
FW images specify op_types for each region. A region is flashed only
when it's CRC doesn't match that of the region on the HW flash. While
upgrading to a new FW image the driver is expected to tolerate certain
errors.

speed, set via the SET_PROFILE_CONFIG cmd.
This patch makes the necessary changes to the FW cmd descriptors to support

only discrete values (that map to % of the link-speed).

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: -

In the EEH error recovery path, when a permanent failure occurs,
we clean up adapter structure (i.e. destroy queues etc) by calling
be_clear() and return PCI_ERS_RESULT_DISCONNECT.
After this the stack tries to remove device from bus and calls
be_remove() which invokes netdev_unregister()->be_close().
be_close() operating on destroyed queues results in a
NULL dereference.
This patch fixes this problem by introducing a flag to keep track
of the setup state.

be_close() currently waits for a max of 200ms to receive all pending
TX compls. This timeout value was roughly calculated based on 10G
transmission speeds and the TX queue depth. This timeout may not be
enough when the link is operating at lower speeds or in multi-channel/SR-IOV
configs with TX-rate limiting setting.
It is hard to calculate a "proper timeout value" that works in all
configurations. This patch solves this problem by continuing to reap
TX completions till the HW is completely silent for a period of 10ms or
a HW error is detected.
v2: implements the new scheme (as suggested by David Laight) instead of
just waiting longer than 200ms for reaping all completions.

This patch re-factors the be_set_profile_config() code (used so far
only for setting VF QoS) to be used to set any type of descriptor.
2) The MANAGE_IFACE_FILTERS cmds is needed to convert a normal interface
into a tunnel interface. This allows for RSS to work even on the inner
TCP/UDP headers of VxLAN traffic.

Use GET_PROFILE_CONFIG_V1 cmd even for BE3-R (it's already used for
Lancer-R and Skyhawk-R), to query max-vfs value supported by the FW.
This is needed as on some configs, the value exported in the PCI-config
space is not accurate.

Conflicts:
drivers/net/wireless/ath/ath9k/recv.c
drivers/net/wireless/mwifiex/pcie.c
net/ipv6/sit.c
The SIT driver conflict consists of a bug fix being done by hand
in 'net' (missing u64_stats_init()) whilst in 'net-next' a helper
was created (netdev_alloc_pcpu_stats()) which takes care of this.
The two wireless conflicts were overlapping changes.

The driver currently maps a page for DMA, divides the page into multiple
frags and posts them to the HW. It un-maps the page after data is received
on all the frags of the page. This scheme doesn't work when bounce buffers
are used for DMA (swiotlb=force kernel param).
This patch fixes this problem by calling dma_sync_single_for_cpu() for each
frag (excepting the last one) so that the data is copied from the bounce
buffers. The page is un-mapped only when DMA finishes on the last frag of
the page.
(Thanks Ben H. for suggesting the dma_sync API!)
This patch also renames the "last_page_user" field of be_rx_page_info{}
struct to "last_frag" to improve readability of the fixed code.

Some of TX workarounds in be_xmit_workarounds() routine
are not applicable (and result in HW errors) to Skyhawk-R chip.
Isolate BE3-R/Lancer specific workarounds to a separate routine.

skb_padto(), skb_share_check() and __vlan_put_tag() routines free
skb when they return an error. This patch fixes be_xmit_workarounds()
to not free skb again in such cases.

We should clear promiscuous bits in adapter->flags while disabling promiscuous
mode. Else we will not put interface back into VLAN promisc mode if the vlans
already added exceeds the maximum limit.
