d3cf7d8f20 net: dsa: mv88e6xxx: simplify SERDES code for Topaz and Peridot
By adding an additional serdes_get_lane implementation (for Topaz), we
can merge the implementations of other SERDES functions (powering and
IRQs). We can skip checking port numbers, since the serdes_get_lane()
methods inform if there is no lane on a port or if the lane cannot be
used for given cmode.

17deaf5cb3 net: dsa: mv88e6xxx: create serdes_get_lane chip operation
Create a serdes_get_lane() method in the mv88e6xxx operations structure.
Use it instead of calling the different implementations.
Also change the methods so that their return value is used only for
error. The lane number is put into a place referred to by a pointer
given as argument. If the port does not have a lane, return -ENODEV.
Lanes are phy addresses, so use u8 as their type.

609070133a net: dsa: mv88e6xxx: update code operating on hidden registers
This patch moves the functions operating on the hidden debug registers
into it's own file, port_hidden.c. The functions prefix is renamed from
mv88e6390_hidden_ to mv88e6xxx_port_hidden_, to be consistent with the
rest of this driver. The macros are prefixed with MV88E6XXX_ prefix, and
are changed not to use the BIT() macro nor bit shifts, since the rest of
the port.h file does not use it.

We also add the support for setting the Block Address field when
operating hidden registers. Marvell's mdio examples for SERDES settings
on Topaz use Block Address 0x7 when reading/writing hidden registers,
and although the specification says that block must be set to 0xf, those
settings are reachable only with Block Address 0x7.

4e6da7969f net: dsa: mv88e6xxx: support 2500base-x in SGMII IRQ handler
The mv88e6390_serdes_irq_link_sgmii IRQ handler reads the SERDES PHY
status register to determine speed, among other things. If cmode of the
port is set to 2500base-x, though, the PHY still reports 1000 Mbps (the
PHY register itself does not differentiate between 1000 Mbps and 2500
Mbps - it thinks it is running at 1000 Mbps, although clock is 2.5x
faster).
Look at the cmode and set SPEED_2500 if cmode is set to 2500base-x.
Also tell mv88e6xxx_port_setup_mac the PHY interface mode corresponding
to current cmode in terms of phy_interface_t.

e9bf96943b net: dsa: sja1105: Clear VLAN filtering offload netdev feature
The switch barely supports traffic I/O, and it does that by repurposing
VLANs when there is no bridge that is taking control of them.

Letting DSA declare this netdev feature as supported (see
dsa_slave_create) would mean that VLAN sub-interfaces created on sja1105
switch ports will be hardware offloaded. That means that
net/8021q/vlan_core.c would install the VLAN into the filter tables of
the switch, potentially interfering with the tag_8021q VLANs.

We need to prevent that from happening and not let the 8021q core
offload VLANs to the switch hardware tables. In vlan_filtering=0 modes
of operation, the switch ports can pass through VLAN-tagged frames with
no problem.

f53a7ad189 r8152: Set memory to all 0xFFs on failed reg reads
get_registers() blindly copies the memory written to by the
usb_control_msg() call even if the underlying urb failed.

This could lead to junk register values being read by the driver, since
some indirect callers of get_registers() ignore the return values. One
example is:
  ocp_read_dword() ignores the return value of generic_ocp_read(), which
  calls get_registers().

So, emulate PCI "Master Abort" behavior by setting the buffer to all
0xFFs when usb_control_msg() fails.

This patch is copied from the r8152 driver (v2.12.0) published by
Realtek (www.realtek.com).

100GbE Intel Wired LAN Driver Updates 2019-08-23

This series contains updates to ice driver only.

Dave adds logic for the necessary bits to be set in the VSI context for
the PF_VSI and the TX_descriptors for control packets egressing the
PF_VSI.  Updated the logic to detect both DCBx and LLDP states in the
firmware engine to account for situations where DCBx is enabled and LLDP
is disabled.  Fixed the driver to treat the DCBx state of "NOT_STARTED"
as a valid state and should not assume "is_fw_lldp" true automatically.
Since "enable-fw-lldp" flag was confusing and cumbersome, change the
flag to "fw-lldp-agent" with a value of on or off to help clarify
whether the LLDP agent is running or not.

Brett fixes an issue where synchronize_irq() was being called from the
host of VF's, which should not be done.

Michal fixed an issue when rebuilding the DCBx configuration while in
IEEE mode versus CEE mode, so add a check before copying the
configuration value to ensure we are only in CEE mode.

Jake fixes the PF to reject any VF request to setup head writeback since
the support has been deprecated.

Mitch adds an additional check to ensure the VF is active before sending
out an error message that a message was unable to be sent to a
particular VF.

Chinh updates the driver to use "topology" mode when checking the PHY
for status, since this mode provides us the current module type that is
available.  Fixes the driver from clearing the auto_fec_enable bit which
was blocking a user from forcing non-spec compliant FEC configurations.

