b799f052a9 sfc: remove 'log-tc-errors' ethtool private flag
It no longer does anything now that we're using formatted extacks instead.
So we can remove the driver's whole get/set priv_flags implementation.

7c9d266d8f sfc: optional logging of TC offload errors
TC offload support will involve complex limitations on what matches and
 actions a rule can do, in some cases potentially depending on rules
 already offloaded.  So add an ethtool private flag "log-tc-errors" which
 controls reporting the reasons for un-offloadable TC rules at NETIF_INFO.

8cb03f4e08 sfc: Encapsulate access to netdev_priv()
Once we separate struct efx_nic memory from net_device memory the
existing usage will have to change.
Apart from the new function efx_netdev_priv() accesses have been
changed using:
  sed -i 's/netdev_priv/efx_netdev_priv/'

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.
