FCS-Err, Rcv-Err increasing in tandem

Current situation:
Nexus 93180YC-EX is a core switch with connections to the rest of the network.
Nexus 5548 has a connection to the Nexus 93180YC-EX.
Nexus 5548 has only the Wireless Controller connected to it.
Traffic across the Nexus 5548 consists of:
a) Wireless AP tunnels terminating on the Wireless Controller
b) Wireless client traffic

Have replaced SFP+, certified fiber jumpers, SFP-H10GB-C jumpers to both problem interfaces, no change. Suspect it is a particular type of traffic as opposed to physical layer problems.
