Updated NPC KPU packet parsing profile with support for following
- Fragmentation support for IPv4 IPv6 outer header
- NIX instruction header support
- QinQ with TPID of 0x8100 as non inner most vlan tag, as legacy
network equipments still generate QinQ packets with this configuration.
- To better support RSS for tunnelled packets, udp based tunnel
protocols such as vxlan, vxlan-gpe, geneve and gtpu are now
captured into a separate layer E. Consequently, the inner
packet headers are pushed one layer down to LF, LG, and LH
accordingly.
- Support for rfc7510 mpls in udp. Up to 4 MPLS labels can be parsed
and captured in one layer LE.
- Parser support for DSA, extended DSA and eDSA tags right after
ethernet header by Marvell SOHO and Falcon switches. For extended
DSA and eDSA tags, a special PKIND of 62 is used, as these tags don't
contain a tpid field.
- Higig2 protocol header parsing support, added a NPC_LT_LA_HIGIG2_ETHER
for a combined header of HIGIG2 and Ethernet. Add a
NPC_LT_LA_IH_NIX_HIGIG2_ETHER for a combined header of nix_ih,
HIGIG2 and Ethernet on egress side. Also added 2 upper flags in LA to
indicate the presence of nix_ih and HIGIG2.
Other changes include
- IPv4.TTL==0 IPv6.HLIM==0 check
- Per RFC 1858, mark fragment offset == 1 as error
- TCP invalid flags check
- Separate error codes for outer and inner IPv4 checksum errors.
- Fix a parser error when KPU parses incoming IPSec ESP and AH packets
- NPC vtag capture/strip hardware expect tag pointer to point to
tpid/ethertype instead of tci. So move lb_ptr to point to tpid/ethertype.
- Fix npc parser error when parsing udp packets that don't have any payload.
- For a single MCAM entry to match on packets with one or stacked vlan tags
combine NPC_LT_LB_STAG and NPC_LT_LB_QINQ to NPC_LT_LB_STAG_QINQ.
- NVGRE to have a separate ltype LD_NVGRE instead of combined with LD_GRE.
- Reserve top LD/LTYPEs to support custom KPU profile fields.

NPC block is responsible for parsing and forwarding
packets to different NIXLFs. NPC has 16 KPU engines
(Kangaroo parse engine) and one iKPU which represents
pkinds. Each physical port either CGX/LBK is assigned
a pkind and upon receiving a packet HW takes that port's
pkind and starts parsing as per the KPU engines config.
This patch adds header files which contain configuration
profile/array for each of the iKPU and 16 KPU engines.
