net/i40e does not drop packet with=
 too many segments

The test case is a bit artificial, but still makes sense. If application se=
nt
packet with too many segments which do not fit in Tx ring (or free space in=
 Tx
ring) the packet is reported as sent anyway.

The packet is not counted as sent in stats or output errors.

The following errors appear in logs:
i40e_dev_alarm_handler(): ICR0: malicious programming detected
i40e_handle_mdd_event(): Malicious Driver Detection event 0x02 on TX queue =
1 PF
number 0x00 VF number 0x00
 device 0000:01:00.0

Should be repeatable with testpmd which allows to sent packet with many
segments. E.g. setup Tx queue with 64 descriptors and try to send packet wi=
th
65 segments.

IMHO right behaviour in this case is to report the packet as transmitted in=
 Tx
burst return value, but drop and count it in oerrors. (Otherwise Tx could
stuck).
