We're seeing a subset of our FCXs start sending invalid sflow packets 
after an upgrade to any of the v8 code (we've tried everything up to and 
including FCXR08010d).  At the same time, they stop sending us the same 
volume of sflow packets that they were prior to the upgrade.  
Post-upgrade, we only seem to get sflow packets from the 1gb ports, we 
get nothing from the 10gb ports.

Sflowtool reports: "flow_sample_element length error (expected 56, found 
52)" and the sflow guys have confirmed that the samples are not valid 
packets.

Has anyone else seen similar issues?  We aren't seeing this on all of 
our FCX's, and the problem goes away if we downgrade to 7.4. We've been 
scratching our heads trying to figure out why some work and some don't.
