Defer ringing the Tx doorbell if skb->xmit_more is set unless the Tx queue is full or stopped. To keep latency low, use a deferral limit of 8 packets. We chose 8 because Octeon can fetch at most 8 packets in a single PCI read, and our tests show that 8 results in low latency. Signed-off-by:

For all non-fatal reset conditions, the hypervisor will send a failover when we attempt to initialize the crq and the vnic client is expected to handle that failover instead of the existing non-fatal reset. To handle this, we need to return from init with a return code that indicates that we have hit this case. Signed-off-by:

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:

Sathya Perla authored
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.

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: -
Vivien Didelot authored
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:
