Configuring tx_maxrate via sysfs interface
/sys/class/net/eth0/queues/tx-1/tx_maxrate was not working when
TCs are configured because always main VSI was being used. Fix by
using correct VSI in ice_set_tx_maxrate when TCs are configured.

Add meta data matching criteria in the same place as protocol matching
criteria. There is no need to add meta data as special words after
parsing all lookups. Trade meta data in the same why as other lookups.
The one difference between meta data lookups and protocol lookups is
that meta data doesn't impact how the packets looks like. Because of that
ignore it when filling testing packet.
Match on tunnel type meta data always if tunnel type is different than
TNL_LAST.

Information about the direction is currently stored in sw_act.flag.
There is no need to duplicate it in another field.
Setting direction flag doesn't mean that there is a match criteria for
direction in rule. It is only a information for HW from where switch id
should be collected (VSI or port). In current implementation of advance
rule handling, without matching for direction meta data, we can always
set one the same flag and everything will work the same.
Ability to match on direction meta data will be added in follow up
patches.
Recipe 0, 3 and 9 loaded from package has direction match
criteria, but they are handled in other function.
Move ice_adv_rule_info fields to avoid holes.

The > comparison should be >= to prevent reading one element beyond
the end of the array.
The "vsi->num_rxq" is not strictly speaking the number of elements in
the vsi->rxq_map[] array. The array has "vsi->alloc_rxq" elements and
"vsi->num_rxq" is less than or equal to the number of elements in the

an off by one but it might not access outside the end of the array.

Add support for offloading receive filters with action drop
in ADQ/non-ADQ modes. This is in addition to other actions
such as forwarding to a VSI (ADQ) or a queue (ADQ/non-ADQ).

This patch uses TC skbedit queue_mapping action to support
forwarding packets to a device queue. Such filters with action
forward to queue will be the highest priority switch filter in
HW.
Example:
$ tc filter add dev ens4f0 protocol ip ingress flower\
dst_ip 192.168.1.12 ip_proto tcp dst_port 5001\
action skbedit queue_mapping 5 skip_sw
The above command adds an ingress filter, incoming packets
qualifying the match will be accepted into queue 5. The queue
number is in decimal format.
Refactored ice_add_tc_flower_adv_fltr() to consolidate code with
action FWD_TO_VSI and FWD_TO QUEUE.

Commit 34a897758efe ("ice: Add support for inner etype in switchdev")
added the ability to match on inner ethertype. A side effect of that change
is that it is now impossible to add some filters for protocols which do not
contain inner ethtype field. tc requires the protocol field to be specified
when providing certain other options, e.g. src_ip. This is a problem in
case of GTP - when user wants to specify e.g. src_ip, they also need to
specify protocol in tc command (otherwise tc fails with: Illegal "src_ip").
Because GTP is a tunnel, the protocol field is treated as inner protocol.
GTP does not contain inner ethtype field and the filter cannot be added.
To fix this, ignore the ethertype field in case of GTP filters.

TC flower does not support matching on user specified

adds outer destination MAC address as lower netdev's
active unicast MAC address to filter out packets with
unrelated MAC address being delivered to ADQ VSIs.
Example:
- create tunnel device
ip l add $VXLAN_DEV type vxlan id $VXLAN_VNI dstport $VXLAN_PORT \
dev $PF
- add TC filter (in ADQ mode)
$tc filter add dev $VXLAN_DEV protocol ip parent ffff: flower \
dst_ip $INNER_DST_IP ip_proto tcp dst_port $INNER_DST_PORT \

In tunnels packet there can be two UDP headers:
- outer which for hw should be mark as ICE_UDP_OF
- inner which for hw should be mark as ICE_UDP_ILOS or as ICE_TCP_IL if
inner header is of TCP type
In none tunnels packet header can be:
- UDP, which for hw should be mark as ICE_UDP_ILOS
- TCP, which for hw should be mark as ICE_TCP_IL
Change incorrect ICE_UDP_OF for none tunnel packets to ICE_UDP_ILOS.
ICE_UDP_OF is incorrect for none tunnel packets and setting it leads to
error from hw while adding this kind of recipe.
In summary, for tunnel outer port type should always be set to
ICE_UDP_OF, for none tunnel outer and tunnel inner it should always be
set to ICE_UDP_ILOS.

Mostly reuse code from Geneve and VXLAN in TC parsing code. Add new GRE
header to match on correct fields. Create new dummy packets with GRE
fields.
Instead of checking if any encap values are presented in TC flower,
check if device is tunnel type or redirect is to tunnel device. This
will allow adding all combination of rules. For example filters only
with inner fields.
Return error in case device isn't tunnel but encap values are presented.

- from VF to uplink - TC filter is added on PR, for this case check if
redirect device is tunnel device

For now, only supported action is "skip_sw hw_tc <tc_num>"
Filter criteria is specific to channel and it can be
combination of L3, L3+L4, L2+L4.
Example:
MATCH criteria Action
---------------------------
src and/or dest IPv4[6]/mask -> Forward to "hw_tc <tc_num>"
dest IPv4[6]/mask + dest L4 port -> Forward to "hw_tc <tc_num>"
dest MAC + dest L4 port -> Forward to "hw_tc <tc_num>"
src IPv4[6]/mask + src L4 port -> Forward to "hw_tc <tc_num>"
src MAC + src L4 port -> Forward to "hw_tc <tc_num>"
Adding tc-flower filter for channel using "hw_tc"
-------------------------------------------------
tc qdisc add dev <ethX> clsact
Above two steps are only needed the first time when adding
tc-flower filter.
tc filter add dev <ethX> protocol ip ingress prio 1 flower \
dst_ip 192.168.0.1/32 ip_proto tcp dst_port 5001 \
skip_sw hw_tc 1
tc filter show dev <ethX> ingress
filter protocol ip pref 1 flower chain 0
filter protocol ip pref 1 flower chain 0 handle 0x1 hw_tc 1
eth_type ipv4
ip_proto tcp
dst_ip 192.168.0.1
dst_port 5001
skip_sw
in_hw in_hw_count 1
Delete specific filter:
-------------------------
tc filter del dev <ethx> ingress pref 1 handle 0x1 flower
Delete All filters:
------------------

Currently it is not possible to set/unset lb_en and lan_en flags
for advanced rules during their creation. Both flags are enabled
by default. In case of switchdev offloads for egress traffic we
need lb_en to be disabled. Because of that, we work around it by
updating the rule immediately after its creation.
This change allows us to set/unset those flags right away and it
gets rid of old workaround as well. Using ice_adv_rule_flags_info
structure we can pass info about flags we want to be set for
a given advanced rule. Flags are stored in flags_info.act.
Values from act would be used only if act_valid was set to true,
otherwise default values would be used.

Implement ndo_setup_tc net device callback for TC HW offload on PF device.
ndo_setup_tc provides support for HW offloading various TC filters.
Add support for configuring the following filter with tc-flower:
- default L2 filters (src/dst mac addresses, ethertype, VLAN)
- variations of L3, L3+L4, L2+L3+L4 filters using advanced filters
(including ipv4 and ipv6 addresses).
Allow for adding/removing TC flows when PF device is configured in
eswitch switchdev mode. Two types of actions are supported at the
moment: FLOW_ACTION_DROP and FLOW_ACTION_REDIRECT.
