What is the function of enhanced transmission selection in an FCoE environment?

A.
Provides available bandwidth to other classes of traffic when a particular class of traffic does
not use its allocated bandwidth

B.
Provides the capability to independently pause transmission of FCoE frames over each virtual
link

C.
Enables an FCoE switch to send a signal to other FCoE switches that need to stop or slow
down their transmissions

D.
Allows an FCoE switch to distribute configuration parameters to the converged network
adapters
