2019-11-04net: of_get_phy_mode: Change API to solve int/unit warningsAndrew Lunn
Before this change of_get_phy_mode() returned an enum, phy_interface_t. On error, -ENODEV etc, is returned. If the result of the function is stored in a variable of type phy_interface_t, and the compiler has decided to represent this as an unsigned int, comparision with -ENODEV etc, is a signed vs unsigned comparision. Fix this problem by changing the API. Make the function return an error, or 0 on success, and pass a pointer, of type phy_interface_t, where the phy mode should be stored. v2: Return with *interface set to PHY_INTERFACE_MODE_NA on error.

2019-11-01net/mlx5: Support lockless FTE read lookupsParav Pandit
During connection tracking offloads with high number of connections, (40K connections per second), flow table group lock contention is observed. To improve the performance by reducing lock contention, lockless FTE read lookup is performed as described below. Each flow table entry is refcounted. Flow table entry is removed when refcount drops to zero. rhash table allows rcu protected lookup. Each hash table entry insertion and removal is write lock protected. Hence, it is possible to perform lockless lookup in rhash table using following scheme. (a) Guard FTE entry lookup per group using rcu read lock. (b) Before freeing the FTE entry, wait for all readers to finish accessing the FTE. Below example of one reader and write in parallel racing, shows protection in effect with rcu lock. lookup_fte_locked() rcu_read_lock(); search_hash_table() existing_flow_group_write_lock(); tree_put_node(fte) drop_ref_cnt(fte) del_sw_fte(fte) del_hash_table_entry(); call_rcu(); existing_flow_group_write_unlock(); get_ref_cnt(fte) fails rcu_read_unlock(); rcu grace period(); [..] kmem_cache_free(fte); Signed-off-by: Parav Pandit <parav@mellanox.com> Reviewed-by: Mark Bloch <markb@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

Lyude Paul fixes an issue where a fatal read error occurs when the device is unplugged from the machine. So change the read error into a warn while the device is still present. Manfred Rudigier found that the i350 device was not apart of the "Media Auto Sense" feature, yet the device supports it. So add the missing i350 device to the check and fix an issue where the media auto sense would flip/flop when no cable was connected to the port causing spurious kernel log messages. I fixed an issue where the fix to resolve receive buffer starvation was applied in more than one place in the driver, one being the incorrect location in the i40e driver. Wenwen Wang fixes a potential memory leak in e1000 where allocated memory is not properly cleaned up in one of the error paths.

2019-11-01net/mlx5: E-switch, Enable metadata on own vportParav Pandit
Currently on ECPF, metadata is enabled on the ECPF vport = 0xfffe (manager vport). Metadata when supported, must be enabled on own vport which is used to pass metadata to vport of NIC Rx Flow Table. Due to this error, traffic tagged by ingress ACL is not processed correctly at NIC rx flow table level which is supposed to work on metadata tag. Hence, instead of working on eswitch manager vport, always working on eswitch own vport regardless of PF or ECPF. Given that mlx5_eswitch_query/modify_esw_vport_context() is used to access other vport in legacy mode and own vport settings in switchdev mode, extend low level API to explicitly specify other_vport.

2019-11-01i40e: Fix receive buffer starvation for AF_XDPJeff Kirsher
Magnus's fix to resolve a potential receive buffer starvation for AF_XDP got applied to both the i40e_xsk_umem_enable/disable() functions, when it should have only been applied to the "enable". So clean up the undesired code in the disable function.

2019-11-01igb: Fix constant media auto sense switching when no cable is connectedManfred Rudigier
At least on the i350 there is an annoying behavior that is maybe also present on 82580 devices, but was probably not noticed yet as MAS is not widely used. If no cable is connected on both fiber/copper ports the media auto sense code will constantly swap between them as part of the watchdog task and produce many unnecessary kernel log messages. The swap code responsible for this behavior (switching to fiber) should not be executed if the current media type is copper and there is no signal detected on the fiber port. In this case we can safely wait until the AUTOSENSE_EN bit is cleared.
