Subject: dropbear: add option to set max auth tries
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6371159b4ae8b4dd94d6319ac805b0c26962bb14;p=openwrt%2Fstaging%2Fjogo.git

dropbear: add option to set max auth tries

Add a uci option to set the new max auth tries paramater in dropbear.
Set the default to 3, as 10 seems excessive.
