ag71xx may have a PCS, but it does not appear to support configuration
of the PCS in the current code. The functions to get its state merely
report that the link is down, and the AN restart function is empty.
Since neither of these functions will be called unless phylink's legacy
flag is set, we can safely remove these functions and indicate this is
a modern driver.
Should PCS support be added later, it will need to be modelled using
the phylink_pcs support rather than operating as a legacy driver.

mtk_eth_soc has not been updated for commit 7cceb599d15d ("net: phylink:
avoid mac_config calls"), and makes use of state->speed and
state->duplex in contravention of the phylink documentation. This makes
reliant on the legacy behaviours, so mark it as a legacy driver.

ESL(Enhanced System Lockdown) was designed to lock PCI adapter firmware
images and prevent changes to critical non-volatile configuration data
so that uncontrolled, malicious or unintentional modification to the
adapters are avoided, ensuring it's operational state. Once this feature is
enabled, the device is locked, rejecting any modification to non-volatile
images. Once unlocked, the protection is off such that firmware and
non-volatile configurations may be altered.
Driver just reflects the capability and status of this through
the ethtool private flag.

The flow counters bulk query buffer is allocated once during
mlx5_fc_init_stats(). For PFs and VFs this buffer usually takes a little
more than 512KB of memory, which is aligned to the next power of 2, to
1MB. For SFs, this buffer is reduced and takes around 128 Bytes.
The buffer size determines the maximum number of flow counters that
can be queried at a time. Thus, having a bigger buffer can improve
performance for users that need to query many flow counters.
There are cases that don't use many flow counters and don't need a big
buffer (e.g. SFs, VFs). Since this size is critical with large scale,
in these cases the buffer size should be reduced.
In order to reduce memory consumption while maintaining query
performance, change the query buffer's allocation scheme to the
following:
- First allocate the buffer with small initial size.
- If the number of counters surpasses the initial size, resize the
buffer to the maximum size.
The buffer only grows and isn't shrank, because users with many flow
counters don't care about the buffer size and we don't want to add
resize overhead if the current number of counters drops.
This solution is preferable to the current one, which is less accurate
and only addresses SFs.

This patch causes the driver to perfer a valid MAC address from OF (if

address when neither of them is valid.
