Subject: dhcpv4_assign: try 100 times to find a IP
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Fodhcpd.git;a=commitdiff_plain;h=0cbef0cd0dcc7f1c3c21a3f953228d18e01415da

dhcpv4_assign: try 100 times to find a IP

This is what the comment on the loop is saying.
Also change the srand comment to match to the actual code.
