net: aquantia: PTP support for AQC devices
This patchset introduces PTP feature support in Aquantia AQC atlantic driver.
This implementation is a joined effort of aquantia developers:
Egor is the main designer and driver/firmware architect on PTP,
Sergey and Dmitry are included as co-developers.
Dmitry also helped me in the overall patchset preparations.
Feature was verified on AQC hardware with testptp tool, linuxptp,
gptp and with Motu hardware unit.
version3 updates:
- Review comments applied: error handling, various fixes
version2 updates:
- Fixing issues from Andrew's review: replacing self with
ptp var name, making ptp_clk_offset a field in the ptp instance.
devm_kzalloc advice is actually non applicable, because ptp object gets
created/destroyed on each network device close/open and it should not be
linked with dev lifecycle.
- Rearranging commit authorship, adding Egor as a ptp module main maintainer
- Fixing kbuild 32bit division issues

mlxsw: Update main pool computation and pool size limits
Petr says:
In Spectrum ASICs, the shared buffer is an area of memory where packets are
kept until they can be transmitted. There are two resources associated with
shared buffer size: cap_total_buffer_size and cap_guaranteed_shared_buffer.
So far, mlxsw has been using the former as a limit when validating shared
buffer pool size configuration. However, the total size also includes
headrooms and reserved space, which really cannot be used for shared buffer
pools. Patch #1 mends this and has mlxsw use the guaranteed size.
To configure default pool sizes, mlxsw has historically hard-coded one or
two smallish pools, and one "main" pool that took most of the shared buffer
(that would be pool 0 on ingress and pool 4 on egress). During the
development of Spectrum-2, it became clear that the shared buffer size
keeps shrinking as bugs are identified and worked around. In order to
prevent having to tweak the size of pools 0 and 4 to catch up with updates
to values reported by the FW, patch #2 changes the way these pools are set.
Instead of hard-coding a fixed value, the main pool now takes whatever is
left from the guaranteed size after the smaller pool(s) are taken into
account.
====================

allowed to be. However, the total size also includes headrooms and reserved
space, which really cannot be used for shared buffer pools.
Therefore convert mlxsw to use the latter resource as a limit. Adjust
hard-coded pool sizes to be the guaranteed size minus 256000 bytes for CPU
port pool. On Spectrum-1 that actually leads to an increase. A follow-up
patch will have this size calculated automatically.

net: phy: support 1000Base-X auto-negotiation for BCM54616S
This patch series aims at supporting auto negotiation when BCM54616S is
running in 1000Base-X mode: without the patch series, BCM54616S PHY driver
would report incorrect link speed in 1000Base-X mode.
Patch #1 (of 3) modifies assignment to OR when dealing with dev_flags in
phy_attach_direct function, so that dev_flags updated in BCM54616S PHY's
probe callback won't be lost.
Patch #2 (of 3) adds several genphy_c37_* functions to support clause 37
1000Base-X auto-negotiation, and these functions are called in BCM54616S
PHY driver.
Patch #3 (of 3) detects BCM54616S PHY's operation mode and calls according
genphy_c37_* functions to configure auto-negotiation and parse link
attributes (speed, duplex, and etc.) in 1000Base-X mode.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The BCM54616S PHY cannot work properly in RGMII->1000Base-X mode, mainly
because genphy functions are designed for copper links, and 1000Base-X
(clause 37) auto negotiation needs to be handled differently.
This patch enables 1000Base-X support for BCM54616S by customizing 3
driver callbacks, and it's verified to be working on Facebook CMM BMC
platform (RGMII->1000Base-KX):
- probe: probe callback detects PHY's operation mode based on
INTERF_SEL[1:0] pins and 1000X/100FX selection bit in SerDES 100-FX
Control register.
- config_aneg: calls genphy_c37_config_aneg when the PHY is running in
1000Base-X mode; otherwise, genphy_config_aneg will be called.
- read_status: calls genphy_c37_read_status when the PHY is running in
1000Base-X mode; otherwise, genphy_read_status will be called.
Note: BCM54616S PHY can also be configured in RGMII->100Base-FX mode, and
100Base-FX support is not available as of now.

====================
The dsa_switch structure represents the physical switch device itself,
and is allocated by the driver. The dsa_switch_tree and dsa_port structures
represent the logical switch fabric (eventually composed of multiple switch
devices) and its ports, and are allocated by the DSA core.
This branch lists the logical ports directly in the fabric which simplifies
the iteration over all ports when assigning the default CPU port or configuring
the D in DSA in drivers like mv88e6xxx.
This also removes the unique dst->cpu_dp pointer and is a first step towards
supporting multiple CPU ports and dropping the DSA_MAX_PORTS limitation.
Because the dsa_port structures are not tied to the dsa_switch structure
anymore, we do not need to provide an helper for the drivers to allocate a
switch structure. Like in many other subsystems, drivers can now embed their
dsa_switch structure as they wish into their private structure. This will
be particularly interesting for the Broadcom drivers which were currently
limited by the dynamically allocated array of DSA ports.
The series implements the list of dsa_port structures, makes use of it,
then drops dst->cpu_dp and the dsa_switch_alloc helper.

The attempt to improve performance by changing the PCIe max read request

to r8169 driver. In the vendor driver this has been removed long ago.
Obviously it had no effect, also in my tests I didn't see any
difference. Typically the max payload size is less than 512 bytes
anyway, and the PCI core takes care that the maximum supported value
is set. So let's remove fiddling with PCIe max read request size from
