Switches supporting LLDP can communicate port attributes to connected devices.
Device drivers capable of accessing this information from the devices can use
the new callback get_switch_port_attrs() to report supported and enabled
settings in the card's adjacent switch port for display in ethtool.
Implementors have to use the respective SUPPORTED_SP_* and ENABLED_SP_* defines
to indicate the current settings.

[-- Attachment #1: ethtool_add_new_option-q.patch --]
[-- Type: text/plain, Size: 6042 bytes --]
Add new option '-q|--query-switch-port' to display information on the
adjacent switch port's settings as perceived by the respective NIC.
In the output,
- unsupported attributes are indicated as such ('unsupported'),
- supported but disabled attributes display 'no', and
- enabled attributes display 'yes'.
Attributes supported by this patch are
- forwarding modes:
standard (802.1) and reflective relay (RR) aka hairpin
- edge virtual bridging (EVB) related capabilities:
edge control protocol (ECP), VSI discovery and configuration protocol (VDP),
and retransmission timer exponent (RTE).
