This patch prepares ground for the next VF MAC address change fix.
It lets untrusted VF to delete any VF mac filter, but it still
doesn't let untrusted VF to add mac filter not setup by PF.
It removes information duplication in num_mac mac filters counter.
And improves exact h/w mac filters usage checking in the
i40e_check_vf_permission() function by counting mac2add_cnt.
It also improves logging because now all mac addresses will be validated

Since commit 92418fb1 ("i40e/i40evf: Use usec value instead of reg
value for ITR defines") the driver tracks the interrupt throttling
intervals in single usec units, although the actual ITRN/ITR0 registers are
programmed in 2 usec units. Most register programming flows in the driver
correctly handle the conversion, although it is currently not applied when
the registers are initialized to their default values. Most of the time
this doesn't present a problem since the default values are usually
immediately overwritten through the standard adaptive throttling mechanism,
or updated manually by the user, but if adaptive throttling is disabled and
the interval values are left alone then the incorrect value will persist.

Since the intended default interval of 50 usecs (vs. 100 usecs as
programmed) performs better for most traffic workloads, this can lead to
performance regressions.

This patch adds the correct conversion when writing the initial values to
the ITRN registers.

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

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.
====================

been using the former as a limit to determine how large a pool size is
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: NDavid 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.
