XDP queues are created/destroyed when a XDP program
is attached/detached. In current driver xdp_queues are not
getting destroyed on program exit due to incorrect xdp_queue
and tot_tx_queue count values.
This patch fixes the issue by setting tot_tx_queue and xdp_queue
count to correct values. It also fixes xdp.data_hard_start address.

Add the RSS context parameters to struct ethtool_rxfh_param and use the
get/set_rxfh to handle the RSS contexts as well.
This is part 2/2 of the fix suggested in [1]:
- Add a rss_context member to the argument struct and a capability
like cap_link_lanes_supported to indicate whether driver supports
rss contexts, then you can remove *et_rxfh_context functions,
and instead call *et_rxfh() with a non-zero rss_context.

The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters
as direct function arguments. This will force us to change the API (and
all drivers' functions) every time some new parameters are added.
This is part 1/2 of the fix, as suggested in [1]:
- First simplify the code by always providing a pointer to all params
(indir, key and func); the fact that some of them may be NULL seems
like a weird historic thing or a premature optimization.
It will simplify the drivers if all pointers are always present.
- Then make the functions take a dev pointer, and a pointer to a
single struct wrapping all arguments. The set_* should also take
an extack.

As of today, hardware does not support installing tc filter

Add support for ptp 1-step mode using timecounter. The seconds and
nanoseconds to be updated in PTP header are calculated by adding the
timecounter offset to the free running PTP clock counter time. The PF
driver periodically gets the PTP clock time using AF mbox. The 1-step
support uses HW feature to update correction field rather than
OriginTimestamp field in PTP header.

In the existing code while changing the number of TX/RX
queues using ethtool the PF/VF interface resources are
freed and reallocated (otx2_stop and otx2_open is called)
if the device is in running state. If any resource allocation
fails in otx2_open, driver free already allocated resources
and return. But again, when the number of queues changes
as the device state still running oxt2_stop is called.
In which we try to free already freed resources leading
to driver crash.
This patch fixes the issue by setting the INTF_DOWN flag on
error and free the resources in otx2_stop only if the flag is
not set.

Code at line 967 implies that rsp->fwdata.supported_fec may be up to 4:
967: if (rsp->fwdata.supported_fec <= FEC_MAX_INDEX)
If rsp->fwdata.supported_fec evaluates to 4, then there is an
out-of-bounds read at line 971 because fec is an array with
a maximum of 4 elements:
954 const int fec[] = {
955 ETHTOOL_FEC_OFF,
956 ETHTOOL_FEC_BASER,
957 ETHTOOL_FEC_RS,
958 ETHTOOL_FEC_BASER | ETHTOOL_FEC_RS};
959 #define FEC_MAX_INDEX 4
971: fecparam->fec = fec[rsp->fwdata.supported_fec];
Fix this by properly indexing fec[] with rsp->fwdata.supported_fec - 1.
In this case the proper indexes 0 to 3 are used when
rsp->fwdata.supported_fec evaluates to a range of 1 to 4, correspondingly.

Support SPI and sequence number fields of
ESP/AH header to be hashed for RSS. By default
ESP/AH fields are not considered for RSS and
needs to be set explicitly as below:
ethtool -U eth0 rx-flow-hash esp4 sdfn
or
ethtool -U eth0 rx-flow-hash ah4 sdfn
or
ethtool -U eth0 rx-flow-hash esp6 sdfn
or
ethtool -U eth0 rx-flow-hash ah6 sdfn
To disable hashing of ESP fields:
ethtool -U eth0 rx-flow-hash esp4 sd
or
ethtool -U eth0 rx-flow-hash ah4 sd
or
ethtool -U eth0 rx-flow-hash esp6 sd
or
ethtool -U eth0 rx-flow-hash ah6 sd

Hardware supports 8 RSS groups per interface. Currently we are using
only group '0'. This patch allows user to create new RSS groups/contexts
and use the same as destination for flow steering rules.
usage:
To steer the traffic to RQ 2,3
ethtool -X eth0 weight 0 0 1 1 context new
(It will print the allocated context id number)
New RSS context is 1
ethtool -N eth0 flow-type tcp4 dst-port 80 context 1 loc 1
To delete the context
ethtool -X eth0 context 1 delete
When an RSS context is removed, the active classification
rules using this context are also removed.
Change-log:
v4
- Fixed compiletime warning.
- Address Saeed's comments on v3.
v3
- Coverted otx2_set_rxfh() to use new function.
v2
- Removed unrelated whitespace
- Coverted otx2_get_rxfh() to use new function.

This patch adds support for adding and deleting ethtool ntuple
filters. The filters for ether, ipv4, ipv6, tcp, udp and sctp
are supported. The mask is also supported. The supported actions
are drop and direct to a queue. Additionally we support FLOW_EXT
field vlan_tci and FLOW_MAC_EXT.
The NIX PF will allocate total 32 MCAM entries for the use of
ethtool ntuple filters. The Administrative Function(AF) will
install/delete the MCAM rules when NIX PF sends mailbox message
to install/delete the ntuple filters.
Ethtool ntuple filters support is restricted to PFs as of now
and PF can install ntuple filters to direct the traffic to its
VFs. Hence added a separate callback for VFs to get/set RSS
configuration.

Add support to control rx-flow-hash based on VLAN.
By default VLAN plus 4-tuple based hashing is enabled.
Changes can be done runtime using ethtool
To enable 2-tuple plus VLAN based flow distribution
# ethtool -N <intf> rx-flow-hash <prot> sdv
To enable 4-tuple plus VLAN based flow distribution
# ethtool -N <intf> rx-flow-hash <prot> sdfnv

This patch adds PTP clock and uses it in Octeontx2
network device. PTP clock uses mailbox calls to
access the hardware counter on the RVU side.

Added ethtool support for VF devices for
- Driver stats, Tx/Rx perqueue stats
- Set/show Rx/Tx queue count
- Set/show Rx/Tx ring sizes
- Set/show IRQ coalescing parameters
- RSS configuration etc
It's the PF which owns the interface, hence VF
cannot display underlying CGX interface stats.
Except for this rest ethtool support reuses PF's
APIs.

Added mailbox requests to retrieve backpressure IDs from AF and Aura,
CQ contexts are configured with these BPIDs. So that when resource
levels reach configured thresholds they assert backpressure on the
interface which is also mapped to same BPID.
Also added support to enable/disable pause frames generation via ethtool.
