This makes efx_pci_remove_main() more obviously the inverse of
efx_pci_probe_main(), and matches our out-of-tree driver.

Subject: sfc: Move MTD probe after netdev registration and name allocation

The MTD partition is named based on the netdev name, which is set to
'eth%d' before registration.  Also, the MTD partition will currently
be left registered if netdev registration fails.

Fix both these problems by moving the MTD probe after netdev
registration.  Hold the RTNL to serialise this with the netdev
notifier that calls efx_mtd_rename().

Subject: sfc: Use a single blink implementation

Only some PHYs have firmware support for a LED blink mode, so we
currently blink the others in a timer function.  Since all PHYs have
simple on and off modes, we don't gain anything by using multiple
blink implementations.  Also, since we have a process context there
is no need to use a timer.

From 981fc1b4b8cc6bfe8c6f0c07052e25738d959c68 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Mon, 23 Nov 2009 16:04:23 +0000
Subject: sfc: Rename efx_board::init_leds to init_phy and use for SFN4111T

efx_board::init_leds was introduced as a second stage of
initialisation because of the inter-dependency between the board and
PHY.  We want to move board initialisation into NIC probing, which is
too early to use MDIO, so SFN4111T initialisation also needs to be
split.

From 278c0621fbc4ef52177969edb6f07352da816fdb Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Mon, 23 Nov 2009 16:05:12 +0000
Subject: sfc: Make board information explicitly Falcon-specific

Rename struct efx_board to struct falcon_board.

Introduce and use inline function to look up board info from struct
efx_nic, in preparation for moving it.

Move board init and fini calls into NIC probe and remove functions.

From f5e7adc3d4aa8edab63bb63f0ce5fe92c3dd7604 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Mon, 23 Nov 2009 16:07:30 +0000
Subject: sfc: Combine high-level header files

All files that include ethtool.h, rx.h or tx.h are also including
efx.h, and there is no good reason to separate out the few
declarations they contain.  Therefore fold them into efx.h.

Define name tables for these enumerations in a similar way as for
loopback.  Move the loopback name table together with them.

Subject: sfc: Hold MAC lock for longer in efx_init_port()

Although efx_init_port() is only called at probe time and so cannot
race with port reconfiguration, most of the functions it calls can
expect to be called with the MAC lock held.

Subject: sfc: Split MAC stats DMA initiation and completion
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From: Steve Hodgson <shodgson@solarflare.com>

Currently we initiate MAC stats DMA and busy-wait for completion when
stats are requested.  We can improve on this with a periodic timer to
initiate and poll for stats, and opportunistically poll when stats are
requested.

Since efx_nic::stats_disable_count and efx_stats_{disable,enable}()
are Falcon-specific, rename them and move them accordingly.

Subject: sfc: Simplify XMAC link polling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From: Steve Hodgson <shodgson@solarflare.com>

Only the XMAC on Falcon needs help from the driver to poll and reset
the MAC-PHY link (XAUI); GMII is a simple parallel bus and on later
NICs firmware takes care of the XAUI link.  Also, an XMAC interrupt
currently schedules a work item which simply clears a flag
(efx_nic::mac_up) to be checked by the regular monitor (or the next
link reconfiguration, if that is sooner).

Rename the flag to xmac_poll_required, changing its sense.  Remove the
needless indirection and just set the flag immediately.  Call
falcon_xmac_poll() directly where required.

Add a new generic operation mac_op::check_fault to check the link
outside of regular monitoring, as required during self-tests.

(Note that this leaves us with an unused work item, but we will
immediately have another use for it.)

Subject: sfc: Change MAC promiscuity and multicast hash at the same time
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From: Steve Hodgson <shodgson@solarflare.com>

Currently we can set multicast hash immediately (in atomic context)
but must delay setting MAC promiscuity.  There is not that much
point in deferring one but not the other, and setting the multicast
hash on Siena will involve a firmware request.  So process them
both in efx_mac_work().

Also, set the broadcast bit in the multicast hash in
efx_set_multicast_list(), since this is required for both Falcon and
Siena.

From fdaa9aed21c8c8b529f3c94a5ffa138bf3360b75 Mon Sep 17 00:00:00 2001
From: Steve Hodgson <shodgson@solarflare.com>
Date: Sat, 28 Nov 2009 05:34:05 +0000
Subject: sfc: Simplify PHY polling

Falcon can generate events for LASI interrupts from the PHY, but in
practice we have never implemented this in reference designs.  Instead
we have polled, inserted the appropriate events, and then handled the
events later.  This is a waste of time and code.

Instead, make PHY poll functions update the link state synchronously
and report whether it changed.  We can still make use of the LASI
registers as a shortcut on the SFT9001.

boards using it have fixed-speed 10G PHYs.

Replace dummy MAC operations with default MAC operations.

From d3245b28ef2a45ec4e115062a38100bd06229289 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Sun, 29 Nov 2009 03:42:41 +0000
Subject: 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>.

Subject: sfc: Extend MTD driver for use with new NICs

In new NICs flash is managed by firmware and we will use high-level
operations on partitions rather than direct SPI commands.  Add support
for multiple MTD partitions per flash device and remove the direct
link between MTD and SPI devices.  Maintain a list of MTD partitions
in struct efx_nic.

From 8880f4ec21e668dcab3c6d387524a887e5bcbf73 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Sun, 29 Nov 2009 15:15:41 +0000
Subject: 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:

   Guido Barzini
   Steve Hodgson
   Kieran Mansley
   Matthew Slattery
   Neil Turton
