a21cf0a833 devlink: Add a new devlink port lanes attribute and pass to netlink
Add a new devlink port attribute that indicates the port's number of lanes.

Drivers are expected to set it via devlink_port_attrs_set(), before
registering the port.

The attribute is not passed to user space in case the number of lanes is
invalid (0).

622d3e9201 mlxsw: Set number of port lanes attribute in driver
Currently, port attributes like flavour, port number and whether the
port was split are set when initializing a port.

Set the number of lanes of the port as well so that it could be easily
passed to devlink in the next patch.

e3cbdaf146 net: systemport: fix double shift of a vlan_tci by VLAN_PRIO_SHIFT
Currently the u16 skb->vlan_tci is being right  shifted twice by
VLAN_PRIO_SHIFT, once in the macro skb_vlan_tag_get_pri and explicitly
by VLAN_PRIO_SHIFT afterwards. The combined shift amount is larger than
the u16 so the end result is always zero.  Remove the second explicit

f548a47626 bonding: don't need RTNL for ipsec helpers
The bond_ipsec_* helpers don't need RTNL, and can potentially get called
without it being held, so switch from rtnl_dereference() to
rcu_dereference() to access bond struct data.

Lightly tested with xfrm bonding, no problems found, should address the
syzkaller bug referenced below.

5cd24cbe7d bonding: deal with xfrm state in all modes and add more error-checking
It's possible that device removal happens when the bond is in non-AB mode,
and addition happens in AB mode, so bond_ipsec_del_sa() never gets called,
which leaves security associations in an odd state if bond_ipsec_add_sa()
then gets called after switching the bond into AB. Just call add and
delete universally for all modes to keep things consistent.

However, it's also possible that this code gets called when the system is
shutting down, and the xfrm subsystem has already been disconnected from
the bond device, so we need to do some error-checking and bail, lest we
hit a null ptr deref.

a20fafb92b net: dsa: rtl8366rb: Support the CPU DSA tag
This activates the support to use the CPU tag to properly
direct ingress traffic to the right port.

Bit 15 in register RTL8368RB_CPU_CTRL_REG can be set to
1 to disable the insertion of the CPU tag which is what
the code currently does. The bit 15 define calls this
setting RTL8368RB_CPU_INSTAG which is confusing since the
inverse meaning is implied: programmers may think that
setting this bit to 1 will *enable* inserting the tag
rather than disabling it, so rename this setting in
bit 15 to RTL8368RB_CPU_NO_TAG which is more to the
point.

After this e.g. ping works out-of-the-box with the
RTL8366RB.

a196e96bb6 bnxt_en: clean up VLAN feature bit handling
The hardware VLAN offload feature on our NIC does not have separate
knobs for handling customer and service tags on RX. Either offloading
of both must be enabled or both must be disabled. Introduce definitions
for the combined feature set in order to clean up the code and make
this constraint more clear. Technically these features can be separately
enabled on TX, however, since the default is to turn both on, the
combined TX feature set is also introduced for code consistency.

When changing channels, in a rare case that firmware cannot reserve the

revert to default when absolutely necessary.

v4: Revert RSS map to default during ring change only when absolutely
    necessary.

v3: Add warning messages when firmware cannot reserve the requested RX
    rings, and when the RSS table entries have to change to default.

v2: When changing channels, if the RSS table size changes and RSS map

791e5f61ae net: phy: mdio-octeon: Cleanup module loading dependencies
To ensure that the octeon MDIO driver has been loaded, the Cavium
ethernet drivers reference a dummy symbol in the MDIO driver. This
forces it to be loaded first. And this symbol has not been cleanly
implemented, resulting in warnings when build W=1 C=1.

Since device tree is being used, and a phandle points to the PHY on
the MDIO bus, we can make use of deferred probing. If the PHY fails to
connect, it should be because the MDIO bus driver has not loaded
yet. Return -EPROBE_DEFER so it will be tried again later.

Additionally, add a MODULE_SOFTDEP() to give user space a hint as to
what order it should load the modules.

c7b04d1030 net: phy: cavium: Improve __iomem mess
The MIPS low level register access functions seem to be missing
__iomem annotation. This causes lots of sparse warnings, when code
casts off the __iomem. Make the Cavium MDIO drivers cleaner by pushing
the casts lower down into the helpers, allow the drivers to work as
normal, with __iomem.

bus->register_base is now an void *, rather than a u64. So forming the
mii_bus->id string cannot use %llx any more. Use %px, so this kernel
address is still exposed to user space, as it was before.

3f2edd309f net: phy: at803x: Avoid comparison is always false warning
By placing the GENMASK value into an unsigned int and then passing it
to PREF_FIELD, the type is reduces down from ULL. Given the reduced
size of the type, the range checks in PREP_FAIL() are always true, and
-Wtype-limits then gives a warning.

By skipping the intermediate variable, the warning can be avoided.

104:          0   sx1503q  13 Edge      sff2-tx-fault

The sffX indicates the SFP the los and tx-fault are associated with.

5ab903418a net: qed: sanitize BE/LE data processing
Current code assumes that both host and device operates in Little Endian
in lots of places. While this is true for x86 platform, this doesn't mean
we should not care about this.

This commit addresses all parts of the code that were pointed out by sparse
checker. All operations with restricted (__be*/__le*) types are now
protected with explicit from/to CPU conversions, even if they're noops on
common setups.

I'm sure there are more such places, but this implies a deeper code
investigation, and is a subject for future works.

365cd2cee0 net: qed: correct qed_hw_err_notify() prototype
Change the prototype of qed_hw_err_notify() with the following:
* constify "fmt" argument according to printk() declarations;
* anontate it with __cold attribute to move the function out of
  the line;
* annotate it with __printf() attribute;

This eliminates W=1+ warning:

drivers/net/ethernet/qlogic/qed/qed_hw.c: In function
‘qed_hw_err_notify’:
drivers/net/ethernet/qlogic/qed/qed_hw.c:851:3: warning: function
‘qed_hw_err_notify’ might be a candidate for ‘gnu_printf’ format
attribute [-Wsuggest-attribute=format]
 len = vsnprintf(buf, QED_HW_ERR_MAX_STR_SIZE, fmt, vl);
 ^~~

as well as saves some code size:
