At 10Gbps, it is in FCoE:

http://en.wikipedia.org/wiki/Ethernet_flow_control

However, perhaps that isn't the link layer.  I've always wondered why
switched ethernet (which does the ISO layer-3 tasks of addressing,
routing over multiple point-to-point links and buffering) is called a
"link layer" by the internet community...

Cheers,
