Ben Hutchings says:
====================
1. Refactoring and cleanup in preparation for new hardware support.
2. Some bug fixes for firmware completion handling. (They're not known
to cause real problems, otherwise I'd be submitting these for net and
stable.)
3. Update to the firmware protocol (MCDI) definitions.

Conflicts:
drivers/net/wireless/iwlwifi/pcie/trans.c
include/linux/inetdevice.h
The inetdevice.h conflict involves moving the IPV4_DEVCONF values
into a UAPI header, overlapping additions of some new entries.
The iwlwifi conflict is a context overlap.

The macb driver only handle PHY description through platform_data
(macb_platform_data).
Thus, when using dt you cannot define phy properties like phy address or
phy irq pin.
This patch makes use of the of_mdiobus_register to add support for
phy device definition using dt.
A fallback to the autoscan procedure is added in case there is no phy
devices defined in dt.

drivers/platform/olpc/olpc-ec.c: initialise earlier
|
|
Being a low-level component, various drivers (e.g. olpc-battery) assume
that it is ok to communicate with the OLPC Embedded Controller during
probe. Therefore the OLPC EC driver must be initialised before other
drivers try to use it. This was the case until it was recently moved
out of arch/x86 and restructured around commits ac2504151f5a ("Platform:
OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86:
OLPC: switch over to using new EC driver on x86").
Use arch_initcall so that olpc-ec is readied earlier, matching the
previous behaviour.
Fixes a regression introduced in Linux-3.6 where various drivers such as
olpc-battery and olpc-xo1-sci failed to load due to an inability to
communicate with the EC. The user-visible effect was a lack of battery
monitoring, missing ebook/lid switch input devices, etc.

Currently we use struct efx_mtd to represent a physical NVRAM device
and struct efx_mtd_partition to represent a partition on that device.
But this only really makes sense for Falcon, as we don't know or care
whether MC-managed NVRAM partitions are on one or more physical
devices. It complicates iteration and provides little benefit.
Therefore:
- Replace the pointer to efx_mtd in mtd_info::priv with a pointer to efx_nic
- Move the falcon_spi_device pointer into the union in struct efx_mtd_partition
- Move the device name to efx_mtd_partition::dev_type_name
- Move the efx_mtd_ops pointer to efx_nic::mtd_ops
- Make efx_nic::mtd_list a list of partitions

On Falcon we implement MAC filtering requested by the stack using the
MAC wrapper's single unicast filter and multicast hash filter. Siena
is very similar, though MAC configuration is mediated by the MC.
Since MCDI operations may sleep, reconfiguration is deferred from
ndo_set_rx_mode to a work item. However, it still updates the private
variables describing the filter state synchronously. Contrary to
comments, the later use of these variables is not protected using the
address lock, resulting in race conditions.
Move the state update to a new function
efx_farch_filter_sync_rx_mode() and make the Falcon-arch MAC
configuration functions call that, so that its use is consistently
serialised by the mac_lock.
Invert and rename the promiscuous flag to the more accurate
unicast_filter, and comment that both this and multicast_hash are
not used on EF10.

MAC filters inserted on request from the stack (ndo_set_rx_mode)
should allow manual steering but not removal. Currently we have a
special case for Siena's all-multicast and all-unicast MAC filters,
but on EF10 we need to allow for steering of precise MAC filters as
well.
The EFX_FILTER_FLAG_RX_STACK flag changes the behaviour of replacement
and removal requests:
- Replacement *of* a filter with this flag never clears the flag but
does change steering and saved priority
- Replacement *by* a filter with this flag only sets the flag but does
not change steering
- Removal with priority < EFX_FILTER_PRI_REQUIRED really resets RX
steering and saved priority
This could support precise MAC filtering on Siena in future.
As a side-benefit, the default MAC filters are hidden from ethtool
until they are steered.

Aside from accelerated RFS, there is almost nothing that can be shared
between the filter table implementations for the Falcon architecture
and EF10.

farch.c. Introduce efx_nic_type operations for the implementation and
inline wrapper functions that call these.

Currently every call to efx_farch_filter_table_clear_entry() is
shortly followed by a conditional reset of the table limits. The new
limits (0) are not pushed to hardware until the next filter insertion.
Move both the reset and the hardware reconfiguration into
efx_farch_filter_table_clear_entry(), and add an explanatory comment.
Also, make consistent use of the term 'search limit' for the maximum
number of probes the NIC must make when searching for a filter of a
particular type.

The filter table(s) on EF10 are managed by firmware and will need
almost entirely separate code. Rename the types and functions used
within the existing implementation. The current definition of struct
efx_filter_spec is really implementation-specific, so we need to keep
it. For now, define a separate structure for the internal
representation but leave them identical.

While doing shutdown on the PCI device, the corresponding callback
function e1000e_shutdown() is trying to clear those correctable
errors on the upstream P2P bridge. Unfortunately, we don't have
the upstream P2P bridge under some cases (e.g. PCI-passthrou for
KVM on Power). That leads to kernel crash eventually.

This patch adds the ethtool callbacks necessary to change the RETA
indirection table from userspace.
In order to achieve this, we add the indirection table field (rss_indir_tbl)
in the board specific data structure (struct igb_adapter) to preserve the
values across hardware resets.
The indirection table must be initialized with default values in the
following cases:
* at module init time
* when the number of RX queues changes.
For this reason we add a new field (rss_indir_tbl_init) in igb_adapter
that keeps track of the number of RX queues. Whenever the number of RX
queues changes, the rss_indir_tbl is modified and initialized with default
values. The rss_indir_tbl_init is updated accordingly.
