2020-08-03sfc_ef100: check firmware version at start-of-dayEdward Cree
Early in EF100 development there was a different format of event descriptor; if the NIC is somehow running the very old firmware which will use that format, fail the probe. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-07-27sfc_ef100: actually perform resetsEdward Cree
In ef100_reset(), make the MCDI call to do the reset. Also, do a reset at start-of-day during probe, to put the function in a clean state. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-07-27sfc_ef100: extend ef100_check_caps to cover datapath_caps3Edward Cree
MC_CMD_GET_CAPABILITIES now has a third word of flags; extend the efx_has_cap() machinery to cover it. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-07-27sfc_ef100: process events for MCDI completionsEdward Cree
Currently RX and TX-completion events are unhandled, as neither the RX nor the TX path has been implemented yet. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-07-27sfc_ef100: implement ndo_open/close and EVQ probingEdward Cree
Channels are probed, but actual event handling is still stubbed out. Stub implementation of check_caps is needed because ptp.c will call into it from efx_ptp_use_mac_tx_timestamps() to decide if it wants TXQs.

2020-07-27sfc_ef100: PHY probe stubEdward Cree
We can't actually do the MCDI to probe it fully until we have working MCDI, which comes later, but we need efx->phy_data to be allocated so that when we get MCDI events the link-state change handler doesn't NULL-dereference.

2020-07-27sfc_ef100: reset-handling stubEdward Cree
We don't actually do the efx_mcdi_reset() because we don't have MCDI yet. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-07-27sfc: skeleton EF100 PF driverEdward Cree
No TX or RX path, no MCDI, not even an ifup/down handler. Besides stubs, the bulk of the patch deals with reading the Xilinx extended PCIe capability, which tells us where to find our BAR. Though in the same module, EF100 has its own struct pci_driver, which is named sfc_ef100. A small number of additional nic_type methods are added; those in the TX (tx_enqueue) and RX (rx_packet) paths are called through indirect call wrappers to minimise the performance impact.
