Fragment extension headers are supported. First fragments have a fragment extension header (byte 21 = 0x2C) followed by a UDP header (byte 55 = 0x06). Middle and last fragments have a fragment extension header followed by data only (no TCP header). The first packet fragment has MF=1 with a zero offset. Middle fragments have MF=1 with a nonzero offset. The last packet fragment has MF=0 with a nonzero offset. Non-fragmented packets do not have a fragment extension header. A count is output for packet fragments but no errors are reported.
