2023-07-28sfc: Remove struct efx_special_bufferMartin Habets
The attributes index and entries are no longer needed, so use struct efx_buffer instead. next_buffer_table was also Siena specific. Removed some checkpatch warnings.

2020-09-11sfc: de-indirect TSO handlingEdward Cree
Remove the tx_queue->handle_tso function pointer, and just use tx_queue->tso_version to decide which function to call, thus removing an indirect call from the fast path. Instead of passing a tso_v2 flag to efx_mcdi_tx_init(), set the desired tx_queue->tso_version before calling it. In efx_mcdi_tx_init(), report back failure to obtain a TSOv2 context by setting tx_queue->tso_version to 0, which will cause the TX path to use the GSO-based fallback.

2020-09-11sfc: create inner-csum queues on EF10 if supportedEdward Cree
If the MC reports the VXLAN_NVGRE datapath capability, then these queues can be used for checksum offload of encapsulated packets. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-09-11sfc: define inner/outer csum offload TXQ typesEdward Cree
Nothing yet creates inner csum TXQs; just change all references to EFX_TXQ_TYPE_OFFLOAD to the new EFX_TXQ_TYPE_OUTER_CSUM. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-09-11sfc: decouple TXQ type from labelEdward Cree
Make it possible to have an arbitrary mapping from types to labels, because when we add inner-csum-offload TXQs there will no longer be a convenient nesting hierarchy of NIC types (EF10 will have inner-csum TXQs, while Siena will have HIGHPRI). Correct a misleading comment on efx_hard_start_xmit(). Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-07-02sfc: assign TXQs without gapsEdward Cree
Since we only allocate VIs for the number of TXQs we actually need, we cannot naively use "channel * TXQ_TYPES + txq" for the TXQ number, as this has gaps (when efx->tx_queues_per_channel < EFX_TXQ_TYPES) and thus overruns the driver's VI allocations, causing the firmware to reject the MC_CMD_INIT_TXQ based on INSTANCE. Thus, we distinguish INSTANCE (stored in tx_queue->queue) from LABEL (tx_queue->label); the former is allocated starting from 0 in efx_set_channels(), while the latter is simply the txq type (index in channel->tx_queue array). To simplify things, rather than changing tx_queues_per_channel after setting up TXQs, make Siena always probe its HIGHPRI queues at start of day, rather than deferring it until tc mqprio enables them.

2020-05-11sfc: move vport_id to struct efx_nicEdward Cree
