Add plumbing to allow DSA drivers to register parameters with devlink. To keep with the abstraction, the DSA drivers pass the ds structure to these helpers, and the DSA core then translates that to the devlink structure associated to the device.

In preparation for supporting IGMP snooping with or without the use of a bridge, add support within b53_common.c to program the ARL entries for multicast operations. The key difference is that a multicast ARL entry is comprised of a bitmask of enabled ports, instead of a port number.

Matteo Croce says: ==================== mvpp2 improvements in rx path Refactor some code in the RX path to allow prefetching some data from the packet header. The first patch is only a refactor, the second one reduces the data synced, while the third one adds the prefetch.

When receiving traffic, eth_type_trans() is high up on the perf top list, because it's the first function which access the packet data. Move the DMA unmap a bit higher, and put a prefetch just after it, so we have more time to load the data into the cache.

Since commit 0394a63a ("net: dsa: enable and disable all ports") the dsa core disables all unused ports of a switch. In this case disabling ports with numbers higher than QCA8K_NUM_PORTS causes that some switch registers are overwritten with incorrect content.

Daniel Borkmann says: ==================== pull-request: bpf-next 2019-10-27 The following pull-request contains BPF updates for your *net-next* tree. We've added 52 non-merge commits during the last 11 day(s) which contain a total of 65 files changed, 2604 insertions(+), 1100 deletions(-). The main changes are: 1) Revolutionize BPF tracing by using in-kernel BTF to type check BPF assembly code. The work here teaches BPF verifier to recognize kfree_skb()'s first argument as 'struct sk_buff *' in tracepoints such that verifier allows direct use of bpf_skb_event_output() helper used in tc BPF et al (w/o probing memory access) that dumps skb data into perf ring buffer. Also add direct loads to probe memory in order to speed up/replace bpf_probe_read() calls, from Alexei Starovoitov. 2) Big batch of changes to improve libbpf and BPF kselftests. Besides others: generalization of libbpf's CO-RE relocation support to now also include field existence relocations, revamp the BPF kselftest Makefile to add test runner concept allowing to exercise various ways to build BPF programs, and teach bpf_object__open() and friends to automatically derive BPF program type/expected attach type from section names to ease their use, from Andrii Nakryiko. 3) Fix deadlock in stackmap's build-id lookup on rq_lock(), from Song Liu. 4) Allow to read BTF as raw data from bpftool. Most notable use case is to dump /sys/kernel/btf/vmlinux through this, from Jiri Olsa. 5) Use bpf_redirect_map() helper in libbpf's AF_XDP helper prog which manages to improve "rx_drop" performance by ~4%., from Björn Töpel. 6) Fix to restore the flow dissector after reattach BPF test and also fix error handling in bpf_helper_defs.h generation, from Jakub Sitnicki. 7) Improve verifier's BTF ctx access for use outside of raw_tp, from Martin KaFai Lau. 8) Improve documentation for AF_XDP with new sections and to reflect latest features, from Magnus Karlsson. 9) Add back 'version' section parsing to libbpf for old kernels, from John Fastabend. 10) Fix strncat bounds error in libbpf's libbpf_prog_type_by_name(), from KP Singh. 11) Turn on -mattr=+alu32 in LLVM by default for BPF kselftests in order to improve insn coverage for built BPF progs, from Yonghong Song. 12) Misc minor cleanups and fixes, from various others. ==================== Signed-off-by: NDavid S.

Even out Rx performance across MTU sizes by changing from full skb allocations to page-based frag allocations. The device supports a form of scatter-gather in the Rx path, so we can set up a number of pages for each descriptor, all of which are easier to alloc and pass around than the standard kzalloc'd buffer. An skb is wrapped around the pages while processing the received packets, and pages are recycled as needed, or left alone if they weren't used in the Rx.

The TCPI_OPT_SYN_DATA bit as part of tcpi_options currently reports whether or not data-in-SYN was ack'd on both the client and server side. We'd like to gather more information on the client-side in the failure case in order to indicate the reason for the failure. This can be useful for not only debugging TFO, but also for creating TFO socket policies. For example, if a middle box removes the TFO option or drops a data-in-SYN, we can can detect this case, and turn off TFO for these connections saving the extra retransmits. The newly added tcpi_fastopen_client_fail status is 2 bits and has the following 4 states: 1) TFO_STATUS_UNSPEC Catch-all state which includes when TFO is disabled via black hole detection, which is indicated via LINUX_MIB_TCPFASTOPENBLACKHOLE. 2) TFO_COOKIE_UNAVAILABLE If TFO_CLIENT_NO_COOKIE mode is off, this state indicates that no cookie is available in the cache. 3) TFO_DATA_NOT_ACKED Data was sent with SYN, we received a SYN/ACK but it did not cover the data portion. Cookie is not accepted by server because the cookie may be invalid or the server may be overloaded. 4) TFO_SYN_RETRANSMITTED Data was sent with SYN, we received a SYN/ACK which did not cover the data after at least 1 additional SYN was sent (without data). It may be the case that a middle-box is dropping data-in-SYN packets. Thus, it would be more efficient to not use TFO on this connection to avoid extra retransmits during connection establishment. These new fields do not cover all the cases where TFO may fail, but other failures, such as SYN/ACK + data being dropped, will result in the connection not becoming established. And a connection blackhole after session establishment shows up as a stalled connection.

The link detection timeouts can be observed (or link might not be detected at all) when dp83867 PHY is configured in manual mode (speed/duplex). CFG3[9] Robust Auto-MDIX option allows to significantly improve link detection in case dp83867 is configured in manual mode and reduce link detection time. As per DM: "If link partners are configured to operational modes that are not supported by normal Auto MDI/MDIX mode (like Auto-Neg versus Force 100Base-TX or Force 100Base-TX versus Force 100Base-TX), this Robust Auto MDI/MDIX mode allows MDI/MDIX resolution and prevents deadlock." Hence, enable this option by default as there are no known reasons not to do so.
