2019-11-15net: mscc: ocelot: export a constant for the tag length in bytesVladimir Oltean
This constant will be used in a future patch to increase the MTU on NPI ports, and will also be used in the tagger driver for Felix. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-11-15net: mscc: ocelot: create a helper for changing the port MTUVladimir Oltean
Since in an NPI/DSA setup, not all ports will have the same MTU, we need to make sure the watermarks for pause frames and/or tail dropping logic that existed in the driver is still coherent for the new MTU values. We need to do this because the NPI (aka external CPU) port needs an increased MTU for the DSA tag. This will be done in a future patch.

2019-11-15net: mscc: ocelot: move invariant configs out of adjust_linkVladimir Oltean
It doesn't make sense to rewrite all these registers every time the PHY library notifies us about a link state change. In a future patch we will customize the MTU for the CPU port, and since the MTU was previously configured from adjust_link, if we don't make this change, its value would have got overridden.

The adjust_link routine should be generic enough to be (re)used by any SoC that integrates a switch core compatible with the Ocelot core switch driver. Currently all configurations are generic except for the PCS settings that are SoC specific. Move these out to the Ocelot SoC/board instance.

2019-11-15net/smc: immediate termination for SMCD link groupsUrsula Braun
SMCD link group termination is called when peer signals its shutdown of its corresponding link group. For regular shutdowns no connections exist anymore. For abnormal shutdowns connections must be killed and their DMBs must be unregistered immediately. That means the SMCR method to delay the link group freeing several seconds does not fit. This patch adds immediate termination of a link group and its SMCD connections and makes sure all SMCD link group related cleanup steps are finished.

2019-11-15mlxsw: spectrum_router: Allocate discard adjacency entry when neededIdo Schimmel
Commit 0c3cbbf96def ("mlxsw: Add specific trap for packets routed via invalid nexthops") allocated an adjacency entry during driver initialization whose purpose is to discard packets hitting the route pointing to it. These adjacency entries are allocated from a resource called KVD linear (KVDL). There are situations in which the user can decide to set the size of this resource (via devlink-resource) to 0, in which case the driver will not be able to load. Therefore, instead of pre-allocating this adjacency entry, simply allocate it only when needed. A variable indicating the validity of the entry is added and is used to ensure it is only allocated and written once and that it is freed after all the routes were flushed.

This is OK as this configuration is not supported, but it prevents us from testing bad flows involving the enslavement of VXLAN devices with a physical device to a bridge, regardless if the physical device is an mlxsw netdev or not.

2019-11-15afs: Fix race in commit bulk status fetchDavid Howells
When a lookup is done, the afs filesystem will perform a bulk status-fetch operation on the requested vnode (file) plus the next 49 other vnodes from the directory list (in AFS, directory contents are downloaded as blobs and parsed locally). When the results are received, it will speculatively populate the inode cache from the extra data. However, if the lookup races with another lookup on the same directory, but for a different file - one that's in the 49 extra fetches, then if the bulk status-fetch operation finishes first, it will try and update the inode from the other lookup. If this other inode is still in the throes of being created, however, this will cause an assertion failure in afs_apply_status(): BUG_ON(test_bit(AFS_VNODE_UNSET, &vnode->flags)); on or about fs/afs/inode.c:175 because it expects data to be there already that it can compare to. Fix this by skipping the update if the inode is being created as the creator will presumably set up the inode with the same information.

The code now compiles without ACPI, but there's a warning since iwl_mvm_get_ppag_table() isn't used, and iwl_mvm_ppag_init() must not unconditionally fail but return success instead.

2019-11-15iwlwifi: remove IWL_DEVICE_22560/IWL_DEVICE_FAMILY_22560Johannes Berg
This is dead code, nothing uses the IWL_DEVICE_22560 macro and thus nothing every uses IWL_DEVICE_FAMILY_22560. Remove it all. While at it, remove some code and definitions used only in this case, and clean up some comments/names that still refer to it.

2019-11-15iwlwifi: mvm: don't skip mgmt tid when flushing all tidsHaim Dreyfuss
There are various of flows which require tids flushing (disconnection, suspend, etc...). Currently, when the driver instructs the FW to flush he masks all the data tids(0-7). However, the driver doesn't set the management tid (#15) which cause the FW not to flush it. When the FW tries to remove the mgmt queue he throws an assert since it is not an empty queue. instead of just set only the data tids set everything and let the FW ignore the invalid tids.
