2022-05-06nfp: flower: add/remove predt_list entriesLouis Peens
Add calls to add and remove flows to the predt_table. This very simply just allocates and add a new pretun entry if detected as such, and removes it when encountered on a delete flow. Compatibility for older firmware is kept in place through the DECAP_V2 feature bit.

2022-05-06nfp: flower: add infrastructure for pre_tun reworkLouis Peens
The previous implementation of using a pre_tun_table for decap has some limitations, causing flows to end up unoffloaded when in fact we are able to offload them. This is because the pre_tun_table does not have enough matching resolution. The next step is to instead make use of the neighbour table which already exists for the encap direction. This patch prepares for this by: - Moving nfp_tun_neigh/_v6 to main.h. - Creating two new "wrapping" structures, one to keep track of neighbour entries (previously they were send-and-forget), and another to keep track of pre_tun flows. - Create a new list in nfp_flower_priv to keep track of pre_tunnel flows - Create a new table in nfp_flower_priv to keep track of next neighbour entries - Initialising and destroying these new list/tables - Extending nfp_fl_payload->pre_tun_rule to save more information for future use.

2022-05-02nfp: support VxLAN inner TSO with GSO_PARTIAL offloadFei Qin
VxLAN belongs to UDP-based encapsulation protocol. Inner TSO for VxLAN packet with udpcsum requires offloading of outer header csum. The device doesn't support outer header csum offload. However, inner TSO for VxLAN with udpcsum can still work with GSO_PARTIAL offload, which means outer udp csum computed by stack and inner tcp segmentation finished by hardware. Thus, the patch enable features "NETIF_F_GSO_UDP_TUNNEL_CSUM" and "NETIF_F_GSO_PARTIAL" and set gso_partial_features.

2022-03-21nfp: nfdk: implement xdp tx path for NFDKYinjun Zhang
Due to the different definition of txbuf in NFDK comparing to NFD3, there're no pre-allocated txbufs for xdp use in NFDK's implementation, we just use the existed rxbuf and recycle it when xdp tx is completed. For each packet to transmit in xdp path, we cannot use more than `NFDK_TX_DESC_PER_SIMPLE_PKT` txbufs, one is to stash virtual address, and another is for dma address, so currently the amount of transmitted bytes is not accumulated. Also we borrow the last bit of virtual addr to indicate a new transmitted packet due to address's alignment attribution.

2022-03-21nfp: add support for NFDK data pathJakub Kicinski
Add new data path. The TX is completely different, each packet has multiple descriptor entries (between 2 and 32).

There is no support for VLAN insertion on TX. XDP_TX action and AF_XDP zero-copy is not implemented in NFDK path.

2022-03-11nfp: parametrize QCP offset/size using dev_infoJakub Kicinski
The queue controller (QCP) is accessed based on a device specific offset. The NFP3800 device also supports more queues. Furthermore, the NFP3800 VFs also access the QCP differently to how the NFP6000 VFs accesses it, though still indirectly. Fortunately, we can remove the offset all together for both VF types. This is safe for NFP6000 VFs since the offset was effectively a wrap around and only used for convenience to have it set the same as the NFP6000 PF.

Multiple writes cause intermediate pointer values that do not end on complete TX descriptors. The QCP peripheral on the NFP provides a number of access modes. In some access modes, the maximum amount to add must be restricted to a 6bit value. The particular access mode used by _nfp_qcp_ptr_add() has no such restrictions, so the "< NFP_QCP_MAX_ADD" test is unnecessary.

2022-02-28flow_offload: reject offload for all drivers with invalid police parametersJianbo Liu
As more police parameters are passed to flow_offload, driver can check them to make sure hardware handles packets in the way indicated by tc. The conform-exceed control should be drop/pipe or drop/ok. Besides, for drop/ok, the police should be the last action. As hardware can't configure peakrate/avrate/overhead, offload should not be supported if any of them is configured.
