Subject: drbd: allow ping-timeout of up to 30 seconds
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=071cf1c9a7043660be08358e4b508f62120f224b;p=openwrt%2Fstaging%2Fblogic.git

drbd: allow ping-timeout of up to 30 seconds

Allow up to 300 centi-seconds to be configured for the "ping timeout".
There may be setups where heavy congestion, huge buffers, and asymmetric
bandwidth limitations may need a "huge" ping-timeout as work-around
for "spurious connection loss" problems.
