Apparently, 4-6 XLAT scenarios can insert an empty fragment header into the
IPv6 header chain to indicate that fragmentation is supported in the host
IPv4 network. This header contains 0 for both the fragment_offset and MF
fields, so simply checking the value of frag_off passed to the
rmnet_frag_ipv6_skip_exthdr() function is not sufficient to properly catch
this rogue header. Instead, we need to implement a "less clever" version.

For wearables target, compilation happens along with PDK.
Due to compilation with PDK, tree structure changes to compile kernel
modules.
$BOARD_COMMON_DIR allows to use top-level-makefile specified value,
else it defaults to device/qcom/common for other targets.
