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.

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.

In the loadbalance arp monitoring scheme, when a slave link change is
detected, the slave->link is immediately updated and slave_state_changed
is set. Later down the function, the rtnl_lock is acquired and the
changes are committed, updating the bond link state.
However, the acquisition of the rtnl_lock can fail. The next time the
monitor runs, since slave->link is already updated, it determines that
link is unchanged. This results in the bond link state permanently out
of sync with the slave link.
This patch modifies bond_loadbalance_arp_mon() to handle link changes
identical to bond_ab_arp_{inspect/commit}(). The new link state is
maintained in slave->new_link until we're ready to commit at which point
it's copied into slave->link.
NOTE: miimon_{inspect/commit}() has a more complex state machine
requiring the use of the bond_{propose,commit}_link_state() functions
which maintains the intermediate state in slave->link_new_state. The arp
monitors don't require that.
Testing: This bug is very easy to reproduce with the following steps.
1. In a loop, toggle a slave link of a bond slave interface.
2. In a separate loop, do ifconfig up/down of an unrelated interface to
create contention for rtnl_lock.
Within a few iterations, the bond link goes out of sync with the slave
link.

The current stmmac_adjust_link() part which handle speed have

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
