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.

An MDIO-based n-way restart does not make sense for any of the NICs
supported by this driver, nor for the coming EF100.
Unlike on Falcon (which was already split off into a separate driver),
the PHY on all of Siena, EF10 and EF100 is managed by MC firmware.
While Siena can talk to the PHY over MDIO, doing so for anything other
than debugging purposes (mdio_mii_ioctl) is likely to confuse the
firmware.
(According to the SFC firmware team, this support was originally added
to the Siena driver early in the development of that product, before
it was decided to have firmware manage the PHY.)

Since ethtool_common.o will be built into both sfc and sfc_ef100 drivers,
it can't use KBUILD_MODNAME directly. Instead, make it reference a
string provided by the individual driver code.

Since we only allocate VIs for the number of TXQs we actually need, we
cannot naively use "channel * TXQ_TYPES + txq" for the TXQ number, as
this has gaps (when efx->tx_queues_per_channel < EFX_TXQ_TYPES) and
thus overruns the driver's VI allocations, causing the firmware to
reject the MC_CMD_INIT_TXQ based on INSTANCE.
Thus, we distinguish INSTANCE (stored in tx_queue->queue) from LABEL
(tx_queue->label); the former is allocated starting from 0 in
efx_set_channels(), while the latter is simply the txq type (index in
channel->tx_queue array).
To simplify things, rather than changing tx_queues_per_channel after
setting up TXQs, make Siena always probe its HIGHPRI queues at start
of day, rather than deferring it until tc mqprio enables them.

Unprivileged functions (such as VFs) may set their MTU by use of the
'control' field of MC_CMD_SET_MAC_EXT, as used in efx_mcdi_set_mtu().
If calling efx_ef10_mac_reconfigure() from efx_change_mtu(), and the
NIC supports the above (SET_MAC_ENHANCED capability), use it rather
than efx_mcdi_set_mac().
