Subject: dnsmasq: Make the --dhcp-host logic easier to understand
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f65ff468f760b982ab2257c7eb4cee3cff05a28e;p=openwrt%2Fstaging%2Fdangole.git

dnsmasq: Make the --dhcp-host logic easier to understand

Use an if/else statement to cover the two different syntaxes.  Add
comments explaining what the end results should look like.

This patch should not change the script's output.
