How can I decode 0xf001 in wireshark!

please see attatchment

I span traffic on nexus 7010 control plane , I found many packet protocol field label 0xf001

 

we found nexus 7010 doesn't send spanning tree bpdu traffic  from control plane to outside  (root on this switch) for termapary moment , and cause access switch send bpdu to nexus 7010  , then 7010 mark this interface to dispute

  

But I found this bpdu traffic send from access switch hit nexus 7010   protocol marking 0xf001 . How can I decode this 0xf001 message, 

we want to find are there many bpdu send from access switch  hitting control plane  and cause nexus 7010 stp process is busy  and can't send bpdu temparary , I found same behavior when some wirus send many arp hit nexus 7010 .and 7010 doesn't send arp reply

 thank you

Tom
