Adds functions to allocate and free vswitches and vports; vadaptors are automatically allocated and freed when TX/RX queues are initialised and finalised. This vswitching structure is only created if the firmware supports it, so a check that full-featured firmware is running is performed first. If the MC resets, the vswitching infrastructure will need to be recreated, so mark the "must_probe_vswitching" flag when an MC reboot is detected. Don't try to create a vswitch if vf-count=0 This allocation of vswitches and vports does not currently support configuring VLAN tags, but that can be added in a future change.

sfc: Own header for nic-specific sriov functions, single instance of netdev_ops and sriov removed from Falcon code By putting all the efx_{siena,ef10}_sriov_* declarations in {siena,ef10}_sriov.h, ensure they cannot be called from nic-generic code. Also fixes up an instance of this, where mcdi.c was calling efx_siena_sriov_flr. The single instance of netdev_ops should call general high level functions that can then call something adapter specific in efx_nic_type. We should only do adapter specialisation via efx_nic_type. Removal of sriov functionality from the Falcon code means that tests are needed for the presence of some callbacks. Signed-off-by: NShradha Shah <sshah@solarflare.com> Signed-off-by: NDavid S.

When an MCDI command times out (whether or not we find it completed when we poll), call efx_mcdi_abandon(), which tells all subsequent MCDI calls to fail-fast, and queues up an FLR. Because an FLR doesn't lead to receiving any reboot even from the MC (unlike most other types of reset), we have to call efx_ef10_reset_mc_allocations. In efx_start_all(), if a reset (of any kind) is pending, we bail out. Without this, attempts to reconfigure (e.g. change mtu) can cause driver/mc state inconsistency if the first MCDI call triggers an FLR. For similar reasons, on EF10, in efx_reset_down(method=RESET_TYPE_MCDI_TIMEOUT), set the number of active queues to zero before calling efx_stop_all(). And, on farch, in efx_reset_up(method=RESET_TYPE_MCDI_TIMEOUT), set active_queues and flushes pending & outstanding to zero. efx_mcdi_mode_{poll,event}() should not take us out of fail-fast mode. Instead, this is done by efx_mcdi_reset() after the FLR completes. The new FLR reset_type RESET_TYPE_MCDI_TIMEOUT doesn't really fit into the hierarchy of reset 'scopes' whereby efx_reset() decides some resets subsume others. Thus, it uses separate logic. Also, fixed up some inconsistency around RESET_TYPE_MC_BIST, which was in the wrong place in that hierarchy. Signed-off-by: NShradha Shah <sshah@solarflare.com> Signed-off-by: NDavid S.

We need a dedicated channel on Siena to ensure we can match up the separate RX and timestamp events for each PTP packet. We won't do this for EF10 as timestamps are delivered inline.

We don't directly control RX ingress on Siena or any later controllers, and so we cannot prevent packets from entering the RX datapath while the RX queues are not set up. This results in the hardware incrementing RX_NODESC_DROP_CNT, but it's not an error and we should not include it in error stats. When bringing an interface up or down, pull (or wait for) stats and count the number of packets that were dropped while the interface was down. Subtract this from the reported RX dropped count.

Various hardware statistics that are available for Siena are unavailable or meaningless for Falcon. Huntington adds further to the NIC-type-specific statistics, as it has different MAC blocks from Falcon/Siena. All NIC types still provide most statistics by DMA, and use little-endian byte order. Therefore: 1. Add some general utility functions for reporting hardware statistics, efx_nic_describe_stats() and efx_nic_update_stats(). 2. Add an efx_nic_type::describe_stats operation to get the number and names of statistics, implemented using efx_nic_describe_stats() 3. Change efx_nic_type::update_stats to store the core statistics (struct rtnl_link_stats64) or full statistics (array of u64) in a caller-provided buffer. Use efx_nic_update_stats() to aid in the implementation. 4. Rename struct efx_ethtool_stat to struct efx_sw_stat_desc and EFX_ETHTOOL_NUM_STATS to EFX_ETHTOOL_SW_STAT_COUNT. 5. Remove efx_nic::mac_stats and struct efx_mac_stats. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

Merge the per-NIC-type MTD probe selection and struct efx_mtd_ops into struct efx_nic_type. Move the implementations into the appropriate source files. Several NVRAM functions are now only called from MTD operations which are now implemented in the same file (falcon.c or mcdi.c). There is no need for them to be extern, or to be defined at all if CONFIG_SFC_MTD is not enabled, so move them into the #ifdef CONFIG_SFC_MTD sections in those files. Most of the SPI-related definitions are also only used in falcon.c, so move them there. Put the remainder of spi.h into nic.h (which previously included it).

