Hi! This series from John adds bond offload to the nfp driver. Patch 5 exposes the hash type for NETDEV_LAG_TX_TYPE_HASH to make sure nfp hashing matches that of the software LAG. This may be unnecessarily conservative, let's see what LAG maintainers think :)
John says: This patchset sets up the infrastructure and offloads output actions for when a TC flower rule attempts to egress a packet to a LAG port. Firstly it adds some of the infrastructure required to the flower app and to the nfp core. This includes the ability to change the MAC address of a repr, a function for combining lookup and write to a FW symbol, and the addition of private data to a repr on a per app basis. Patch 6 continues by implementing notifiers that track Linux bonds and communicates to the FW those which enslave reprs, along with the current state of reprs within the bond. Patch 7 ensures bonds are synchronised with FW by receiving and acting upon cmsgs sent to the kernel. These may request that a bond message is retransmitted when FW can process it, or may request a full sync of the bonds defined in the kernel. Patch 8 offloads a flower action when that action requires egressing to a pre-defined Linux bond.
