Hardware can support more than 8 queues currently limited by
netif_get_num_default_rss_queues(). So, rework and fix checks for max
number of queues to allocate. The checks should be based on how many are
actually supported by hardware, OR the number of online cpus; whichever
is lower.

T6 can support 2 egress traffic management channels per port to
double the total number of traffic classes that can be configured.
In this configuration, if the class belongs to the other channel,
then all the queues must be bound again explicitly to the new class,
for the rate limit parameters on the other channel to take effect.
So, always explicitly bind all queues to the port rate limit traffic
class, regardless of the traffic management channel that it belongs
to. Also, only bind queues to port rate limit traffic class, if all
the queues don't already belong to an existing different traffic
class.

Currently, the hardware TID index is assumed to start from index 0.
However, with the following changeset,
commit c21939998802 ("cxgb4: add support for high priority filters")
hardware TID index can start after the high priority region, which
has introduced a regression resulting in connection failures for
ULDs.
So, fix all related code to properly recalculate the TID start index
based on whether high priority filters are enabled or not.

Add TC-MATCHALL classifier ingress offload support. The same actions
supported by existing TC-FLOWER offload can be applied to all incoming
traffic on the underlying interface.
Ensure the rule priority doesn't conflict with existing rules in the
TCAM. Only 1 ingress matchall rule can be active at a time on the
underlying interface.
v5:
- No change.
v4:
- Added check to ensure the matchall rule's prio doesn't conflict with
other rules in TCAM.
- Added logic to fill default mask for VIID, if none has been
provided, to prevent conflict with duplicate VIID rules.
- Used existing variables in private structure to fill VIID info,
instead of extracting the info manually.
v3:
- No change.
v2:
- Removed logic to fetch free index from end of TCAM. Must maintain
same ordering as in kernel.

Add TC-MATCHALL classifier offload with TC-POLICE action applied for
all outgoing traffic on the underlying interface. Split flow block
offload to support both egress and ingress classification.
For example, to rate limit all outgoing traffic to 1 Gbps:
$ tc qdisc add dev enp2s0f4 clsact
$ tc filter add dev enp2s0f4 egress matchall skip_sw \
action police rate 1Gbit burst 8Kbit
Note that skip_sw is important. Otherwise, both stack and hardware
will end up doing policing. Policing can't be shared across flow
blocks. Only 1 egress matchall rule can be active at a time on the
underlying interface.
v5:
- No change.
v4:
- Removed check to reject police offload if prio is not 1.
- Moved TC_SETUP_BLOCK code to separate function.
v3:
- Added check to reject police offload if prio is not 1.
- Assign block_shared variable only for TC_SETUP_BLOCK.
v2:
- Added check to reject flow block sharing for policers.

Simplify queue configuration and MSI-X allocation logic. Use a single
MSI-X information table for both NIC and ULDs. Remove hard-coded
MSI-X indices for firmware event queue and non data interrupts.
Instead, use the MSI-X bitmap to obtain a free MSI-X index
dynamically. Save each Rxq's index into the MSI-X information table,
within the Rxq structures themselves, for easier cleanup.

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.
If a debugfs call fails, it will properly warn in the syslog, there's no
need for all individual drivers to also print a message, so that is one
more reason to not care about checking the return values.

Most drivers do the same thing to set up the flow block callbacks, this
patch adds a helper function to do this.
This preparation patch reduces the number of changes to adapt the
existing drivers to use the flow block callback API.
This new helper function takes a flow block list per-driver, which is
set to NULL until this driver list is used.
This patch also introduces the flow_block_command and
flow_block_binder_type enumerations, which are renamed to use
FLOW_BLOCK_* in follow up patches.
There are three definitions (aliases) in order to reduce the number of
updates in this patch, which go away once drivers are fully adapted to
use this flow block API.

same active region resources on the chip with upper layer drivers,
like iw_cxgb4, chcr, etc. Currently, only either Hash filters

use the new firmware configuration parameters (when available)

After the previous patch, all the callers of ndo_select_queue()
provide as a 'fallback' argument netdev_pick_tx.
The only exceptions are nested calls to ndo_select_queue(),
which pass down the 'fallback' available in the current scope
- still netdev_pick_tx.
We can drop such argument and replace fallback() invocation with
netdev_pick_tx(). This avoids an indirect call per xmit packet
in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen)
with device drivers implementing such ndo. It also clean the code
a bit.

TX Queues to get CIDX Updates when:
Time(CIDX == PIDX) >= Timer
Previously we rely on TX Queue Status Page updates by hardware
for DMA completions. This will make Hardware/Firmware actually
deliver the CIDX Updates as Ingress Queue messages with
commensurate Interrupts.
So we now have a new RX Path component for processing CIDX Updates
and reclaiming TX Descriptors faster.

With CONFIG_THERMAL=m, we get a build error:
drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c: In function 'cxgb4_thermal_get_trip_type':
drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c:48:11: error: 'struct adapter' has no member named 'ch_thermal'
Once that is fixed by using IS_ENABLED() checks, we get a link error
against the thermal subsystem when cxgb4 is built-in:
drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_init':
cxgb4_thermal.c:(.text+0x180): undefined reference to `thermal_zone_device_register'
drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_remove':
cxgb4_thermal.c:(.text+0x1e0): undefined reference to `thermal_zone_device_unregister'
Finally, since CONFIG_THERMAL can be =m, the Makefile fails to pick up the
extra file into built-in.a, and we get another link failure against the
cxgb4_thermal_init/cxgb4_thermal_remove files, so the Makefile has to
be adapted as well to work for both CONFIG_THERMAL=y and =m.

After bfcb79fca19d ("PCI/ERR: Run error recovery callbacks for all affected
devices"), AER errors are always cleared by the PCI core and drivers don't
need to do it themselves.
Remove calls to pci_cleanup_aer_uncorrect_error_status() from device
driver error recovery functions.
