# Only the Windows target has the 2 following licenses:
# - license/bsd-2-clause.txt
# - license/isc.txt
# which is related to a Windows getopt.[ch] compatibility layer.
# Since Buildroot is not used for Windows target, it is not listed
# here.
#
# All the userland files of DPDK have dual licences BSD or GPL/LGPL
# Since the Linux kernel modules had been removed from the DPDK, there
# is no GPL only code into the DPDK anymore.
# The usage of DPDK with Buildroot is for userland only, it means
# that for the dual licenced files, BSD clause is used but not the
# following ones:
# - license/gpl-2.0.txt
# - license/lgpl-2.1.txt
# See the DPDK's license/README for more details.
#
# The legacy and historical license of the DPDK is BSD-3-clause.
