Update ibmvnic reset infrastructure to include a new reset option that will allow changing of tunable parameters. There currently is no way to request different capabilities from the vnic server on the fly so this patch achieves this by resetting the driver and attempting to log in with the requested changes. If the reset operation fails, the old values of the tunable parameters are stored in the "fallback" struct and we attempt to login with the fallback values. Signed-off-by:

Subash Abhinov Kasiviswanathan says: ==================== net: qualcomm: rmnet: Add 64 bit stats and GRO This series adds support for 64 bit per cpu stats and GRO Patches 1-2 are cleanups of return code and a redundant condition Patch 3 adds support for 64 bit per cpu stats Patch 4 adds support for GRO using GRO cells v1->v2: Since gro_cells_init() could potentially fail, move it from device setup to ndo_init() as mentioned by Eric. ==================== Signed-off-by: -

Since packet is always consumed by rmnet_rx_handler(), we always return RX_HANDLER_CONSUMED. There is no need to pass on this value through multiple functions. Signed-off-by:

Michael Chan says: ==================== bnxt_en: Updates for net-next.

This patch adds IPv4 vxlan encap/decap action support to TC-flower offload. For vxlan encap, the driver maintains a tunnel encap hash-table. When a new flow with a tunnel encap action arrives, this table is looked up; if an encap entry exists, it uses the already programmed encap_record_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new encap node is added and the L2 header fields are queried via a route lookup. hwrm_cfa_encap_record_alloc cmd is used to create a new encap record and the encap_record_handle is used as the tunnel_handle while adding the flow. For vxlan decap, the driver maintains a tunnel decap hash-table. When a new flow with a tunnel decap action arrives, this table is looked up; if a decap entry exists, it uses the already programmed decap_filter_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new decap node is added and a decap_filter_handle is alloc'd via the hwrm_cfa_decap_filter_alloc cmd. This handle is used as the tunnel_handle while adding the flow. The code to issue the HWRM FW cmds is introduced in a follow-up patch. Signed-off-by:

The mapping of the ethtool coalescing parameters to hardware parameters is now done in bnxt_hwrm_set_coal_params(). The same function can handle both RX and TX settings. The code is now more clear. Some adjustments have been made to get better hardware settings. The coal_frames setting is now accurately set in hardware. The max_timer is set to coal_ticks value. Signed-off-by:

Michael Chan authored
The current IRQ coalescing logic is a little messy. The ethtool parameters are mapped to hardware parameters in a way that is difficult to understand. The first step is to better organize the parameters by adding the new structure bnxt_coal. The structure is used by both the RX and TX sets of coalescing parameters. Adjust the default coal_ticks to 14 us and 28 us for RX and TX. Signed-off-by:

The current code retrieves the firmware package version from firmware everytime ethtool -i is run. There is no reason to do that as the firmware will not change while the driver is loaded. Get the version once at init time. Also, display the full 4-part firmware version string and remove the less useful interface spec version. Signed-off-by:

Vivien Didelot says: ==================== net: dsa: define port types The DSA code currently has 3 bitmaps in the dsa_switch structure: cpu_port_mask, dsa_port_mask and enabled_port_mask. They are used to store the type of each switch port. This dates back from when DSA didn't have a dsa_port structure to hold port-specific data. The dsa_switch structure is mainly used to communicate with DSA drivers and must not contain such static data parsed from DTS or pdata, which belongs the DSA core structures, such as dsa_switch_tree and dsa_port. Also the enabled_port_mask is misleading, often misinterpreted as the complement of disabled ports (thus including DSA and CPU ports), while in fact it only masks the user ports. A port can be of 3 types when it is not unused: "cpu" (interfacing with a master device), "dsa" (interconnecting with another "dsa" port from another switch chip), or "user" (user-facing port.) This patchset first fixes the usage of DSA port type helpers, then defines the DSA_PORT_TYPE_UNUSED, DSA_PORT_TYPE_CPU, DSA_PORT_TYPE_DSA, and DSA_PORT_TYPE_USER port types, and finally removes the misleading port bitmaps. ==================== Signed-off-by: -

Now that DSA core provides port types, there is no need to keep this information at the switch level. This is a static information that is part of a DSA core dsa_port structure. Remove them. Signed-off-by:

Now that DSA exposes an enumerated type for the ports, we can use them directly instead of checking bitmaps, which is more consistent. Signed-off-by:
-
Vivien Didelot authored
Introduce an enumerated type for ports, which will be way more explicit to identify a port type instead of digging into switch port masks. A port can be of type CPU, DSA, user, or unused by default. This is a static parsed information that cannot be changed at runtime. Signed-off-by:
-
Vivien Didelot authored
Introduce a dsa_user_ports() helper to return the ds->enabled_port_mask mask which is more explicit. This will also minimize diffs when touching this internal mask. Signed-off-by:
-
Vivien Didelot authored
Most of the DSA code still check ds->enabled_port_mask directly to inspect a given port type instead of using the provided dsa_is_user_port helper. Change this. Signed-off-by:
-
Vivien Didelot authored
This patch renames dsa_is_normal_port to dsa_is_user_port because "user" is the correct term in the DSA terminology, not "normal". Signed-off-by:
-
Vivien Didelot authored
In order to know if a port is of type user, dsa_is_normal_port checks that the given port is not of type DSA nor CPU. This is not enough because a port can be unused. Without the previous fix, this caused the unused mv88e6xxx ports to be configured in normal mode. The ds->enabled_port_mask reports the user ports, so check this instead. Signed-off-by:
-
Vivien Didelot authored
The unused ports are currently configured in normal mode. This does not prevent the switch from being functional, but it is unnecessary. Skip unused ports. Signed-off-by:
-
Vivien Didelot authored
As the comment above the chunk states, the b53 driver attempts to disable the unused ports. But using ds->enabled_port_mask is misleading, because this mask reports in fact the user ports. To avoid confusion and fix this, this patch introduces an explicit dsa_is_unused_port helper which ensures the corresponding bit is not masked in any of the switch port masks. Signed-off-by:
