SubjectRe: PF_PACKET: packets out of order

Hi!

NeTraMet v44b10 uses pcap(3) and complains about timestamps jumping
backwards. Looks like a PF_PACKET socket doesn't receive the packets
in the correct order. Some timestamps from a "tcpdump -tt":

RX: 1001465480.175100 [...]
TX: 1001465480.179111 [...]
RX: 1001465480.177315 [...]
^^^^^^
TX: 1001465480.180514 [...]
RX: 1001465480.179706 [...]

The receive packets are in order, as are the transmit packets.

Anything which absolutely _requires_ all TX and RX packets to
be in precise order, should really be fixed not to have such
a weird restriction.

Franks a lot,
