Detailed Description

Memif connection arguments.

Parameters
socket- Memif socket handle, if NULL default socket will be used. Default socket is only supported in global database (see memif_init). Custom database does not create a default socket (see memif_per_thread_init). Memif connection is stored in the same database as the socket.
secret- optional parameter used as interface authentication
num_s2m_rings- number of slave to master rings
num_m2s_rings- number of master to slave rings
buffer_size- size of buffer in shared memory
log2_ring_size- logarithm base 2 of ring size
is_master- 0 == master, 1 == slave
interface_id- id used to identify peer connection
interface_name- interface name
mode- 0 == ethernet, 1 == ip , 2 == punt/inject
