Commit Message

Guo, Jia Oct. 15, 2020, 3:41 a.m. UTC
Enable metadata extraction for flexible descriptors in AVF, that would
allow network function directly get metadata without additional parsing
which would reduce the CPU cost for VFs. The enabling metadata
extractions involve the metadata of VLAN/IPv4/IPv6/IPv6-FLOW/TCP/MPLS
flexible descriptors, and the VF could negotiate the capability of
the flexible descriptor with PF and correspondingly configure the
specific offload at receiving queues.

---
v9:
change the undef config

v8:
rebase patch for apply issue

v7:
clean some useless and add doc

v6:
rebase patch

v5:
remove ovs configure since ovs is not protocol extraction

v4:
add flex desc type in rx queue for handling vector path
handle ovs flex type

v3:
export these global symbols into .map

v2:
remove makefile change and modify the rxdid handling
