DMAC at all into the key. Hence allow mkex profiles which do not
have DMAC to be loaded into MCAM hardware. This patch also adds
debugging prints needed to identify profiles with wrong
configuration.

then Rx multicast and broadcast entry should be configured.

The user supplies the "count" value to say how big its read buffer is.
The rvu_dbg_lmtst_map_table_display() function does not take the "count"
into account but instead just copies the whole table, potentially
corrupting the user's data.

Introduce the "ret" variable to store how many bytes we can copy.  Also

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

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.

AF till now only manages the allocation and freeing of

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

those are not allocated to AF nor PF/VFs.

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.

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 \

OcteonTx2's next gen platform the CN10K has RPM MAC which has a
different serdes when compared to CGX MAC. Though the underlying
HW is different, the CSR interface has been designed largely inline
with CGX MAC, with few exceptions though. So we are using the same
CGX driver for RPM MAC as well and will have a different set of APIs
for RPM where ever necessary.

This patch adds initial support for CN10K's RPM MAC i.e. the driver
registration, communication with firmware etc. For communication with
firmware, RPM provides a different IRQ when compared to CGX.
The CGX and RPM blocks support different features. Currently few
features like ptp, flowcontrol and higig are not supported by RPM. This
patch adds new mailbox message "CGX_FEATURES_GET" to get the list of
features supported by underlying MAC.

RPM has different implementations for RX/TX stats. Unlike CGX,
bar offset of stat registers are different. This patch adds
support to access the same and dump the values in debugfs.

Unlike earlier silicon variants, OcteonTx2 98xx
silicon has 2 NIX blocks and each of the CGX is
mapped to either of the NIX blocks. Each NIX
block supports 100G. Mapping btw NIX blocks and
CGX is done by firmware based on CGX speed config
to have a maximum possible network bandwidth.
Since the mapping is not fixed, it's difficult
for a user to figure out. Hence added a debugfs
entry which displays mapping between CGX LMAC,
NIX block and RVU PF.

in directory "/sys/kernel/debug/octeontx2/nix1/".

On 98xx silicon, NPC block has additional
mcam entries, counters and NIX1 interfaces.
Extended set of registers are present for the
new mcam entries and counters.
This patch does the following:
- updates the register accessing macros
  to use extended set if present.
- configures the MKEX profile for NIX1 interfaces also.
- updates mcam entry write functions to use assigned
  NIX0/1 interfaces for the PF/VF.
