2019-01-30net: hns3: keep flow director state unchanged when resetJian Shen2-5/+7
In orginal codes, driver always enables flow director when intializing. When user disable flow director with command ethtool -K, the flow director will be enabled again after resetting. This patch fixes it by only enabling it when first initialzing.

2019-01-30net: hns3: fix netif_napi_del() not do problem when unloadingHuazhong Tan1-20/+7
When the driver is unloading, if a global reset occurs, unmap_ring_from_vector() in the hns3_nic_uninit_vector_data() will fail, and hns3_nic_uninit_vector_data() just return. There may be some netif_napi_del() not be done. Since hardware will unmap all ring while resetting, so hns3_nic_uninit_vector_data() should ignore this error, and do the rest uninitialization.

2019-01-30net: dsa: mt7530: support the 7530 switch on the Mediatek MT7621 SoCGreg Ungerer2-39/+66
The MediaTek MT7621 SoC device contains a 7530 switch, and the existing linux kernel 7530 DSA switch driver can be used with it. The bulk of the changes required stem from the 7621 having different regulator and pad setup. The existing setup of these in the 7530 driver appears to be very specific to its implemtation in the Mediatek 7623 SoC. (Not entirely surprising given the 7623 is a quad core ARM based SoC, and the 7621 is a dual core, dual thread MIPS based SoC). Create a new devicetree type, "mediatek,mt7621", to support the 7530 switch in the 7621 SoC. There appears to be no usable ID register to distinguish it from a 7530 in other hardware at runtime. This is used to carry out the appropriate configuration and setup.

This patch is to add 3 constants SCTP_FUTURE_ASSOC, SCTP_CURRENT_ASSOC and SCTP_ALL_ASSOC for reserved assoc_ids, as defined in rfc6458#section-7.2. And add the process for them when doing lookup and inserting in sctp_id2assoc and sctp_assoc_set_id. Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S.

2019-01-29bnxt_en: Add bnxt_en initial port params table and register itVasundhara Volam3-1/+44
Register devlink_port with devlink and create initial port params table for bnxt_en. The table consists of a generic parameter: wake_on_lan: Enables Wake on Lan for this port when magic packet is received with this port's MAC address using ACPI pattern. If enabled, the controller asserts a wake pin upon reception of WoL packet. ACPI (Advanced Configuration and Power Interface) is an industry specification for the efficient handling of power consumption in desktop and mobile computers. v2->v3: - Modify bnxt_dl_wol_validate(), to throw error message when user gives value other than DEVLINK_PARAM_WAKE_MAGIC ot to disable WOL. - Use netdev_err() instead of netdev_warn(), when devlink_port_register() and devlink_port_params_register() returns error. Also, don't log rc in this message. Cc: Michael Chan <michael.chan@broadcom.com> Signed-off-by: Vasundhara Volam <vasundhara-v.volam@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-01-29devlink: Add a generic wake_on_lan port parameterVasundhara Volam2-0/+13
wake_on_lan - Enables Wake on Lan for this port. If enabled, the controller asserts a wake pin based on the WOL type. v2->v3: - Define only WOL types used now and define them as bitfield, so that mutliple WOL types can be enabled upon power on. - Modify "wake-on-lan" name to "wake_on_lan" to be symmetric with previous definitions. - Rename DEVLINK_PARAM_WOL_XXX to DEVLINK_PARAM_WAKE_XXX to be symmetrical with ethtool WOL definitions.

Add notification call for devlink port param set, register and unregister functions. Add devlink_port_param_value_changed() function to enable the driver notify devlink on value change.