On Falcon we implement MAC filtering requested by the stack using the MAC wrapper's single unicast filter and multicast hash filter. Siena is very similar, though MAC configuration is mediated by the MC. Since MCDI operations may sleep, reconfiguration is deferred from ndo_set_rx_mode to a work item. However, it still updates the private variables describing the filter state synchronously. Contrary to comments, the later use of these variables is not protected using the address lock, resulting in race conditions. Move the state update to a new function efx_farch_filter_sync_rx_mode() and make the Falcon-arch MAC configuration functions call that, so that its use is consistently serialised by the mac_lock. Invert and rename the promiscuous flag to the more accurate unicast_filter, and comment that both this and multicast_hash are not used on EF10.

EF10 functions don't have a fixed BAR size, and the minimum is not large enough for all the queues we might want to allocate. We have to find out the BAR size at run-time, and therefore phys_addr_channels and mem_map_size cannot be defined per-NIC-type. Change efx_nic_type::mem_map_size to a function pointer which is called to find the wanted memory map size (before probe). Replace efx_nic_type::phys_addr_channels with efx_nic::max_channels, to be initialised by the probe function. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

MCDI v2 adds a second header dword with wider command and length fields. It also defines extra error codes. Change the fallback error number for unknown MCDI error codes from EIO to EPROTO. EIO is treated as indicating the MCDI transport has failed and we need to reset the function, which is rather drastic. v2 error codes and lengths don't fit into completion events, so for a v2-capable transport, always read the response header rather then using the event fields.

Add efx_nic_type operations for the many efx_nic functions that need to be implemented different on EF10. For now, change most of the existing efx_nic_*() functions into inline wrappers. As a later step, we may be able to improve branch prediction for operations used on the fast path by copying the pointers into each queue/channel structure. Move the Falcon/Siena implementations to new file farch.c and rename the functions and static data to use a prefix of 'efx_farch_'. Move efx_may_push_tx_desc() to nic.h, as the EF10 TX code will also use it. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

Currently efx_stop_datapath() will try to flush our DMA queues (if DMA is enabled), then finalise software and hardware state for each queue. However, for EF10 we must ask the MC to finalise each queue, which implicitly starts flushing it, and then wait for the flush events. We therefore need to delegate more of this to the NIC type. Combine all the hardware operations into a new NIC-type operation efx_nic_type::fini_dmaq, and call this before tearing down the software state and buffers for all the DMA queues.

Enable RX DMA scattering iff an RX buffer large enough for the current MTU will not fit into a single page and the NIC supports DMA scattering for kernel-mode RX queues. On Falcon and Siena, the RX_USR_BUF_SIZE field is used as the DMA limit for both all RX queues with scatter enabled. Set it to 1824, matching what Onload uses now. Maintain a statistic for frames truncated due to lack of descriptors (rx_nodesc_trunc). This is distinct from rx_frm_trunc which may be incremented when scattering is disabled and implies an over-length frame. Whenever an MTU change causes scattering to be turned on or off, update filters that point to the PF queues, but leave others unchanged, as VF drivers assume scattering is off. Add n_frags parameters to various functions, and make them iterate: - efx_rx_packet() - efx_recycle_rx_buffers() - efx_rx_mk_skb() - efx_rx_deliver() Make efx_handle_rx_event() responsible for updating efx_rx_queue::removed_count. Change the RX pipeline state to a starting ring index and number of fragments, and make __efx_rx_packet() responsible for clearing it. Based on earlier versions by David Riddoch and Jon Cooper.
