Struct NxLearn 

pub struct NxLearn {
    pub idle_timeout: u16,
    pub hard_timeout: u16,
    pub priority: u16,
    pub cookie: u64,
    pub flags: u16,
    pub table_id: u8,
    pub fin_idle_timeout: u16,
    pub fin_hard_timeout: u16,
    pub specs: Vec<LearnSpec>,
}

NxLearn action (Nicira extension).

The learn action creates flows dynamically based on packet content. This is commonly used for MAC learning in OVS.

Fields

idle_timeout: u16

Idle timeout for learned flows (0 = no timeout)

hard_timeout: u16

Hard timeout for learned flows (0 = no timeout)

priority: u16

Priority of learned flows

cookie: u64

Cookie for learned flows

flags: u16

Learn flags

table_id: u8

Table to install learned flows

fin_idle_timeout: u16

Idle timeout when FIN received

fin_hard_timeout: u16

Hard timeout when FIN received

specs: Vec<LearnSpec>

Flow modification specs (match and action specifications)
