From: Kishore Padmanabha Date: Fri, 12 Jun 2020 12:50:02 +0000 (+0530) Subject: net/bnxt: support action bitmap opcode X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=52799debdf1c;p=dpdk.git net/bnxt: support action bitmap opcode This enables using the action bitmap to update the action result fields in the flow creation instead of using computed header fields. Direction bit needs to be added to the action bitmap during flow parsing, so that egress flows can be matched to the template signature. An example would be the usage of the vlan pop action bitmap that is used to updated action result field as part of this commit. Also the ulp action bitmap enumeration values that contain open flow string are renamed.
