Shalom says:

Ethernet Management Datagrams (EMADs) are Ethernet packets sent between
the driver and device's firmware. They are used to pass various
configurations to the device, but also to get events (e.g., port up)
from it. After the Ethernet header, these packets are built in a TLV
format.

Up until now, whenever the driver issued an erroneous register access it
only got an error code indicating a bad parameter was used. This patch
set adds a new TLV (string TLV) that can be used by the firmware to
encode a 128 character string describing the error. The new TLV is
allocated by the driver and set to zeros. In case of error, the driver
will check the length of the string in the response and report it using
devlink hwerr tracepoint.

Series applied, thank you.
