Alex Elder says: ==================== net: ipa: memory region rework, part 2 This is the second portion of a set of patches updating the IPA memory region code. In this portion (part 2), the focus is on adjusting the code so that it no longer assumes the memory region descriptor array is indexed by the region identifier. This brings with it some related cleanup. Three loops are changed so their loop index variable is an unsigned rather than an enumerated type. A set of functions is changed so a region identifier (rather than a memory region descriptor pointer) is passed as argument, to simplify their call sites. This isn't entirely related or required, but I think it improves the code. A validation function for filter and route table memory regions is changed to take memory region IDs, rather than determining which region to validate based on a set of Boolean flags. Finally, ipa_mem_find() is created to abstract getting a memory descriptor based on its ID, and it is used everywhere rather than indexing the array. With that implemented, all of the memory regions can be defined by arrays of entries defined without providing index designators. ==================== Signed-off-by: -

Finally the code handles the IPA memory region array in the configuration data without assuming it is indexed by region ID. Get rid of the array index designators where these arrays are initialized. As a result, there's no more need to define an explicitly undefined memory region ID, so get rid of that. Change ipa_mem_find() so it no longer assumes the ipa->mem[] array is indexed by memory region ID. Instead, have it search the array for the entry having the requested memory ID, and return the address of the descriptor if found. Otherwise return NULL. Stop allowing memory regions to be defined with zero size and zero canary value. Check for this condition in ipa_mem_valid_one(). As a result, it is not necessary to check for this case in ipa_mem_config(). Finally, there is no need for IPA_MEM_UNDEFINED to be defined any more, so get rid of it. Signed-off-by:

Introduce a new function that abstracts finding information about a region in IPA-local memory, given its memory region ID. For now it simply uses the region ID as an index into the IPA memory array. If the region is not defined, ipa_mem_find() returns a null pointer. Update all code that accesses the ipa->mem[] array directly to use ipa_mem_find() instead. The return value must be checked for null when optional memory regions are sought. Signed-off-by:

Stop passing most of the Boolean flags to ipa_table_valid_one(), and just pass a memory region ID to it instead. We still need to indicate whether we're operating on a routing or filter table. Signed-off-by:

Pass a memory region ID rather than the address of a memory region descriptor to ipa_table_reset_add() to simplify callers. Similarly, pass memory region IDs to ipa_table_init_add(). Signed-off-by:

Pass a memory region ID rather than the address of a memory region descriptor to ipa_filter_reset_table(), to simplify callers. We can eliminate the check for a zero region size in this function because ipa_table_reset_add() checks that before adding anything to the transaction. Note that here and in subsequent commits there is no need to check whether a memory region exists, because we will have already verified that during initialization. Signed-off-by:

Do some general cleanup in ipa_cmd_header_valid(): - Delay assigning the mem variable until just before it's used. - Assign the maximum offset and size values together. - Improve comments explaining the single range of memory being made up of a modem portion and an AP portion. - Record the offset of the combined range in a local variable. - Do the initial size assignment right after assigning the offset.

Change ipa_mem_valid() to iterate over the entries using a u32 index variable rather than using a memory region ID. Use the ID found inside the memory descriptor rather than the loop index. Change ipa_mem_size_valid() to iterate over the entries but without assuming the array index is the memory region ID. "Empty" entries will have zero size; and we'll temporarily assume such entries have zero offset as well (they all do, currently). Similarly, don't assume the mem[] array is indexed by ID in ipa_mem_config(). There, "empty" entries will have a zero canary count, so no special assumptions are needed to handle them correctly.

Allow the device to be initialized at a later time if it is not available at boot. The device will be allowed to probe but will be given a "down" state. After completing device probe and registering the net device, the driver will await an interrupt signal from its partner device, indicating that it is ready for boot. The driver will schedule a work event to perform the necessary procedure and begin operation. Co-developed-by:

Vadym Kochan says: ==================== net: marvell: prestera: add LAG support The following features are supported: - LAG basic operations - create/delete LAG - add/remove a member to LAG - enable/disable member in LAG - LAG Bridge support - LAG VLAN support - LAG FDB support Limitations: - Only HASH lag tx type is supported - The Hash parameters are not configurable. They are applied during the LAG creation stage. - Enslaving a port to the LAG device that already has an upper device is not supported. Changes extracted from: https://lkml.org/lkml/2021/2/3/877 and marked with "v2". v2: There are 2 additional preparation patches which simplifies the netdev topology handling. 1) Initialize 'lag' with NULL in prestera_lag_create() [suggested by Vladimir Oltean] 2) Use -ENOSPC in prestera_lag_port_add() if max lag [suggested by Vladimir Oltean] numbers were reached. 3) Do not propagate netdev events to prestera_switchdev [suggested by Vladimir Oltean] but call bridge specific funcs. It simplifies the code. 4) Check on info->link_up in prestera_netdev_port_lower_event() [suggested by Vladimir Oltean] 5) Return -EOPNOTSUPP in prestera_netdev_port_event() in case [suggested by Vladimir Oltean] LAG hashing mode is not supported. 6) Do not pass "lower" netdev to bridge join/leave functions. [suggested by Vladimir Oltean] It is not need as offloading settings applied on particular physical port. It requires to do extra upper dev lookup in case port is in the LAG which is in the bridge on vlans add/del. ==================== Signed-off-by: -

The commit 5a558611 ("net: stmmac: support FPE link partner hand-shaking procedure") introduced the following coverity warning: "Parse warning (PW.MIXED_ENUM_TYPE)" "1. mixed_enum_type: enumerated type mixed with another type" This is due to both "lo_state" and "lp_sate" which their datatype are enum stmmac_fpe_state type, and being assigned with "FPE_EVENT_UNKNOWN" which is a macro-defined of 0. Fixed this by assigned both these variables with the correct enum value. Fixes: 5a558611 ("net: stmmac: support FPE link partner hand-shaking procedure") Signed-off-by:
