Edward Cree d802b0ae65 sfc_ef100: extend ef100_check_caps to cover datapath_caps3 
MC_CMD_GET_CAPABILITIES now has a third word of flags; extend the
 efx_has_cap() machinery to cover it.

Edward Cree 965b549f3c 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.

Edward Cree 51b35a454e 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.
