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.

2019-11-15net: mscc: ocelot: filter out ocelot SoC specific PCS config from common pathClaudiu Manoil
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: stmmac: Rework TX Coalesce logicJose Abreu
Coalesce logic currently increments the number of packets and sets the IC bit when the coalesced packets have passed a given limit. This does not reflect very well what coalesce was meant for as we can have a large number of packets that are coalesced and then a single one, sent later on that has the IC bit. Rework the logic so that it coalesces only upon a limit of packets and sets the IC bit for large number of packets. Signed-off-by: Jose Abreu <Jose.Abreu@synopsys.com> Signed-off-by: David S.

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.

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.
