95c4c43 by Guy Harris (guy@xxxxxxxxxxxx):
Handle the new LINKTYPE_CAN_SOCKETCAN_HOSTENDIAN.
Unfortunately, only one libpcap code path puts the CAN ID in the
SocketCAN header in network byte order; the others leave it in host byte
order. Therefore, a new LINKTYPE_/DLT_ value was introduced, and
libpcap was changed to use that for the cases where the CAN ID is in
host byte order. Support them both.
This means we need to, when reading pcap and pcapng files, fix up the
CAN ID if the host that wrote the file has a different byte order from
ours (as libpcap also now does). This includes Linux "cooked" captures,
which can include CAN packets.
