d215697fe1 sfc: make functions static
Make local functions and variable static. Do some rearrangement
of the string table stuff to put it where it gets used.

8fbca79130 sfc: Remove support for SFN4111T, SFT9001 and Falcon GMAC
SFN4111T never reached production and is not being used for internal
or customer testing.

Since we have no production Falcon boards using the SFT9001 or the
GMAC, remove support for them as well.

This driver has been mostly rewritten since Michael Brown's initial
work, so swap the order of the authors.

8880f4ec21 sfc: Add support for SFC9000 family (2)
This integrates support for the SFC9000 family of 10G Ethernet
controllers and LAN-on-motherboard chips, starting with the SFL9021
'Siena' and SFC9020 'Bethpage'.

Credit for this code is largely due to my colleagues at Solarflare:

d3245b28ef sfc: Refactor link configuration
Refactor PHY, MAC and NIC configuration operations so that the
existing link configuration can be re-pushed with:

	efx->phy_op->reconfigure(efx);
	efx->mac_op->reconfigure(efx);

and a new configuration with:

	efx->nic_op->reconfigure_port(efx);

(plus locking and error-checking).

We have not held the link settings in software (aside from flow
control), and have relied on asking the hardware what they are.  This
is a problem because in some cases the hardware may no longer be in a
state to tell us.  In particular, if an entire multi-port board is
reset through one port, the driver bindings to other ports have no
chance to save settings before recovering.

We only actually need to keep track of the autonegotiation settings,
so add an ethtool advertising mask to struct efx_nic, initialise it
in PHY init and update it as necessary.

Remove now-unneeded uses of efx_phy_op::{get,set}_settings() and
struct ethtool_cmd.

Much of this was done by Steve Hodgson <shodgson@solarflare.com>.

177dfcd80f sfc: Add support for sub-10G speeds
The SFC4000 has a separate MAC for use at sub-10G speeds.  Introduce
an efx_mac_operations structure with implementations for the two MACs.
Switch between the MACs as necessary.

PHY settings are independent of the MAC, so add get_settings() and
set_settings() to efx_phy_operations.  Also add macs field to indicate
which MACs the PHY is connected to.

8ceee660aa New driver "sfc" for Solarstorm SFC4000 controller.
The driver supports the 10Xpress PHY and XFP modules on our reference
designs SFE4001 and SFE4002 and the SMC models SMC10GPCIe-XFP and
SMC10GPCIe-10BT.
