Retained in nic.h are NIC-specific declarations such as the siena and ef10 nic_data structs and various farch functions. The EF100 driver will thus include nic_common.h but not nic.h.

When the VF driver loads, it can make an MCDI call to get the MAC address that the parent PF assigned it. The parent PF also assigns a mac address to its own vport because implicit creation of a vAdaptor will only work on evb ports with MAC addresses assigned. The vport MAC address needs to be stored in the PF's nic_data struct as it can later be changed on the vadaptor (and its net_dev struct). When removing a vport the original MAC address must be deleted. A new flag is needed in the VF data structure to identify whether a vport has been assigned to the VF. This is to determine whether it needs to be un-assigned before freeing the vport. Also, attempting to un-assign a vport which is not assigned will result in an EALREADY error.

sfc: create VEB vswitch and vport above default firmware setup 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: create vports for VFs and assign random MAC addresses The parent PF creates vports for all its child VFs and adds MAC addresses to these. When the VF driver loads, it can make an MCDI call to get the MAC address that the parent PF assigned it. The parent PF also assigns a mac address to its own vport because implicit creation of a vAdaptor will only work on evb ports with MAC addresses assigned. The vport MAC address needs to be stored in the PF's nic_data struct as it can later be changed on the vadaptor (and its net_dev struct). When removing a vport the original MAC address must be deleted. A new flag is needed in the VF data structure to identify whether a vport has been assigned to the VF. This is to determine whether it needs to be un-assigned before freeing the vport. Also, attempting to un-assign a vport which is not assigned will result in an EALREADY error.

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.

sfc: Add SR-IOV back-end support for SFC9000 family On the SFC9000 family, each port has 1024 Virtual Interfaces (VIs), each with an RX queue, a TX queue, an event queue and a mailbox register. These may be assigned to up to 127 SR-IOV virtual functions per port, with up to 64 VIs per VF. We allocate an extra channel (IRQ and event queue only) to receive requests from VF drivers. There is a per-port limit of 4 concurrent RX queue flushes, and queue flushes may be initiated by the MC in response to a Function Level Reset (FLR) of a VF. Therefore, when SR-IOV is in use, we submit all flush requests via the MC. The RSS indirection table is shared with VFs, so the number of RX queues used in the PF is limited to the number of VIs per VF.

sfc:On MCDI timeout, issue an FLR (and mark MCDI to fail-fast) 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: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S.

sfc: Move and rename Falcon/Siena common NIC operations 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: Ben Hutchings <bhutchings@solarflare.com>
