From: Robert Jordens <robertjo@phys.ethz.ch>

Some Apple Airport base stations (notably the "Snow" dual-ethernet ones)
send malformed association response packets that are one byte too long.
This causes parsing to fail. 
Allowing the packet to be one byte too long makes the parsing a bit more
lax but can hardly go wrong because _one_ spurious byte cannot be a
missed information element.
