sfc: skeleton EF100 PF driver 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.

sfc_ef100: implement ndo_open/close and EVQ probing 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.
