Convert to new infra, now the refcounting will be correct, and driver gets port replay of other ports when offloaded port gets removed. Signed-off-by:

Convert to new infra, this driver is very simple. The check of adapter->rawf_cnt in cxgb_udp_tunnel_unset_port() is kept from the old port deletion function but it's dodgy since nothing ever updates that member once its set during init. Also .set_port callback always adds the raw mac filter.. Signed-off-by:

Fairly straightforward conversion - no need to keep track of the use count, and replay when ports get removed, also callbacks can just sleep. Signed-off-by:

Make use of the new udp_tunnel_nic infra. Don't clear the features when VxLAN port is not present to make all drivers behave the same. Driver will now (until we address the problem in the core) leave the RX UDP tunnel feature always on, since this is what most drivers do. Remove the list of VxLAN ports, just program the one core told us to. The driver seem to want to clear the VxLAN ports on close but it doesn't seem to flush the port list properly so it'd get wrong use counts after close/open. Again since it calls its own open handler we need the reset notification hack. v2: - fix kbuild warning Signed-off-by:

Instead of looping though the list of ports just check if the geometry of the packet is correct for VxLAN. HW most likely doesn't care about the exact port, anyway, since only first port is actually offloaded, and this way we won't have to maintain the port list at all. Signed-off-by:

Convert be2net to new udp_tunnel_nic infra. NIC only takes one VxLAN port. Remove the port tracking using a list. The warning in be_work_del_vxlan_port() looked suspicious - like the driver expected ports to be removed in order of addition. be2net unregisters ports when going down and re-registers them (for skyhawk) when coming up, but it never checks if the device is up in the add_port / del_port callbacks. Make it use UDP_TUNNEL_NIC_INFO_OPEN_ONLY. Sadly this driver calls its own open/close functions directly so the udp_tunnel_nic_reset_ntf() workaround is needed. Signed-off-by:

NFP conversion is pretty straightforward. We want to be able to sleep, and only get callbacks when the device is open. NFP did not ask for port replay when ports were removed, now new infra will provide this feature for free. Signed-off-by:

As the cmd IO path has learned to propagate errnos back to its callers, let them deal with errors instead of trying to restore their previous configuration from within the IO error path. Also translate the HW error to a meaningful errno, instead of returning -EIO for all cases (and don't map this to -EOPNOTSUPP later on...). While at it, add a READ_ONCE() / WRITE_ONCE() pair to ensure that the data path always sees a valid isolation mode during reconfiguration. Signed-off-by:

When qeth_set_access_ctrl_online() is called during the device's initialization and discovers that isolation mode isn't supported, don't clear the user's currently configured mode. They intentionally choose to operate the device in this specific mode, and degrading the isolation is not an option. Only adjust the configuration when called via sysfs (ie. fallback = 1), and here follow the common pattern and restore it from prev_isolation. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Mirror to CPU preparations A future patch set will add the ability to trap packets that were dropped due to buffer related reasons (e.g., early drop). Internally this is implemented by mirroring these packets towards the CPU port. This patch set adds the required infrastructure to enable such mirroring. Patches #1-#2 extend two registers needed for above mentioned functionality. Patches #3-#6 gradually add support for setting the mirroring target of a SPAN (mirroring) agent as the CPU port. This is only supported from Spectrum-2 onwards, so an error is returned for Spectrum-1. Patches #7-#8 add the ability to set a policer on a SPAN agent. This is required because unlike regularly trapped packets, a policer cannot be set on the trap group with which the mirroring trap is associated. Patches #9-#12 parse the mirror reason field from the Completion Queue Element (CQE). Unlike other trapped packets, the trap identifier of mirrored packets only indicates that the packet was mirrored, but not why. The reason (e.g., tail drop) is encoded in the mirror reason field. Patch #13 utilizes the mirror reason field in order to lookup the matching Rx listener. This allows us to maintain the abstraction that an Rx listener is mapped to a single trap reason. Without taking the mirror reason into account we would need to register a single Rx listener for all mirrored packets. ==================== Signed-off-by: -
Ido Schimmel authored
The Rx listener abstraction allows the switch driver (e.g., mlxsw_spectrum) to register a function that is called when a packet is received (trapped) for a specific reason. Up until now, the Rx listener lookup was solely based on the trap identifier. However, when a packet is mirrored to the CPU the trap identifier merely indicates that the packet was mirrored, but not why it was mirrored. This makes it impossible for the switch driver to register different Rx listeners for different mirror reasons. Solve this by allowing the switch driver to register a Rx listener with a mirror reason and by extending the Rx listener lookup to take the mirror reason into account. Reviewed-by:

The trap identifier was increased to 10 bits in new versions of the Programmer's Reference Manual (PRM). Increase it accordingly in the Host PacKet Trap (HPKT) register and in the Completion Queue Element (CQE). This is significant for subsequent patches that will introduce trap identifiers which utilize the extended range. Signed-off-by:

When mirroring packets to the CPU port the mirrored packets are trapped to the CPU. However, unlike other traps, it is not possible to set a policer on the associated trap group. Instead, the policer needs to be set on the SPAN agent. Moreover, the policer ID must be within a specified range: From a configurable (even) base ID to this base plus the maximum number of SPAN agents. While the immediate use case is to set the policer on a SPAN agent that mirrors to the CPU port, a policer can be set on any SPAN agent. Therefore, the operation is implemented for all SPAN agent types. Extend the SPAN agent request API to allow passing the desired policer ID that should be bound to the SPAN agent. Return an error for Spectrum-1, as it does not support policer setting on a SPAN agent. Reviewed-by:

Ido Schimmel authored
Currently, the only parameter of a SPAN agent is the netdev which the SPAN agent should mirror to. The next patch will add the ability to request a SPAN agent that mirrors to a specific netdev and has a specific policer ID bound to it. This is required when mirroring packets to the CPU port. Therefore, encapsulate the sole parameter to mlxsw_sp_span_agent_get() in a structure, so that it could later be extended with policer information. Reviewed-by:

The Spectrum-2 and Spectrum-3 ASICs are able to mirror packets towards the CPU. These packets are then trapped like any other packet, but with a special packet trap and additional metadata such as why the packet was mirrored. The ability to mirror packets towards the CPU will be utilized by a subsequent patch set that will mirror packets that were dropped by the ASIC for various buffer-related reasons, such as tail-drop and early-drop. Add mirroring towards the CPU as a new SPAN agent type and re-use the functions that mirror to a physical port where possible. Reviewed-by:
