This driver currently doesn't support any control flags.
Use flow_rule_match_has_control_flags() to check for control flags,
such as can be set through `tc flower ... ip_flags frag`.
In case any control flags are masked, flow_rule_match_has_control_flags()
sets a NL extended error message, and we return -EOPNOTSUPP.
Only compile-tested.
Only compile tested, no hardware available.

The flower_stats_timer can schedule flower_stats_work and
flower_stats_work can also arm the flower_stats_timer. The
process is shown below:
----------- timer schedules work ------------
ch_flower_stats_cb() //timer handler
schedule_work(&adap->flower_stats_work);
----------- work arms timer ------------
ch_flower_stats_handler() //workqueue callback function
mod_timer(&adap->flower_stats_timer, ...);
When the cxgb4 device is detaching, the timer and workqueue
could still be rearmed. The process is shown below:
(cleanup routine) | (timer and workqueue routine)
remove_one() |
free_some_resources() | ch_flower_stats_cb() //timer
cxgb4_cleanup_tc_flower() | schedule_work()
del_timer_sync() |
| ch_flower_stats_handler() //workqueue
| mod_timer()
cancel_work_sync() |
kfree(adapter) //FREE | ch_flower_stats_cb() //timer
| adap->flower_stats_work //USE
This patch changes del_timer_sync() to timer_shutdown_sync(),
which could prevent rearming of the timer from the workqueue.

commit db43b30cd89c ("cxgb4: add ethtool n-tuple filter deletion")
has moved searching for next highest priority HASH filter rule to
cxgb4_flow_rule_destroy(), which searches the rhashtable before the
the rule is removed from it and hence always finds at least 1 entry.
Fix by removing the rule from rhashtable first before calling
cxgb4_flow_rule_destroy() and hence avoid fetching stale info.

The 4-tuple NAT offload via PEDIT always overwrites all the 4-tuple
fields even if they had not been explicitly enabled. If any fields in
the 4-tuple are not enabled, then the hardware overwrites the
disabled fields with zeros, instead of ignoring them.
So, add a parser that can translate the enabled 4-tuple PEDIT fields
to one of the NAT mode combinations supported by the hardware and
hence avoid overwriting disabled fields to 0. Any rule with
unsupported NAT mode combination is rejected.

commit c8729cac2a11 ("cxgb4: add ethtool n-tuple filter insertion")
has removed checking control key for determining IP address types
for TC-FLOWER rules, which causes all the rules being inserted to
hardware to become IPv6 rule type always. So, add back the check
to select the correct IP address type to extract and hence fix the
correct rule type being inserted to hardware.
Also, ethtool_rx_flow_key doesn't have any control key and instead
directly sets the IPv4/IPv6 address keys. So, explicitly set the
IP address type for ethtool n-tuple filters to reuse the same code.

Add mirror Virtual Interface (VI) support to receive all ingress
mirror traffic from the underlying device. The mirror VI is
created dynamically, if the TC-MATCHALL rule has a corresponding
mirror action. Also request MSI-X vectors needed for the mirror VI
Rxqs. If no vectors are available, then disable mirror VI support.
v3:
- Replace mirror VI refcount_t with normal u32 variable.
v2:
- Add mutex to protect all mirror VI data, instead of just
mirror Rxqs.

Chelsio NICs have 3 filter regions, in following order of priority:
1. High Priority (HPFILTER) region (Highest Priority).
2. HASH region.
3. Normal FILTER region (Lowest Priority).
Currently, there's a 1-to-1 mapping between the prio value passed
by TC and the filter region index. However, it's possible to have
multiple TC rules with the same prio value. In this case, if a region
is exhausted, no attempt is made to try inserting the rule in the
next available region.
So, rework and remove the 1-to-1 mapping. Instead, dynamically select
the region to insert the filter rule, as long as the new rule's prio
value doesn't conflict with existing rules across all the 3 regions.

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.

Only offload rule if it satisfies both of the following conditions:
1. The immediate previous rule has priority <= current rule's priority.
2. The immediate next rule has priority >= current rule's priority.
Also rework free entry fetch logic to search from end of TCAM, instead
of beginning, because higher indices have lower priority than lower
indices. This is similar to how TC auto generates priority values.
v5:
- Fixed commit message and comment to include comparison for equal
priority.
v4:
- Patch added in this version.

This patch wraps the dissector key and mask - that flower uses to
represent the matching side - around the flow_match structure.
To avoid a follow up patch that would edit the same LoCs in the drivers,
this patch also wraps this new flow match structure around the flow rule
object. This new structure will also contain the flow actions in follow
up patches.
This introduces two new interfaces:
bool flow_rule_match_key(rule, dissector_id)
that returns true if a given matching key is set on, and:
flow_rule_match_XYZ(rule, &match);
To fetch the matching side XYZ into the match container structure, to
retrieve the key and the mask with one single call.

Most callers of rhashtable_walk_start don't care about a resize event
which is indicated by a return value of -EAGAIN. So calls to
rhashtable_walk_start are wrapped wih code to ignore -EAGAIN. Something
like this is common:
ret = rhashtable_walk_start(rhiter);
if (ret && ret != -EAGAIN)
goto out;
Since zero and -EAGAIN are the only possible return values from the
function this check is pointless. The condition never evaluates to true.
This patch changes rhashtable_walk_start to return void. This simplifies
code for the callers that ignore -EAGAIN. For the few cases where the
caller cares about the resize event, particularly where the table can be
walked in mulitple parts for netlink or seq file dump, the function
rhashtable_walk_start_check has been added that returns -EAGAIN on a
resize event.
