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)
