Subject: dnsmasq: Fix parameter 'limit'
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fsvn-archive%2Farchive.git;a=commitdiff_plain;h=342ba8cbff09bbc478a1cf711c0bc942314bd583;hp=fe33cff734a0508ce9830c1949501cad16f8e64f

dnsmasq: Fix parameter 'limit'

'limit' is actually the number of IP addresses to serve. See the use of ipcalc.sh.
For getting the expected number of IP addresses served, we have to decrement
limit by one.
