2022-07-22sfc: support passing a representor to the EF100 TX pathEdward Cree
A non-null efv in __ef100_enqueue_skb() indicates that the packet is from that representor, should be transmitted with a suitable option descriptor (to instruct the switch to deliver it to the representee), and should not be accounted to the parent PF's stats or BQL.

2020-09-05sfc: make ef100 xmit_more handling look more like ef10'sEdward Cree
This should cause no functional change; merely make there only be one design of xmit_more handling to understand. As with the EF10/Siena version, we set tx_queue->xmit_pending when we queue up a TX, and clear it when we ring the doorbell (in ef100_notify_tx_desc). While we're at it, make ef100_notify_tx_desc static since nothing outside of ef100_tx.c uses it. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2020-08-03sfc_ef100: TX path for EF100 NICsEdward Cree
Includes checksum offload and TSO, so declare those in our netdev features. 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: 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.
