[Intel-wired-lan] [RFC 00/20] Enable Intel VF flow director with DDP

[Haiyue Wang <haiyue.wang@intel.com>]

The Intel E810 Series supports a programmable pipeline for a domain
specific protocols classification, for example GTP by Dynamic Device
Personalization (DDP) profile.

The E810 PF has introduced flex-bytes support by ethtool user-def option
allowing for packet deeper matching based on an offset and value for DDP
usage.

For making VF also benefit from this flexible protocol classification, some
new virtchnl messages are defined and handled by PF, so VF can query this
new flow director capability, and use ethtool with extending the user-def
option to configure Rx flow classification.

The new user-def 0xAAAABBBBCCCCDDDD: BBBB is the 2 byte pattern while AAAA
corresponds to its offset in the packet. Similarly DDDD is the 2 byte
pattern with CCCC being the corresponding offset. The offset ranges from
0x0 to 0x1F7 (up to 504 bytes into the packet). The offset starts from
the beginning of the packet.

This feature can be used to allow customers to set flow director rules
for protocols headers that are beyond standard ones supported by ethtool
(e.g. PFCP or GTP-U).

Like for matching GTP-U's TEID value 0x10203040:
ethtool -N ens787f0v0 flow-type udp4 dst-port 2152 \
    user-def 0x002e102000303040 action 13
