Member Enumeration Documentation

MTUDiscoveryMode

template<OptLevel LEVEL>

enum class cosmos::IPOptBase::MTUDiscoveryMode : int

strong

Discovery mode settings used in setMTUDiscoveryMode().

The rather complex implications of these settings are best looked up in man 7 ip.

Enumerator
WANT	use per-route automatic settings
DONT	never do MTU path discovery
DO	always do MTU discovery
PROBE	set dont-fragment flag but ignore current MTU
