2020-09-25devlink: convert flash_update to use params structureJacob Keller1-3/+2
The devlink core recently gained support for checking whether the driver supports a flash_update parameter, via `supported_flash_update_params`. However, parameters are specified as function arguments. Adding a new parameter still requires modifying the signature of the .flash_update callback in all drivers. Convert the .flash_update function to take a new `struct devlink_flash_update_params` instead. By using this structure, and the `supported_flash_update_params` bit field, a new parameter to flash_update can be added without requiring modification to existing drivers. As before, all parameters except file_name will require driver opt-in. Because file_name is a necessary field to for the flash_update to make sense, no "SUPPORTED" bitflag is provided and it is always considered valid. All future additional parameters will require a new bit in the supported_flash_update_params bitfield.

2020-09-25devlink: check flash_update parameter support in net coreJacob Keller1-3/+0
When implementing .flash_update, drivers which do not support per-component update are manually checking the component parameter to verify that it is NULL. Without this check, the driver might accept an update request with a component specified even though it will not honor such a request. Instead of having each driver check this, move the logic into net/core/devlink.c, and use a new `supported_flash_update_params` field in the devlink_ops. Drivers which will support per-component update must now specify this by setting DEVLINK_SUPPORT_FLASH_UPDATE_COMPONENT in the supported_flash_update_params in their devlink_ops. This helps ensure that drivers do not forget to check for a NULL component if they do not support per-component update. This also enables a slightly better error message by enabling the core stack to set the netlink bad attribute message to indicate precisely the unsupported attribute in the message. Going forward, any new additional parameter to flash update will require a bit in the supported_flash_update_params bitfield.

When calling hinic_close in hinic_set_channels, all queues are stopped after netif_tx_disable, but some queue may be rewaken in free_tx_poll by mistake while drv is handling tx irq. If one queue is rewaken core may call hinic_xmit_frame to send pkt after netif_tx_disable within a short time which may results in accessing memory that has been already freed in hinic_close. So we call napi_disable before netif_tx_disable in hinic_close to fix this bug.
