Subject: [v1 0/4] Add support for GRE optional fields matching
Date: Wed, 26 Jan 2022 10:44:00 +0200	[thread overview]
Message-ID: <20220126084404.40178-1-xiazhang@nvidia.com> (raw)
In-Reply-To: <20211230030817.15264-2-xiazhang@nvidia.com>

This patch set adds support for matching optional fields of GRE header.
The optional fields are checksum, key and sequence number. Currently, key
field is supported with pattern gre_key item '.. / gre / gre_key value is
xx / ..' with field gre_key in misc, but misc does not support matching of
checksum and sequence number of GRE.
To support matching of checksum and sequence number fields in GRE,
rdma-core needs the capbility of misc5 and support tunnel_header 0-3. Since
tunnel_header1 is used to match checksum, tunnel_header2 for key and
tunnel_header3 for sequence by hardware. If checksum and sequence number
not present in the pattern, use misc as before for the matching.
Application can still use gre_key item 'gre_key value is xx' for key
matching, the effect is the same if use 'gre_option key is xx'.
If using gre_option item, the flags in gre item should be correspondingly
set. For example, if using gre_option to match checksum, the c_bit should
be set '1' (.. / gre c_bit is 1 / gre_option checksum is xx / ..).
