Use "-H", not "-h", for the 802.11s option, and improve error reporting.
I was rudely surprised to find that "tcpdump -h" wasn't printing a usage message, and I'm the person who *added* the "-h" option. Make it "-H", and add an explicit "-h" option to print a usage message, so nobody else makes the same mistake. Also, don't clear opterr, so that if you give an illegal command-line option, you get an explanatory error message.
