2021-03-31ice: Refactor ice_set/get_rss into LUT and key specific functionsBrett Creeley
Currently ice_set/get_rss are used to set/get the RSS LUT and/or RSS key. However nearly everywhere these functions are called only the LUT or key are set/get. Also, making this change reduces how many things ice_set/get_rss are doing. Fix this by adding ice_set/get_rss_lut and ice_set/get_rss_key functions. Also, consolidate all calls for setting/getting the RSS LUT and RSS Key to use ice_set/get_rss_lut() and ice_set/get_rss_key().

2021-03-31ice: Refactor get/set RSS LUT to use struct parameterBrett Creeley
Update ice_aq_get_rss_lut() and ice_aq_set_rss_lut() to take a new structure ice_aq_get_set_rss_params instead of passing individual parameters. This is done for 2 reasons: 1. Reduce the number of parameters passed to the functions. 2. Reduce the amount of change required if the arguments ever need to be updated in the future. Also, reduce duplicate code that was checking for an invalid vsi_handle and lut parameter by moving the checks to the lower level __ice_aq_get_set_rss_lut().

2021-03-31ice: Change ice_vsi_setup_q_map() to not depend on RSSBrett Creeley
Currently, ice_vsi_setup_q_map() depends on the VSI's rss_size. However, the Rx Queue Mapping section of the VSI context has no dependency on RSS. Instead, limit the maximum number of Rx queues per TC based on the Rx Queue mapping section of the VSI context, which currently allows for up to 256 Rx queues per TC.

2021-03-31ice: handle increasing Tx or Rx ring sizesPaul M Stillwell Jr
There is an issue when the Tx or Rx ring size increases using 'ethtool -L ...' where the new rings don't get the correct ITR values because when we rebuild the VSI we don't know that some of the rings may be new. Fix this by looking at the original number of rings and determining if the rings in ice_vsi_rebuild_set_coalesce() were not present in the original rings received in ice_vsi_rebuild_get_coalesce(). Also change the code to return an error if we can't allocate memory for the coalesce data in ice_vsi_rebuild().

2021-03-31ice: Delay netdev registrationAnirudh Venkataramanan
Once a netdev is registered, the corresponding network interface can be immediately used by userspace utilities (like say NetworkManager). This can be problematic if the driver technically isn't fully up yet. Move netdev registration to the end of probe, as by this time the driver data structures and device will be initialized as expected. However, delaying netdev registration causes a failure in the aRFS flow where netdev->reg_state == NETREG_REGISTERED condition is checked. It's not clear why this check was added to begin with, so remove it. Local testing didn't indicate any issues with this change. The state bit check in ice_open was put in as a stop-gap measure to prevent a premature interface up operation. This is no longer needed, so remove it.

2021-03-30mlxsw: spectrum_router: Only perform atomic nexthop bucket replacement when ↵Ido Schimmel
requested When cleared, the 'force' parameter in nexthop bucket replacement notifications indicates that a driver should try to perform an atomic replacement. Meaning, only update the contents of the bucket if it is inactive. Since mlxsw only queries buckets' activity once every second, there is no point in trying an atomic replacement if the idle timer interval is smaller than 1 second. Currently, mlxsw ignores the original value of 'force' and will always try an atomic replacement if the idle timer is not smaller than 1 second. Fix this by taking the original value of 'force' into account and never promoting a non-atomic replacement to an atomic one.

2021-03-30can: c_can: add support to 64 message objectsDario Binacchi
D_CAN controller supports 16, 32, 64 or 128 message objects, comparing to 32 on C_CAN. AM335x/AM437x Sitara processors and DRA7 SOC all instantiate a D_CAN controller with 64 message objects, as described in the "DCAN features" subsection of the CAN chapter of their technical reference manuals. The driver policy has been kept unchanged, and as in the previous version, the first half of the message objects is used for reception and the second for transmission. The I/O load is increased only in the case of 64 message objects, keeping it unchanged in the case of 32. Two 32-bit read accesses are in fact required, which however remained at 16-bit for configurations with 32 message objects.

As pointed by commit c0a9f4d396c9 ("can: c_can: Reduce register access") the "driver casts the 16 message objects in stone, which is completely braindead as contemporary hardware has up to 128 message objects". The patch prepares the module to extend the number of message objects beyond the 32 currently managed. This was achieved by transforming the constants used to manage RX/TX messages into variables without changing the driver policy.
