Add code to query and set the number of channels on the primary VSI for a
PF. This is accessed from the 'ethtool -l' and 'ethtool -L' commands,
respectively. Though the ice driver supports asymmetric queues report an
IRQ vector that has both Rx and Tx queues attached and is counted as a
'combined' channel.

When code reaches the "out" label, n is guaranteed to be valid so we can
unconditionally call neigh_release.
Also change the label to release_neigh to better reflect the fact that
we unconditionally free the neighbour and also match other labels

Improve mlx5e_route_lookup_ipv6 function structure by avoiding #ifdef then
return -EOPNOTSUPP in the middle of the function code.
To do so, we stub out mlx5e_tc_tun_create_header_ipv6 which is the only
caller of this helper function to avoid calling it altogether
when ipv6 is compiled out, which should also cleanup some compiler
warnings of unused variables.

Refactor flex parser tunnel code:
- Add definition for flex parser tunneling header for VXLAN-GPE
- Use macros for VXLAN-GPE SW steering when building STE
- Refactor the code to reflect that this is a VXLAN GPE
only code and not a general flex parser code.
This also significantly simplifies addition of more
flex parser protocols, such as Geneve.

The virtchannel interface was repeating a lot of strings
and wasting storage space in the kernel. There was also

Currently ice_clear_vsi_promisc() detects if the VLAN ID sent is not 0
and sets the recipe_id to ICE_SW_LKUP_PROMISC_VLAN in that case and
ICE_SW_LKUP_PROMISC if the VLAN_ID is 0. However this doesn't allow VLAN
0 promiscuous rules to be removed, but they can be added. Fix this by
checking if the promisc_mask contains ICE_PROMISC_VLAN_RX or
ICE_PROMISC_VLAN_TX. This change was made to match what is being done
for ice_set_vsi_promisc().

It is wrong to set PF disable state flag for all VFs when freeing VF
resources - Instead, we should set VF disable state flag for each VF with
its resources being returned to the device. Right now, all VF opcodes,
mailbox communication to clear its resources as well fails - since we
already indicate that PF is in disable state, with all VFs not active. In
addition, we don't need to notify VF that PF is intending to reset it, if
it is already in disabled state.

Currently when adding/deleting vlans in ice_vc_process_vlan_msg()
we are calling ice_vsi_manage_vlan_stripping() to enable/disable
when adding and deleting a VLAN respectively. This is wrong
because adding/deleting VLANs has nothing to do with configuring
VLAN stripping. VLAN stripping is configured through the
following VIRTCHNL operations:
VIRTCHNL_OP_ENABLE_VLAN_STRIPPING
VIRTCHNL_OP_DISABLE_VLAN_STRIPPING
Unfortunately we can't just remove this because then stripping
will never be configured on VF initialization. Fix this by
adding a new function that initializes (disables/enables) VLAN
stripping for the VF based on the device supported capabilities.
This allows us to remove the call to
ice_vsi_manage_vlan_stripping() in ice_vc_process_vlan_msg().

Currently if the host disables VLAN offloads on the VF by
not setting the VIRTCHNL_VF_OFFLOAD_VLAN capability bit
we will still honor VF VLAN configuration messages over
VIRTCHNL. These messages (i.e. enable/disable VLAN stripping
and VLAN filtering) should be blocked when the feature
is not supported. Fix that by adding a helper function to
determine if the VF is allowed to do VLAN operations based
on the host's VF configuration.
Also, mirror the VF communicated capabilities in the host's
VF configuration.

The main changes are:
1) Addition of BPF trampoline which works as a bridge between kernel functions,
BPF programs and other BPF programs along with two new use cases: i) fentry/fexit
BPF programs for tracing with practically zero overhead to call into BPF (as
opposed to k[ret]probes) and ii) attachment of the former to networking related
programs to see input/output of networking programs (covering xdpdump use case),
from Alexei Starovoitov.
2) BPF array map mmap support and use in libbpf for global data maps; also a big
batch of libbpf improvements, among others, support for reading bitfields in a
relocatable manner (via libbpf's CO-RE helper API), from Andrii Nakryiko.
3) Extend s390x JIT with usage of relative long jumps and loads in order to lift

4) Add BPF audit support and emit messages upon successful prog load and unload in
order to have a timeline of events, from Daniel Borkmann and Jiri Olsa.
5) Extension to libbpf and xdpsock sample programs to demo the shared umem mode
(XDP_SHARED_UMEM) as well as RX-only and TX-only sockets, from Magnus Karlsson.

When receiving many or larger packets, e.g. when doing a file download,
it was observed that the read buffer size register reports up to 4 bytes
more than the current define allows in the check.
If this is the case, then no data transfer is initiated to receive the
packets (and thus to empty the buffer) which results in a stall of the
interface.
These 4 bytes are a hardware generated frame length which is prepended
to the actual frame, thus we have to respect it during our check.

On some old Firmwares, connector type value was not supported, and value
read from FW was 0. For those, driver used link mode in order to set
connector type in link_ksetting.
After FW exposed the connector type, driver translated the value to ethtool
definitions. However, as 0 is a valid value, before returning PORT_OTHER,
driver run the check of link mode in order to maintain backward
compatibility.
Cited patch added support to EXT mode. With both features (connector type
and EXT link modes) ,if connector_type read from FW is 0 and EXT mode is
set, driver mistakenly compare EXT link modes to non-EXT link mode.
Fixed that by skipping this comparison if we are in EXT mode, as connector
type value is valid in this scenario.

Mirred action parsing code in parse_tc_fdb_actions() first checks if
out_dev has same parent id, and only verifies that there is a pending encap
action that was parsed before. Recent change in vxlan module made function
netdev_port_same_parent_id() to return true when called for mlx5 eswitch
representor and vxlan device created explicitly on mlx5 representor
device (vxlan devices created with "external" flag without explicitly
specifying parent interface are not affected). With call to
netdev_port_same_parent_id() returning true, incorrect code path is chosen
and encap rules fail to offload because vxlan dev is not a valid eswitch
forwarding dev. Dmesg log of error:
[ 1784.389797] devices ens1f0_0 vxlan1 not on same switch HW, can't offload forwarding
In order to fix the issue, rearrange conditional in parse_tc_fdb_actions()
to check for pending encap action before checking if out_dev has the same
parent id.

Current code uses the old method of prio encoding in
flow_cls_common_offload. Fix to follow the changes introduced in
commit ef01adae0e43 ("net: sched: use major priority number as hardware priority").

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.
