[Drbd-dev] [PATCH 01/10] drbd: allow ping-timeout of up to 30 seconds

[Philipp Reisner]

From: Lars Ellenberg <lars.ellenberg at linbit.com>

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.
