* [PATCH 04/32] sfc: Always start Falcon using the XMAC
From: Ben Hutchings @ 2009-11-28 3:44 UTC (permalink / raw)
To: David Miller; +Cc: netdev, linux-net-drivers
From: Steve Hodgson <shodgson@solarflare.com>
The strap bits are only important on Falcon A and all production
boards using it have fixed-speed 10G PHYs.
Replace dummy MAC operations with default MAC operations.

From: Ben Hutchings @ 2009-11-28 3:45 UTC (permalink / raw)
To: David Miller; +Cc: netdev, linux-net-drivers
From: Matthew Slattery <mslattery@solarflare.com>
The "bug9141 workaround" of setting TX_FLUSH_MIN_LEN_EN should really
be considered as a normal bit of configuration rather than a
workaround.

* [PATCH 15/32] sfc: Turn pause frame generation on and off at the MAC, not the RX FIFO
From: Ben Hutchings @ 2009-11-28 3:49 UTC (permalink / raw)
To: David Miller; +Cc: netdev, linux-net-drivers
Pause frame generation is gated by both RX_XOFF_MAC_EN and an enable
bit in each MAC. RX_XOFF_MAC_EN bit always reads back as 0 so we need
to set it correctly every time we modify RX_CFG_REG. Simplify this by
always setting it to 1 and only changing the enable bits in the MACs.

* [PATCH 17/32] sfc: Refactor link configuration
From: Ben Hutchings @ 2009-11-28 3:49 UTC (permalink / raw)
To: David Miller; +Cc: netdev, linux-net-drivers
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>.

* [PATCH 25/32] sfc: Fold falcon_probe_nic_variant() into falcon_probe_nic()
From: Ben Hutchings @ 2009-11-28 3:51 UTC (permalink / raw)
To: David Miller; +Cc: netdev, linux-net-drivers
falcon_probe_nic_variant() does a lot less than it used to, and a
lot less than it claims to. Fold the remainder into its caller.

* [PATCH 27/32] sfc: Remove static PHY data and enumerations
From: Ben Hutchings @ 2009-11-28 3:51 UTC (permalink / raw)
To: David Miller; +Cc: netdev, linux-net-drivers
New NICs have firmware managing the PHY, and we will discover the PHY
capabilities at run-time. Replace the static data with probe() and
test_name() operations.

* [PATCH 28/32] sfc: Extend MTD driver for use with new NICs
From: Ben Hutchings @ 2009-11-28 3:51 UTC (permalink / raw)
To: David Miller; +Cc: netdev, linux-net-drivers
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.
