[dpdk-dev] [PATCH v5 1/3] ethdev: add neighbor discovery support to flow API

Adrien Mazarguil adrien.mazarguil at 6wind.com
Tue Apr 24 17:58:58 CEST 2018


From: Qi Zhang <qi.z.zhang at intel.com>

- RTE_FLOW_ITEM_TYPE_ARP_ETH_IPV4: matches an ARP header for Ethernet/IPv4.

- RTE_FLOW_ITEM_TYPE_IPV6_EXT: matches the presence of any IPv6 extension
  header.

- RTE_FLOW_ITEM_TYPE_ICMP6: matches any ICMPv6 header.

- RTE_FLOW_ITEM_TYPE_ICMP6_ND_NS: matches an ICMPv6 neighbor discovery
  solicitation.

- RTE_FLOW_ITEM_TYPE_ICMP6_ND_NA: matches an ICMPv6 neighbor discovery
  advertisement.

- RTE_FLOW_ITEM_TYPE_ICMP6_ND_OPT: matches the presence of any ICMPv6
  neighbor discovery option.

- RTE_FLOW_ITEM_TYPE_ICMP6_ND_OPT_ETH_SLA: matches an ICMPv6 neighbor
  discovery source Ethernet link-layer address option.

- RTE_FLOW_ITEM_TYPE_ICMP6_ND_OPT_ETH_TLA: matches an ICMPv6 neighbor
  discovery target Ethernet link-layer address option.

v5 changes:

- Clarified ITEM_ARP_IPV4 as ITEM_ARP_ETH_IPV4.
- Expanded abbreviated macros (e.g. ITEM_ICMP6_ND_NS_TGT_ADDR =>
  ITEM_ICMP6_ND_NS_TARGET_ADDR) to match the name of the underlying
  structure field.
- Fixed testpmd flow command issues (lack of ITEM_NEXT, use of UNSIGNED
  instead of IPV4_ADDR/IPV6_ADDR/MAC_ADDR).
- Clarified/fixed flow command help strings and matching documentation.
- Added ITEM_ICMP6_ND_OPT for generic ND options.
- Modified ITEM_ICMP6_ND_OPT_SLA_ETH and ITEM_ICMP6_ND_OPT_TLA_ETH to not
  include an ICMPv6 header but instead work like ITEM_ICMP6_ND_OPT as
  separate items to stack on top of ICMPv6 ND on a needed basis.
- Updated documentation accordingly.
- Added these new pattern items to rte_flow_copy().
- Updated commit log to reflect patch contents.
