In the rtl8366rb driver there are some jam tables which contain undocumented values. While trying to understand what these tables actually do, I noticed a discrepancy in how one of those was treated. Most of them were plain u16 arrays, while the ethernet one was an u16 matrix. By looking at the vendor's droplets of source code these tables came from, I found out that they were all originally u16 matrixes. This commit standardizes the jam tables, turning them all into jam_tbl_entry arrays. Each entry contains 2 u16 values. This change makes it easier to understand how the jam tables are used and also makes it possible for a single function to handle all of them, removing some duplicated code. Signed-off-by:

Saeed Mahameed says: ==================== mlx5 devlink traps support Add support for devlink traps [1] reporting in mlx5, mlx5 will also report/trap packets filtered due to dest mac steering miss The first patch in the series defines the new DMAC trap type in devlink for this purpose. Other patches in the series are mlx5 only and they gradually traps support. Supported traps: DMAC: Drops due to destination MAC not configured in the MAC table VLAN: Drops due to vlan not configured in the vlan table Design note: devlink instance is managed by the low level mlx5 core layer, mlx5 core will serve as an abstraction layer for trap reporting, since we might have multiple mlx5 interfaces who might want to report traps on the same device. ==================== Link: https://lore.kernel.org/r/20210126232419.175836-1-saeedm@nvidia.comSigned-off-by:

Avoid trapping packets when the interface is down, and revive them when interface is back up. Add API to mlx5 core retrieving the action by trap id. Use it to apply traps when interface is up, and disable then when interface is down. Signed-off-by:

Add support for listening to blocking events in the ETH driver. Listen on trap event. If received, call mlx5e_handle_trap_event() which: 1) Verifies if driver needs open/close trap-RQ with respect to the active traps count. 2) Inspects trap id and its action (trap/drop) and add/remove the flow steering rule accordingly. Otherwise, return an error. Signed-off-by:

Introduce mlx5e_trap which includes a dedicated RQ and NAPI for trapped packets. Trap-RQ processes packets that were destined to be dropped, but for debug and visibility sake these packets are trapped and reported to devlink. Trap-RQ connects between the HW and the driver and is not a part of a channel. Open mlx5e_create_rq() and mlx5_core_destroy_rq() as API and add dedicate RQ handlers which report to devlink of trapped packets. Signed-off-by:

Change steering flow to optimize traffic in promiscuous mode. On demand, add a high priority table containing a catch-all rule. All incoming packets are caught by this rule and steered directly to the TTC table. Prior to this change, packets in promiscuous mode may suffer from up to 4 steering hops before reaching TTC table. In addition, this patch will allow us adding a catch-all rule at the end of MAC table to serve MAC trap, with no impact on promiscuous mode performance. Signed-off-by:

Early generations of the mv88e6xxx did not have the global 2 registers. In order to keep the driver slim, it was decided to make the code for these registers optional. Over time, more generations of switches have been added, always supporting global 2 and adding more and more registers. No effort has been made to keep these additional registers also optional to slim the driver down when used for older generations. Optional global 2 now just gives additional development and maintenance burden for no real gain. Make global 2 support always compiled in. Signed-off-by:

The next patch is by Vincent Mailhol and targets the CAN driver infrastructure, it exports the function that converts the CAN state into a human readable string. A patch by me, which target the CAN driver infrastructure, too, makes the calculation in can_fd_len2dlc() more readable. A patch by Tom Rix fixes a checkpatch warning in the mcba_usb driver. The next seven patches target the mcp251xfd driver. Su Yanjun's patch replaces several hardcoded assumptions when calling regmap, by using regmap_get_val_bytes(). The remaining patches are by me. First an open coded check is replaced by an existing helper function, then in the TX path the padding for CAN-FD frames is cleaned up. The next two patches clean up the RTR frame handling in the RX and TX path. Then support for len8_dlc is added.

Then patch 02 adds the ability to configure and retrieve the hosts limit and to retrieve the current number of tracked hosts per port.

Patches 1 and 2 handle the conversion and comparison of the mapped addresses. Patch 3 contains a minor refactor in the path manager's handling of addresses.

Here, we make sure we support IPv4-mapped in IPv6 addresses in different contexts: - a v4-mapped address is received by the PM and can be used as v4. - a v4 address is received by the PM and can be used even with a v4 mapped socket. We also make sure we don't try to establish subflows between v4 and v6 addresses, e.g. if a real v6 address ends with a valid v4 address. Co-developed-by:

On one side, we can allow the creation of subflows between v4 mapped in v6 and v4 addresses. For that we look for v4mapped addresses between the local address we want to select and the remote one. On the other side, we also properly deal with received v4mapped addresses, either announced ones or set via Netlink. Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/122Suggested-by:

With an IPv4 mapped in v6 socket, we were trying to call inet6_bind() with an IPv4 address resulting in a -EINVAL error because the given addr_len -- size of the address structure -- was too short. We now make sure to use address structures for the same family as the MPTCP socket for both the bind() and the connect(). It means we convert v4 addresses to v4 mapped in v6 or the opposite if needed. Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/122Co-developed-by:

pktgen create threads for all online cpus and bond these threads to relevant cpu repecivtily. when this thread firstly be woken up, it will compare cpu currently running with the cpu specified at the time of creation and if the two cpus are not equal, BUG_ON() will take effect causing panic on the system. Notice that these threads could be migrated to other cpus before start running because of the cpu hotplug after these threads have created. so the BUG_ON() used here seems unreasonable and we can replace it with WARN_ON() to just printf a warning other than panic the system.
