Hi all:
Here is a question about ofp-print command. I have found after running the
same ovs-ofctl ofp-print <pkt raw data> command for multiple times, the output
would be strange. like below(dl_vlan has been changed), Could anyone tell me
the reason ?
#ovs-ofctl ofp-print " 01 04 0098 00000000 00002320 0000001e 0000 0034 82 82 82
