2019-10-31mlxsw: spectrum: Distinguish between unsplittable and split portJiri Pirko
Currently when user does split, he is not able to distinguish if the port cannot be split because it is already split, or because it cannot be split at all. Add another check for split flag to distinguish this. Also add check forbidding split when maximal width is 1.

2019-10-30mlxsw: core: Unpublish devlink parameters during reloadJiri Pirko
The devlink parameter "acl_region_rehash_interval" is a runtime parameter whose value is stored in a dynamically allocated memory. While reloading the driver, this memory is freed and then allocated again. A use-after-free might happen if during this time frame someone tries to retrieve its value. Since commit 070c63f20f6c ("net: devlink: allow to change namespaces during reload") the use-after-free can be reliably triggered when reloading the driver into a namespace, as after freeing the memory (via reload_down() callback) all the parameters are notified. Fix this by unpublishing and then re-publishing the parameters during reload.

2019-10-30qed: Optimize execution time for nvm attributes configuration.Sudarsana Reddy Kalluru
Current implementation for nvm_attr configuration instructs the management FW to load/unload the nvm-cfg image for each user-provided attribute in the input file. This consumes lot of cycles even for few tens of attributes. This patch updates the implementation to perform load/commit of the config for every 50 attributes. After loading the nvm-image, MFW expects that config should be committed in a predefined timer value (5 sec), hence it's not possible to write large number of attributes in a single load/commit window. Hence performing the commits in chunks. Fixes: 0dabbe1bb3a4 ("qed: Add driver API for flashing the config attributes.")

2019-10-29e1000e: Drop unnecessary __E1000_DOWN bit twiddlingAlexander Duyck
Since we no longer check for __E1000_DOWN in e1000e_close we can drop the spot where we were restoring the bit. This saves us a bit of unnecessary complexity.

2019-10-29e1000e: Use rtnl_lock to prevent race conditions between net and pci/pmAlexander Duyck
This patch is meant to address possible race conditions that can exist between network configuration and power management. A similar issue was fixed for igb in commit 9474933caf21 ("igb: close/suspend race in netif_device_detach"). In addition it consolidates the code so that the PCI error handling code will essentially perform the power management freeze on the device prior to attempting a reset, and will thaw the device afterwards if that is what it is planning to do. Otherwise when we call close on the interface it should see it is detached and not attempt to call the logic to down the interface and free the IRQs again. From what I can tell the check that was adding the check for __E1000_DOWN in e1000e_close was added when runtime power management was added. However it should not be relevant for us as we perform a call to pm_runtime_get_sync before we call e1000_down/free_irq so it should always be back up before we call into this anyway.
