From: Sathya Perla <redacted> This patch adds support for offloading TC based flow rules and actions for the 'flower' classifier in the bnxt_en driver. It includes logic to parse flow rules and actions received from the TC subsystem, store them and issue the corresponding hwrm_cfa_flow_alloc/free FW cmds. L2/IPv4/IPv6 flows and drop, redir, vlan push/pop actions are supported in this patch. In this patch the hwrm_cfa_flow_xxx routines are just stubs. The code for these routines is introduced in the next patch for easier review. Also, the code to query the TC/flower action stats will be introduced in a subsequent patch.
Hi.
You are missing checks for the offload. Please see nfp as an example:
Function nfp_flower_setup_tc:
!is_classid_clsact_ingress(cls_flower->common.classid) ||
cls_flower->common.chain_index)
Do you support both ingress and egress or ingress only?
You certainly don't support multichain.
