HP devices can send the three types of DCBX information to a server adapter supporting FCoE, but
cannot receive these types of DCBX information.

Enabling LLDP and DCBX TLV advertising
To enable the device to advertise APP, ETS, and PFC data through an interface, enable LLDP globally and
enable LLDP and DCBX TLV advertising on the interface.

Configuring APP parameters
The device negotiates with the server adapter by using the APP parameters to control the 802.1p priority
values of the protocol packets that the server adapter sends, and to identify traffic based on the 802.1p
priority values. For example, the device can use the APP parameters to negotiate with the server adapter
to set the 802.1p priority of all FCoE (protocol number 0x8906) and FIP (protocol number 0x8914)
