Since these packets (coded, fragmented) cannot be decoded/reassembled easily these packets are only identified and some basic header informations are shown. Also not all TVLVs in the header were shown. The mcast part was dropped and thus the debugging of the new mcast feature flags was not possible with batctl. Kind regards, Sven Sven Eckelmann (3): batctl: tcpdump: Add support for MCAST TVLV batctl: tcpdump: Add support for unicast fragmentation batctl: tcpdump: Add support for coded packets tcpdump.c | 110 +++++++++++++++++++++++++++++++++++++++++++++++++++++- tcpdump.h | 1 + 2 files changed, 110 insertions(+), 1 deletion(-) -- 2.20.1
