49f02e6877 Octeontx2-af: Debugfs support for firmware data
MAC address, Link modes (supported and advertised) and eeprom data
for the Netdev interface are read from the shared firmware data.
This patch adds debugfs support for the same.

25d51ebf0f octeontx2: Set appropriate PF, VF masks and shifts based on silicon
Number of RVU PFs on CN20K silicon have increased to 96 from maximum
of 32 that were supported on earlier silicons. Every RVU PF and VF is
identified by HW using a 16bit PF_FUNC value. Due to the change in
Max number of PFs in CN20K, the bit encoding of this PF_FUNC has changed.

This patch handles the change by using helper functions(using silicon
check) to use PF,VF masks and shifts to support both new silicon CN20K,
OcteonTx series. These helper functions are used in different modules.

Also moved the NIX AF register offset macros to other files which
will be posted in coming patches.

a6ae712981 octeontx2-af: Fix APR entry mapping based on APR_LMT_CFG
The current implementation maps the APR table using a fixed size,
which can lead to incorrect mapping when the number of PFs and VFs
varies.
This patch corrects the mapping by calculating the APR table
size dynamically based on the values configured in the
APR_LMT_CFG register, ensuring accurate representation
of APR entries in debugfs.

b907194a5d octeontx2-af: Add debugfs support to dump NIX TM topology
This patch adds support to dump NIX transmit queue topology.
There are multiple levels of scheduling/shaping supported by
NIX and a packet traverses through multiple levels before sending
the packet out. At each level, there are set of scheduling/shaping
rules applied to a packet flow.

Each packet traverses through multiple levels
SQ->SMQ->TL4->TL3->TL2->TL1 and these levels are mapped in a parent-child
relationship.

This patch dumps the debug information related to all TM Levels in
the following way.

Example:
$ echo <nixlf> > /sys/kernel/debug/octeontx2/nix/tm_tree
$ cat /sys/kernel/debug/octeontx2/nix/tm_tree

A more desriptive set of registers at each level can be dumped
in the following way.

Example:
$ echo <nixlf> > /sys/kernel/debug/octeontx2/nix/tm_topo
$ cat /sys/kernel/debug/octeontx2/nix/tm_topo

f2e664ad50 octeontx2-af: Support variable number of lmacs
Most of the code in CGX/RPM driver assumes that max lmacs per
given MAC as always, 4 and the number of MAC blocks also as 4.
With this assumption, the max number of interfaces supported is
hardcoded to 16. This creates a problem as next gen CN10KB silicon
MAC supports 8 lmacs per MAC block.

This patch solves the problem by using "max lmac per MAC block"
value from constant csrs and uses cgx_cnt_max value which is
populated based number of MAC blocks supported by silicon.

0daa55d033 octeontx2-af: cn10k: debugfs for dumping LMTST map table
CN10k SoCs use atomic stores of up to 128 bytes to submit
packets/instructions into co-processor cores. The enqueueing is performed
using Large Memory Transaction Store (LMTST) operations. They allow for
lockless enqueue operations - i.e., two different CPU cores can submit
instructions to the same queue without needing to lock the queue or
synchronize their accesses.

This patch implements a new debugfs entry for dumping LMTST map
table present on CN10K, as this might be very useful to debug any issue
in case of shared LMTST region among multiple pci functions.

e77bcdd1f6 octeontx2-af: Display all enabled PF VF rsrc_alloc entries.
Currently, we are using a fixed buffer size of length 2048 to display
rsrc_alloc output. As a result a maximum of 2048 characters of
rsrc_alloc output is displayed, which may lead sometimes to display only
partial output. This patch fixes this dependency on max limit of buffer
size and displays all PF VF entries.

Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12
characters to print the list of LFs of each block for a PF/VF. If the
length of list of LFs of a block exceeds this fixed width then the list
gets truncated and displays only a part of the list. This patch fixes
this by using the maximum possible length of list of LFs among all
blocks of all PFs and VFs entries as the width size.

cb7a6b3bac octeontx2-af: Prepare for allocating MCAM rules for AF
AF till now only manages the allocation and freeing of
MCAM rules for other PF/VFs in system. To implement
L2 switching between all CGX mapped PF and VFs, AF
requires MCAM entries for DMAC rules for each PF and VF.
This patch modifies AF driver such that AF can also
allocate MCAM rules and install rules for other
PFs and VFs. All the checks like channel verification
for RX rules and PF_FUNC verification for TX rules are
relaxed in case AF is allocating or installing rules.
Also all the entry and counter to owner mappings are
set to NPC_MCAM_INVALID_MAP when they are free indicating
those are not allocated to AF nor PF/VFs.
This patch also ensures that AF allocated and installed
entries are displayed in debugfs.

967db3529e octeontx2-af: add support for multicast/promisc packet replication feature
Currently, multicast packet filtering is accomplished by installing
MCAM rule that matches all-multicast MAC address and has its
NPC_RX_ACTION set to unicast to PF. Similarly promisc feature is
achieved by installing MCAM rule that matches all the traffic received
by the channel and unicast the packets to PF. This approach only applies
to PF and is not scalable across VFs.

This patch adds support for PF/VF multicast and promisc feature by
reserving NIX_RX_MCE_S entries from the global MCE list allocated
during NIX block initialization. The NIX_RX_MCE_S entries create a
linked list with a flag indicating the end of the list, and each entry
points to a PF_FUNC (either PF or VF). When a packet NPC_RX_ACTION is
set to MCAST, the corresponding NIX_RX_MCE_S list is traversed and the
packet is queued to each PF_FUNC available on the list.

The PF or VF driver adds the multicast/promisc packet match entry and
updates the MCE list with correspondng PF_FUNC. When a PF or VF interface
is disabled, the corresponding NIX_RX_MCE_S entry is removed from the
MCE list and the MCAM entry will be disabled if the list is empty.

1d4d9e42c2 octeontx2-pf: Add tc flower hardware offload on ingress traffic
This patch adds support for tc flower hardware offload on ingress
traffic. Since the tc-flower filter rules use the same set of MCAM
rules as the n-tuple filters, the n-tuple filters and tc flower
rules are mutually exclusive. When one of the feature is enabled
using ethtool, the other feature is disabled in the driver. By default
the driver enables n-tuple filters during initialization.

The following flow keys are supported.
    -> Ethernet: dst_mac
    -> L2 proto: all protocols
    -> VLAN (802.1q): vlan_id/vlan_prio
    -> IPv4: dst_ip/src_ip/ip_proto{tcp|udp|sctp|icmp}/ip_tos
    -> IPv6: ip_proto{icmpv6}
    -> L4(tcp/udp/sctp): dst_port/src_port

The following flow actions are supported.
    -> drop
    -> accept
    -> redirect
    -> vlan pop

The flow action supports multiple actions when vlan pop is specified
as the first action. The redirect action supports redirecting to the
PF/VF of same PCI device. Redirecting to other PCI NIX devices is not
supported.

Example #1: Add a tc filter rule to drop UDP traffic with dest port 80
    # ethtool -K eth0 hw-tc-offload on
    # tc qdisc add dev eth0 ingress
    # tc filter add dev eth0 protocol ip parent ffff: flower ip_proto \
          udp dst_port 80 action drop

Example #2: Add a tc filter rule to redirect ingress traffic on eth0
with vlan id 3 to eth6 (ex: eth0 vf0) after stripping the vlan hdr.
    # ethtool -K eth0 hw-tc-offload on
    # tc qdisc add dev eth0 ingress
    # tc filter add dev eth0 parent ffff: protocol 802.1Q flower \
          vlan_id 3 vlan_ethtype ipv4 action vlan pop action mirred \
          ingress redirect dev eth6

Example #3: List the ingress filter rules
    # tc -s filter show dev eth4 ingress

Example #4: Delete tc flower filter rule with handle 0x1
    # tc filter del dev eth0 ingress protocol ip pref 49152 \
      handle 1 flower
