2019-11-14qtnfmac: send EAPOL frames via control pathSergey Matyukevich
Send EAPOL frames via control path so they can be treated in a different way rather than normal data frames. In this case EAPOLs are sent with higher priority and with disabled aggregation and encryption. Besides, all devices benefit from sending EAPOL frames via high priority path, so move the functionality from chip specific to common code.

2019-11-13net: atlantic: Signedness bug in aq_vec_isr_legacy()Dan Carpenter
irqreturn_t type is an enum and in this context it's unsigned, so "err" can't be irqreturn_t or it breaks the error handling. In fact the "err" variable is only used to store integers (never irqreturn_t) so it should be declared as int. I removed the initialization because it's not required. Using a bogus initializer turns off GCC's uninitialized variable warnings. Secondly, there is a GCC warning about unused assignments and we would like to enable that feature eventually so we have been trying to remove these unnecessary initializers.

2019-11-13net/mlx5: Read num_vfs before disabling SR-IOVParav Pandit
mlx5_device_disable_sriov() currently reads num_vfs from the PCI core. However when mlx5_device_disable_sriov() is executed, SR-IOV is already disabled at the PCI level. Due to this disable_hca() cleanup is not done during SR-IOV disable flow. mlx5_sriov_disable() pci_enable_sriov() mlx5_device_disable_sriov() <- num_vfs is zero here. When SR-IOV enablement fails during mlx5_sriov_enable(), HCA's are left in enabled stage because mlx5_device_disable_sriov() relies on num_vfs from PCI core. mlx5_sriov_enable() mlx5_device_enable_sriov() pci_enable_sriov() <- Fails Hence, to overcome above issues, (a) Read num_vfs before disabling SR-IOV and use it.

2019-11-13net/mlx5: Add new chain for netfilter flow table offloadPaul Blakey
Netfilter tables (nftables) implements a software datapath that comes after tc ingress datapath. The datapath supports offloading such rules via the flow table offload API. This API is currently only used by NFT and it doesn't provide the global priority in regards to tc offload, so we assume offloading such rules must come after tc. It does provide a flow table priority parameter, so we need to provide some supported priority range. For that, split fastpath prio to two, flow table offload and tc offload, with one dedicated priority chain for flow table offload. Next patch will re-use the multi chain API to access this chain by allowing access to this chain by the fdb_sub_namespace.

2019-11-13net/mlx5: Accumulate levels for chains prio namespacesPaul Blakey
Tc chains are implemented by creating a chained prio steering type, and inside it there is a namespace for each chain (FDB_TC_MAX_CHAINS). Each of those has a list of priorities. Currently, all namespaces in a prio start at the parent prio level. But since we can jump from chain (namespace) to another chain in the same prio, we need the levels for higher chains to be higher as well. So we created unused prios to account for levels in previous namespaces. Fix that by accumulating the namespaces levels if we are inside a chained type prio, and removing the unused prios.

Similar to VLAN and similar drivers, we can forward get_link_ksettings to the lower dev if we have one to get meaningful speed/duplex data. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-11-12net: dsa: Prevent usage of NET_DSA_TAG_8021Q as tagging protocolFlorian Fainelli
It is possible for a switch driver to use NET_DSA_TAG_8021Q as a valid DSA tagging protocol since it registers itself as such, unfortunately since there are not xmit or rcv functions provided, the lack of a xmit() function will lead to a NPD in dsa_slave_xmit() to start with. net/dsa/tag_8021q.c is only comprised of a set of helper functions at the moment, but is not a fully autonomous or functional tagging "driver" (though it could become later on). We do not have any users of NET_DSA_TAG_8021Q so now is a good time to make sure there are not issues being encountered by making this file strictly a place holder for helper functions.

2019-11-12tipc: update mon's self addr when node addr generatedHoang Le
In commit 25b0b9c4e835 ("tipc: handle collisions of 32-bit node address hash values"), the 32-bit node address only generated after one second trial period expired. However the self's addr in struct tipc_monitor do not update according to node address generated. This lead to it is always zero as initial value. As result, sorting algorithm using this value does not work as expected, neither neighbor monitoring framework. In this commit, we add a fix to update self's addr when 32-bit node address generated.
