Currently, this script sets up the test scenario, which is supposed to end in an inability of the system to negotiate a link. It then waits for a bit, and verifies that the system can diagnose why the link was not established. The wait time for the scenario where different link speeds are forced on the two ends of a loopback cable, was set to 4 seconds, which exactly covered it. As of a recent mlxsw firmware update, this time gets longer, and this test starts failing. The time that selftests currently wait for links to be established is currently $WAIT_TIMEOUT, or 20 seconds. It seems reasonable that if this is the time necessary to establish and bring up a link, it should also be enough to determine that a link cannot be established and why. Therefore in this patch, convert the sleeps to busywaits, so that if a failure is established sooner (as is expected), the test runs quicker. And use $WAIT_TIMEOUT as the time to wait. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Unified bridge conversion - part 5/6 This is the fifth part of the conversion of mlxsw to the unified bridge model. The previous part that was merged in commit d521bc0a ("Merge branch 'mlxsw-unified-bridge-conversion-part-4-6'") converted the flooding code to use the new APIs of the unified bridge model. As part of this conversion, the flooding code started accessing the port group table (PGT) directly in order to allocate MID indexes and configure the ports via which a packet needs to be replicated. MDB entries in the device also make use of the PGT table, but the related code has its own PGT allocator and does not make use of the common core that was added in the previous patchset. This patchset converts the MDB code to use the common PGT code. The first nine patches prepare the MDB code for the conversion that is performed by the last patch. ==================== Signed-off-by:

The previous patches added common APIs for maintaining PGT (Port Group Table) table. In the legacy model, software did not interact with this table directly. Instead, it was accessed by firmware in response to registers such as SFTR and SMID. In the new model, software has full control over the PGT table using the SMID register. The configuration of MDB entries is already done via SMID, so the new PGT APIs can be used also using the legacy model, the only difference is that MID index should be aligned to bridge model. See a previous patch which added API for that. The main changes are: - MDB code does not maintain bitmap of ports in MDB entry anymore, instead, it stores a list of ports with additional information. - MDB code does not configure SMID register directly anymore, it will be done via PGT API when port is first added or removed. - Today MDB code does not update SMID when port is added/removed while multicast is disabled. Instead, it maintains bitmap of ports and once multicast is enabled, it rewrite the entry to hardware. Using PGT APIs, the entry will be updated also when multicast is disabled, but the mapping between {MAC, FID}->{MID} will not appear in SFD register. It means that SMID will be updated all the time and disable/enable multicast will impact only SFD configuration. - For multicast router, today only SMID is updated and the bitmap is not updated. Using the new list of ports, there is a reference count for each port, so it can be saved in software also. For such port, 'struct mlxsw_sp_mdb_entry.ports_count' will not be updated and the port in the list will be marked as 'mrouter'. - Finally, `struct mlxsw_sp_mid.in_hw` is not needed anymore.

Currently, flushing port from all MDB entries is done when the last VLAN is removed. This behavior is inaccurate, as port can be removed while there is another port which uses the same VLAN, in such case, this is not the last port which uses this VLAN and removed, but this port is supposed to be removed from the MDB entries. Flush the port from MDB when it is removed, regardless the state of other ports. Flush only the MDB entries which are relevant for the same FID index. Signed-off-by:

A previous patch added support for init() and fini() for MDB entries. MDB entry can be updated, ports can be added and removed from the entry. Add get() and put() functions, the first one checks if the entry already exists and otherwise initializes the entry. The second removes the entry just in case that there are no more ports in this entry. Use the list of the ports which was added in a previous patch. When the list contains only one port which is not multicast router, and this port is removed, the MDB entry can be removed. Use 'struct mlxsw_sp_mdb_entry.ports_count' to know how many ports use the entry, regardless the use of multicast router ports. When mlxsw_sp_mc_mdb_entry_put() is called with specific port which supposed to be removed, check if the removal will cause a deletion of the entry. If this is the case, call mlxsw_sp_mc_mdb_entry_fini() which first deletes the MDB entry and then releases the PGT entry, to avoid a temporary situation in which the MDB entry points to an empty PGT entry, as otherwise packets will be temporarily dropped instead of being flooded. The new functions will be used in the next patches. Signed-off-by:

The next patches will convert MDB code to use PGT APIs. The change will move the responsibility of allocating MID indexes and writing PGT configurations to hardware to PGT code. As part of this change, most of the MDB code will be changed and improved. As a preparation for the above mentioned change, implement mlxsw_sp_mc_mdb_entry_{init, fini}(). Currently, there is a function __mlxsw_sp_mc_alloc(), which does not only allocate MID. In addition, there is no an equivalent function to free the MID. When mlxsw_sp_port_remove_from_mid() removes the last port, it handles MID removal. Instead, add init() and fini() functions, which use PGT APIs. The differences between the existing and the new functions are as follows: 1. Today MDB code does not update SMID when port is added/removed while multicast is disabled. It maintains a bitmap of ports and once multicast is enabled, it writes the entry to hardware. Instead, using PGT APIs, the entry will be updated also when multicast is disabled, but the mapping between {MAC, FID}->{MID} (is configured using SFD) will be updated according to multicast state. It means that SMID will be updated all the time and disable/enable multicast will impact only SFD configuration. 2. Today the allocation of MID index is done as part of mlxsw_sp_mc_write_mdb_entry(). The fact that the entry will be written in hardware all the time, moves the allocation of the index to be as part of the MDB entry initialization. PGT API is used for the allocation. 3. Today the update of multicast router ports is done as part of mlxsw_sp_mc_write_mdb_entry(). Instead, add functions to add/remove all multicast router ports when entry is first added or removed. When new multicast router port will be added/removed, the dedicated API will be used to add/remove it from the existing entries. 4. A list of ports will be stored per MDB entry instead of the exiting bitmap. The list will contain the multicast router ports and maintain reference counter per port. Add mlxsw_sp_mdb_entry_write() which is almost identical to mlxsw_sp_port_mdb_op(). Use more clear name and align the MID index to bridge model using PGT API. The existing function will be removed in the next patches. Note that PGT APIs configure the firmware using SMID register, like the driver already does today for MDB entries, so PGT APIs can be used also using legacy bridge model. Signed-off-by: -

As part of converting MDB code to use PGT APIs, PGT code stores which ports are mapped to each PGT entry. PGT code is not aware of the type of the port (multicast router or not), as it is not relevant there. To be able to release an MDB entry when the there are no ports which are not multicast routers, the entry should be aware of the state of its ports. Add support for maintaining list of ports per MDB entry. Each port will hold a reference count as multiple MDB entries can use the same hardware MDB entry. It occurs because MDB entries in the Linux bridge are keyed according to their multicast IP, when these entries are notified to device drivers via switchdev, the multicast IP is converted to a multicast MAC. This conversion might cause collisions, for example, ff0e::1 and ff0e:1234::1 are both mapped to the multicast MAC 33:33:00:00:00:01. Multicast router port will take a reference once, and will be marked as 'mrouter', then when port in the list is multicast router and its reference value is one, it means that the entry can be removed in case that there are no other ports which are not multicast routers. For that, maintain a counter per MDB entry to count ports in the list, which were added to the multicast group, and not because they are multicast routers. When this counter is zero, the entry can be removed. Add mlxsw_sp_mdb_entry_port_{get,put}() for regular ports and mlxsw_sp_mdb_entry_mrouter_port_{get,put}() for multicast router ports. Call PGT API to add or remove port from PGT entry when port is first added or removed, according to the reference counting. Signed-off-by:
