f50e8fcda6 sfc: receive packets from EF100 VFs into representors
If the source m-port of a packet in __ef100_rx_packet() is a VF,
 hand off the packet to the corresponding representor with
 efx_ef100_rep_rx_packet().

08d0b16ecb sfc: check ef100 RX packets are from the wire
If not, for now drop them and warn.  A subsequent patch will look up
 the source m-port to try and find a representor to deliver them to.

966b8266a4 sfc: fix boolreturn.cocci warning and rename function
check_fcs() was returning bool as 0/1, which was a sign that the sense
 of the function was unclear: false was good, which doesn't really match
 a name like 'check_$thing'.  So rename it to ef100_has_fcs_error(), and
 use proper booleans in the return statements.

068885434c sfc: check hash is valid before using it
On EF100, the RX hash field in the packet prefix may not be valid (e.g.
 if the header parse failed), and this is indicated by a one-bit flag
 elsewhere in the packet prefix.  Only call skb_set_hash() if the
 RSS_HASH_VALID bit is set.

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.

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.
