This patch adds support for processing the port misconfigure async
event generated by the FW. This event is generated typically when an
optical module is incorrectly installed or is faulty.
This patch also moves the port_name field to the adapter struct for
logging the event. As the be_cmd_query_port_name() call is now moved
to be_get_config(), it is modified to use the mailbox instead of MCCQ

This patch passes BE_IF_FLAGS_XXX flags to be_cmd_rx_filter() routine

also removes code for setting if_flags_mask that was duplicated for each

While sending FW update cmds to the FW, the driver specifies the "type"
of each component that needs to be flashed. The FW then picks the offset
in the flash area at which the componnet is to be flashed. This doesn't work
when new components that the current FW doesn't recognize, need to be
flashed. Recent FWs (10.2 and above) support a scheme of FW-update wherein
the "offset" of the component in the flash area can be specified instead
of the "type". This patch uses the "offset" based FW-update mechanism and
only when it fails, it fallsback to the old "type" based update.

This patch uses skb->xmit_more flag to batch TX requests.
TX is flushed either when xmit_more is false or there is
no more space in the TXQ.
Skyhawk-R and BEx chips require an even number of wrbs to be posted.
So, when a batch of TX requests is accumulated, the last header wrb
may need to be fixed with an extra dummy wrb.
This patch refactors be_xmit() routine as a sequence of be_xmit_enqueue()
and be_xmit_flush() calls. The Tx completion code is also
updated to be able to unmap/free a batch of skbs rather than a single
skb.

GSO isn't the only offload feature with restrictions that
potentially can't be expressed with the current features mechanism.
Checksum is another although it's a general issue that could in
theory apply to anything. Even if it may be possible to
implement these restrictions in other ways, it can result in
duplicate code or inefficient per-packet behavior.
This generalizes ndo_gso_check so that drivers can remove any
features that don't make sense for a given packet, similar to
netif_skb_features(). It also converts existing driver
restrictions to the new format, completing the work that was
done to support tunnel protocols since the issues apply to
checksums as well.
By actually removing features from the set that are used to do
offloading, it solves another problem with the existing
interface. In these cases, GSO would run with the original set
of features and not do anything because it appears that
segmentation is not required.

The encapsulated offload flags shouldn't be unconditionally exported
to the stack. The stack expects offloading to work across all tunnel
types when those flags are set. This would break other tunnels (like
GRE) since be2net currently supports tunnel offload for VxLAN only.
Also, with VxLANs Skyhawk-R can offload only 1 UDP dport. If more
than 1 UDP port is added, we should disable offloads in that case too.

This patch extends the set/get_rxfh ethtool-options for getting or
setting the RSS hash function.
It modifies drivers implementation of set/get_rxfh accordingly.
This change also delegates the responsibility of checking whether a
modification to a certain RX flow hash parameter is supported to the
driver implementation of set_rxfh.
User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.
Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.

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.

Pull request: Fixes for new ethtool RSS commands
This addresses several problems I previously identified with the new
ETHTOOL_{G,S}RSSH commands:
1. Missing validation of reserved parameters
2. Vague documentation
3. Use of unnamed magic number
4. No consolidation with existing driver operations
I don't currently have access to suitable network hardware, but have
tested these changes with a dummy driver that can support various
combinations of operations and sizes, together with (a) Debian's ethtool
3.13 (b) ethtool 3.14 with the submitted patch to use ETHTOOL_{G,S}RSSH

The MCC async event processing code has 2 issues:
a) because of long struct names the code indentation is badly broken
b) description and definitions of how an MCC completion is interpreted as
an async event are confusing (for e.g. the last word of an MCC event is
named "code", while "code" is just a sub-field of the last word.)
This patch fixes the structure definitions, comments and re-factors code
as needed.

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.
