There are some unfortunate limitations in classifying incoming traffic.
It's been a while, but I think the rule is that Nexus 2000 devices can only
classify based on incoming 802.1p cos values.
It's a pretty strange and disappointing limitation for an edge device where
you're less likely to have incoming dot1q tags and you're less likely to
trust the other end of the link to mark its own traffic.
