Hi All,

I am trying to understand the open flow rules written to the openvswitch.

I am using openvswitch with openflow version 1.3. In that I see flow 
rules like below

cookie=0x0, duration=133278.833s, table=0, n_packets=37283, 
n_bytes=15219696, tun_id=0x5a,in_port=1 
actions=load:0x2->NXM_NX_REG0[],goto_table:20
cookie=0x0, duration=133156.937s, table=0, n_packets=47834, 
n_bytes=4333742, tun_id=0x65,in_port=1 
actions=load:0x2->NXM_NX_REG0[],goto_table:20
cookie=0x0, duration=133285.759s, table=0, n_packets=1673, 
n_bytes=647400, tun_id=0x61,in_port=1 
actions=load:0x2->NXM_NX_REG0[],goto_table:20

What is the use of load:0x2->NXM_NX_REG0[] and where to use this action.

Thanks,
Madhu Chakravarthy.