Amruth does a refactor on the code to first check, then assign in the
virtual channel space.

Bruce updates the driver to actually update the stats when a user runs
the ethtool command 'ethtool -S <iface>' instead of providing a snapshot
of the stats that maybe from a second ago.

Akeem fixes up the adding/removing of VSI MAC filters for VFs, so that
VFs cannot add/remove a filter from another VSI.  We now track the
number of filters added right from when the VF resources get allocated
and won't get into MAC filter mis-match issue in the switch.

fbbdbc6473 bnxt_en: Fix allocation of zero statistics block size regression.
Recent commit added logic to determine the appropriate statistics block
size to allocate and the size is stored in bp->hw_ring_stats_size.  But
if the firmware spec is older than 1.6.0, it is 0 and not initialized.
This causes the allocation to fail with size 0 and bnxt_open() to
abort.  Fix it by always initializing bp->hw_ring_stats_size to the
legacy default size value.

bbb968e8b3 ice: Fix issues updating VSI MAC filters
VSI, especially VF could request to add or remove filter for another VSI,
driver should really guide such request and disallow it.
However, instead of returning error for such malicious request, driver
can simply return success.

In addition, we are not tracking number of MAC filters configured per
VF correctly - and this leads to issue updating VF MAC filters whenever
they were removed and re-configured via bringing VF interface down and
up. Also, since VF could send request to update multiple MAC filters at
once, driver should program those filters individually in the switch, in
order to determine which action resulted to error, and communicate
accordingly to the VF.

So, with this changes, we now track number of filters added right from
when VF resources allocation is done, and could properly add filters for
both trusted and non_trusted VFs, without MAC filters mis-match issue in
the switch...

Also refactor code, so that driver can use new function to add or remove
MAC filters.

In some circumstances, VF devices can be deactivated while a message is
in-flight. In that case, a series of scary error message will be
printed in the log. Since these are actually harmless, check for this
case and suppress them. No harm, no foul.

84a118ab58 ice: Rename ethtool private flag for lldp
The current flag name of "enable-fw-lldp" is a bit cumbersome.

Change priv-flag name to "fw-lldp-agent" with a value of on or
off.  This is more straight-forward in meaning.

f8af5bf5b4 ice: reject VF attempts to enable head writeback
The virtchnl interface provides a mechanism for a VF driver to request
head writeback support. This feature is deprecated as of AVF 1.0, but
older versions of a VF driver may still attempt to request the mode.

Since the ice hardware does not support head writeback, we should not
accept Tx queue configuration which attempts to enable it.

Currently, the driver simply assumes that the headwb_enabled bit will
never be set.

If a VF driver does request head writeback, the configuration will
return successfully, even though head writeback is not enabled. This
leaves the VF driver in a non functional state since it is assuming to
be operating in head writeback mode.

Fix the PF driver to reject any attempt to setup headwb_enabled.

42a179c80d ice: Copy dcbx configuration only if mode is correct
In rebuild DCB desired_dcbx_cfg was copy to local_dcbx_cfg, but
if DCBX mode is IEEE desired_dcbx_cfg is not initialized by DCBX
config from FW. Change logic to copy config value only if mode is
set to CEE.

If driver copy desired_dcbx_cfg to local_dcbx_cfg in IEEE mode there
is problem with globr. System is frozen after two or more globr.

64bcaec642 ice: Treat DCBx state NOT_STARTED as valid
When a port is not cabled, but DCBx is enabled in the
firmware, the status of DCBx will be NOT_STARTED.  This
is a valid state for FW enabled and should not be
treated as a is_fw_lldp true automatically.

Add the code to treat NOT_STARTED as another valid state.

1b0c3247a0 ice: Account for all states of FW DCBx and LLDP
Currently, only the DCBx status is taken into account to
determine if FW LLDP is possible.  But there are NVM version
coming out with DCBx enabled, and FW LLDP disabled.  This
is causing errors where the driver sees that DCBx is not
disabled, and then tries to register for LLDP MIB change
events, and fails.

Change the logic to detect both DCBx and LLDP states in the
FW engine.

0c3a6101ff ice: Allow egress control packets from PF_VSI
For control packets (i.e. LLDP packets) to be able to egress
from the main VSI, a bit has to be set in the TX_descriptor.
This should only be done for the main VSI and only if the
FW LLDP agent is disabled.  A bit to allow this also has to
be set in the VSI context.

Add the logic to add the necessary bits in the VSI context
for the PF_VSI and the TX_descriptors for control packets
egressing the PF_VSI.

IEEE 802.3ae clause 45 defines a modified MDIO protocol that uses a two
staged access model in order to increase the address space.

This patch adds support for C45 MDIO read and write accesses, which are
used whenever the MII_ADDR_C45 flag in the regnum argument is set.
In case it is not set, C22 accesses are used as before.
