# Set up a new network device using the iproute2 package.
# Useful for running in non-OpenVZ kernels.
#
# Parameters are passed in environment variables.
# Required parameters:
# VEID - container ID
# HNAME - desired device name as seen by the host
# VNAME - desired device name as seen by the container
#
# If NNAME == VNAME, a network interface is moved to inside CT.
# Otherwise, a pair of veth devices (HNAME and VNAME) is created
# in container, and then the HNAME is moved to host namespace.
#
# Optional parameters (for HNAME != VNAME case):
# HMAC - host devices's MAC address
# VMAC - container device's MAC address
# BRIDGE - a bridge name to add HNAME to
# SKIP_CREATE - if set, device pair creation is skipped
