Arnd Bergmann 7442c483b9 mlxsw: core: mlxsw: core: avoid -Wint-in-bool-context warning
A recently added function in mlxsw triggers a harmless compiler warning:

The warning is normally disabled, but it would be nice to enable
it to find real bugs, and there are no other known instances at
the moment.

Replace the negation with a zero-comparison, which also matches
the comment above it.

Vadim Pasternak 6bab45b4de mlxsw: core: Prevent duplication during QSFP module initialization
Verify during thermal initialization if QSFP module's entry is already
configured in order to prevent duplication.
Such scenario could happen in case two switch drivers (PCI and I2C
based) coexist and if after boot, splitting configuration is applied
for some ports and then I2C based driver is re-probed.
In such case after reboot same QSFP module, associated with split will
be discovered by I2C based driver few times, and it will cause a crash.

It could happen for example on system equipped with BMC (Baseboard
Management Controller), running I2C based driver, when the next steps
are performed:
- System boot
- Host side configures port spilt.
- BMC side is rebooted.

Gustavo A. R. Silva 78844068a7 mlxsw: spectrum: acl: Use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL)

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL)

Notice that, in this case, variable alloc_size is not necessary, hence
it is removed.

This code was detected with the help of Coccinelle.

Jiri Pirko 6b86168247 mlxsw: spectrum_acl: Enable vregion rehash per-profile
For MR ACL profile is does not make sense to do periodical rehashes, as
there is only one mask in use during the whole vregion lifetime.
Therefore periodical work is scheduled but the rehash never happens.
So allow to enable/disable rehash for the whole group, which is added
per-profile. Disable rehashing for MR profile.

Addition to the vregion list is done only in case the rehash is enable
on the particular vregion. Also, the addition is moved after delayed
work init to avoid schedule of uninitialized work
from vregion_rehash_intrvl_set(). Symmetrically, deletion from
the list is done before canceling the delayed work so it is
not scheduled by vregion_rehash_intrvl_set() again.

Jiri Pirko 2802aadfcf mlxsw: spectrum_acl: Split TCAM group structure into two
Make the existing group structure to contain fields needed for HW region
list manipulations. Move the rest of the fields into new vgroup struct.
This makes layering cleaner as the vgroup struct is on higher level than
low-level group struct. Also, this makes it possible to introduce
fine-grained locking.

Shalom Toledo d3eaf1085a mlxsw: spectrum: Add Spectrum-2 ASIC port type-speed operations
Add Spectrum-2 ASIC port type-speed operations.

Since multiple ethtool link modes are represented using a single bit in the
ASIC, the driver forces the user to configure all types per a specific
speed. For example, if the user wants to advertise 100Gbps 4-lanes speed,
he should advertise all the types of 100Gbps 4-lanes speed that are
supported by the ASIC as shown below:

  Supported ethtool bits for 100Gbps 4-lanes:
      0x1000000000      100000baseKR4 Full
      0x2000000000      100000baseSR4 Full
      0x4000000000      100000baseCR4 Full
      0x8000000000      100000baseLR4_ER4 Full

  Command for advertising 100Gbps 4-lanes:
      ethtool -s enp3s0np1 advertise 0xF000000000

fields extend the existing ones in order to handle more types and speeds.
For example, the new 200Gbps speed.
