This patch adds support of configuring VF MAC from the host
for the HNS3 driver.
BTW, the parameter init in the hns3_init_mac_addr is
unnecessary now, since the MAC address will not read from
NCL_CONFIG when doing reset, so it should be removed,
otherwise it will affect VF's MAC address initialization.

This patch adds supports for setting VF trust by host. If specified
VF is trusted, then it can enable promisc(include allmulti mode).
If a trusted VF enabled promisc, and being untrusted, host will
disable promisc mode for this VF.
For VF will update its promisc mode from set_rx_mode now, so it's
unnecessary to set broadcst promisc mode when initialization or
reset.

This patch adds support for spoof check configuration for VFs.
When it is enabled, "spoof checking" is done for both mac address
and VLAN. For each VF, the HW ensures that the source MAC address
(or VLAN) of every outgoing packet exists in the MAC-list (or
VLAN-list) configured for RX filtering for that VF. If not,
the packet is dropped.

Throughout the driver there are several places where we wait
indefinitely for DPIO portal commands to be executed, while
the portal returns a busy response code.
Even though in theory we are guaranteed the portals become
available eventually, in practice the QBMan hardware module
may become unresponsive in various corner cases.

don't have a noticeable impact on performance but seem reasonable

First sk_msg_sg copy array is converted to a bitmap, zeroing that

Next two conditions are marked as unlikely, GCC seemed to had

Patch 4 adds parameters to tls_device_decrypted() to avoid

mlxsw: Query number of modules from firmware
Vadim says:
The patchset adds support for a new field "num_of_modules" of Management
General Peripheral Information Register (MGPIR), providing the maximum
number of QSFP modules, which can be supported by the system.
It allows to obtain the number of QSFP modules directly from this field,
as a static data, instead of old method of getting this info through
"network port to QSFP module" mapping. With the old method, in case of
port dynamic re-configuration some modules can logically "disappear" as
a result of port split operations, which can cause some modules to
appear missing.
Such scenario can happen on a system equipped with a BMC card, while PCI
chip driver at host CPU side can perform some ports "split" or "unsplit"
operations, while BMC side I2C chip driver reads the "port-to-module"
mapping.
Add common API for FW "minor" and "subminor" versions validation and
share it between PCI and I2C based drivers.
Add FW version validation for "minimal" driver, because use of new field
"num_of_modules" in MGPIR register is not backward compatible.
