Now having a major and a minor number, also print the firmware in human readable form "major.minor". Still keep the 4-digit hexadecimal representation because that form is used in the firmware changelog documents.

In few error cases MAC(CGX/RPM) block is having 0 lmacs. AF driver uses MAC block with lmac pair to get firmware data etc. These commands will fail as there is no LMAC associated with MAC block. This patch skips the probe of these MAC blocks such that AF driver uses correct MAC block and LMAC pair for firmware communication and define new LMAC_AF_ERROR types for command timeout etc. This patch also enables channel back pressure for all LMACs.

Oleksandr Mazur says: ==================== net: marvell: prestera: add MDB offloading support This patch series adds support for the MDB handling for the marvell Prestera Driver. It's used to propagate IGMP groups registered within the Kernel to the underlying HW (offload registered groups). Features: - define (and implement) main internal MDB-related objects; - define (and implement) main HW APIs for MDB handling; - add MDB handling support for both regular ports as well as Bond interfaces; - Mirrored behavior of Bridge driver upon multicast router appearance (all traffic flooded when there's no mcast router; mcast router receives all mcast traffic, and only group-specific registered mcast traffic is being received by ports who've explicitly joined any group when there's a registered mcast router); - Reworked prestera driver bridge flags (especially multicast) setting - thus making it possible to react over mcast disabled messages properly by offloading this state to the underlying HW (disabling multicast flooding); Limitations: - Not full (partial) IGMPv3 support (due to limited switchdev notification capabilities: MDB events are being propagated only with a single MAC entry, while IGMPv3 has Group-Specific requests and responses); - It's possible that multiple IP groups would receive traffic from other groups, as MDB events are being propagated with a single MAC entry, which makes it possible to map a few IPs over same MAC; Co-developed-by:Yevhen Orlov <yevhen.orlov@plvision.eu> Signed-off-by:

Define bridge MDB entry (software entry): - entry that get's created upon receiving MDB management events (create/delete), that inherently defines a software entry, which can be enabled (offloaded to the HW) or disabled (removed from HW). This separation is done to achieve a better highlevel management of HW resources - software MDB entry could exist, while it's not necessarily should be configured on the HW. For example: by default, the Linux behavior would not replicate multicast traffic to multicast group members if there's no active multicast router and thus - no actual multicast traffic can be received/sent. So, until multicast router appears on the system no HW configuration should be applied, although SW MDB entries should be tracked. Another example would be altering state of 'multicast enabled' on the bridge: MC_DISABLED should invoke disabling / clearing multicast groups of specified bridge on the HW, yet upon receiving 'multicast enabled' event, driver should reconfigure any existing software MDB groups on the HW. Keeping track of software MDB entries in such way makes it possible to properly react on such events. Define bridge MDB port entry (software entry): - entry that helps keeping track (on software - driver - level) of which bridge mebemer interface joined any give MDB group; Co-developed-by: -

The current code allows to inherit the TTL (hop_limit) from the payload when skb->protocol is ETH_P_IP or ETH_P_IPV6. However when the payload is VLAN encapsulated (e.g because the tunnel is of type GRETAP), then this inheriting does not work, because the visible skb->protocol is of type ETH_P_8021Q or ETH_P_8021AD. Instead of skb->protocol, use skb_protocol(). Signed-off-by:

When building with Clang we encounter these warnings: | drivers/net/ethernet/qlogic/qed/qed_dev.c:416:30: error: format | specifies type 'char' but the argument has type 'u32' (aka 'unsigned | int') [-Werror,-Wformat] i); - | drivers/net/ethernet/qlogic/qed/qed_dev.c:630:13: error: format | specifies type 'char' but the argument has type 'int' [-Werror,-Wformat] | p_llh_info->num_ppfid - 1); For the first warning, `i` is a u32 which is much wider than the format specifier `%hhd` describes. This results in a loss of bits after 2^7. The second warning involves implicit integer promotion as the resulting type of addition cannot be smaller than an int. example: `` uint8_t a = 4, b = 7; int size = sizeof(a + b - 1); printf("%d\n", size); // output: 4 ``` See more: (https://wiki.sei.cmu.edu/confluence/display/c/INT02-C.+Understand+integer+conversion+rules) "Integer types smaller than int are promoted when an operation is performed on them. If all values of the original type can be represented as an int, the value of the smaller type is converted to an int; otherwise, it is converted to an unsigned int."

Mat Martineau says: ==================== mptcp: Support changes to initial subflow priority This series updates the in-kernel MPTCP path manager to allow changes to subflow priority for the first subflow created for each MPTCP connection (the one created with the MP_CAPABLE handshake). Patches 1 and 2 do some refactoring to simplify the new functionality. Patch 3 introduces the new feature to change the initial subflow priority and send the MP_PRIO header on that subflow. Patch 4 cleans up code related to tracking endpoint ids on the initial subflow. Patch 5 adds a selftest to confirm that subflow priorities are updated as expected. ==================== Link: https://lore.kernel.org/r/20220711191633.80826-1-mathew.j.martineau@linux.intel.comSigned-off-by:

Paolo Abeni authored
Currently the id accounting for the ID 0 subflow is not correct: at creation time we mark (correctly) as unavailable the endpoint id corresponding the MPC subflow source address, while at subflow removal time set as available the id 0. With this change we track explicitly the endpoint id corresponding to the MPC subflow so that we can mark it as available at removal time. Additionally this allow deleting the initial subflow via the NL PM specifying the corresponding endpoint id. Reviewed-by:
-
Paolo Abeni authored
Any local endpoints configured on the address matching the MPC subflow are currently ignored. Specifically, setting a backup flag on them has no effect on the first subflow, as the MPC handshake can't carry such info. This change refactors the MPC endpoint id accounting to additionally fetch the priority info from the relevant endpoint and eventually trigger the MP_PRIO handshake as needed. As a result, the MPC subflow now switches to backup priority after that the MPTCP socket is fully established, according to the local endpoint configuration. Reviewed-by:

Paolo Abeni authored
When looking-up a socket address in the endpoint list, we must prefer port-based matches over address only match. Ensure that port-based endpoints are listed first, using head insertion for them. Additionally be sure that only port-based endpoints carry a non zero port number. Reviewed-by:
