There's a rare pci_driver.probe failure of the VF driver that's caused by
PF/VF handshake going out of sync. The culprit is octeon_mbox_write() who
ignores an ack timeout condition; it just keeps unconditionally writing all
elements of mbox_cmd->data[] even when the other side is not ready for
them. Fix it by making each write of mbox_cmd->data[i] conditional to
having previously received an ack.
Also fix the octeon_mbox_state enum such that each state gets a unique
value. Also add ULL suffix to numeric literals in macro definitions.

Create a symbolic link in the network device's namespace named "phydev"

The mlxfw module is in charge of common logic needed to flash Mellanox
devices firmware, which consists of:
- Parse the Mellanox Firmware Archive version 2 (MFA2) format, which is
the format used to store the Mellanox firmware. The MFA2 format file can
hold firmware for many different silicon variants, differentiated by a
unique ID called PSID. In addition, the MFA2 file data section is
compressed using xz compression to save both file-system space and
memory at extraction time.
- Implement the firmware flash state machine logic, which is a common
logic for Mellanox products needed to flash the firmware to the device.
As the module is shared between different Mellanox products, it defines a
set of callbacks to be implemented by the specific driver for hardware
interaction.

The current stmmac_adjust_link() part which handle speed have
some if (has_platform) code and my dwmac-sun8i will add more of them.
So we need to handle better speed selection.
Moreover the struct link member speed and port are hard to guess their
purpose. And their unique usage are to be combined for writing speed.
So this patch replace speed/port by simpler
speed10/speed100/speed1000/speed_mask variables.
In dwmac4_core_init and dwmac1000_core_init, port/speed value was used
directly without using the struct link. This patch convert also their
usage to speedxxx.
