[meta-freescale] UDP jumbo packet loss on T2080RDB and out-of-order receive

[Clemens Eisserer]

Hi,

I am trying to receive a stream of 9k jumbo frames on one of our
T2080RDBs (simply using recvfrom), however even a very low rate
(12MB/s on average) frequently UDP packages are lost. Furthermore the
packets are received out-of-order e.g. :0, 8, 1, 2, 10, 3, 11, 4, 5,
6, .....
While receiving the stream, I see an equal number of interrupts on
QMAN-Portal0 through QMAN-Portal-7.
PF_PACKET / PACKET_RX_RING for packet capturing also doesn't seem to
work - is this unsupported by DPAA?

So to summerize - any idea what could cause the following issues:
* UDP jumbo packet loss
* UDP jumbo packets are received out-of-order

Thank you in advance, Clemens
