2019-11-13net/mlx5: Add new chain for netfilter flow table offloadPaul Blakey2-5/+13
Netfilter tables (nftables) implements a software datapath that comes after tc ingress datapath. The datapath supports offloading such rules via the flow table offload API. This API is currently only used by NFT and it doesn't provide the global priority in regards to tc offload, so we assume offloading such rules must come after tc. It does provide a flow table priority parameter, so we need to provide some supported priority range. For that, split fastpath prio to two, flow table offload and tc offload, with one dedicated priority chain for flow table offload. Next patch will re-use the multi chain API to access this chain by allowing access to this chain by the fdb_sub_namespace.

2019-11-13net/mlx5: Accumulate levels for chains prio namespacesPaul Blakey2-2/+10
Tc chains are implemented by creating a chained prio steering type, and inside it there is a namespace for each chain (FDB_TC_MAX_CHAINS). Each of those has a list of priorities. Currently, all namespaces in a prio start at the parent prio level. But since we can jump from chain (namespace) to another chain in the same prio, we need the levels for higher chains to be higher as well. So we created unused prios to account for levels in previous namespaces. Fix that by accumulating the namespaces levels if we are inside a chained type prio, and removing the unused prios.

The one by Andy Shevchenko removes the legacy platform data support from the driver. The other two are by Timo Schlüßler and reset the device only when needed, to prevent glitches on the output when GPIO support is added. I'm contributing two patches fixing checkpatch warnings in the c_can_platform and peak_canfd driver. Stephane Grosjean's patch for the peak_canfd driver adds hw timestamps support in rx skbs. The next three patches target the xilinx_can driver. One patch by me to fix checkpatch warnings, one patch by Anssi Hannula to avoid non requested bus error frames, and a patch by YueHaibing that switches the driver to devm_platform_ioremap_resource(). Pankaj Sharma contributes two patches for the m_can driver, the first one adds support for one shot mode, the other support for handling arbitration errors. Followed by four patches by YueHaibing, switching the grcan, ifi, rcar, and sun4i drivers to devm_platform_ioremap_resource() I'm contributing cleanup patches for the rx-offload helper, while Joakim Zhang's patch prepares the rx-offload helper for CAN-FD support.
