[dpdk-stable] patch 'examples/ip_fragmentation: fix Tx queues init' has been queued to LTS release 18.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/26/19. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/2c139f18efb74e54256c69667a53b7087de44042

Thanks.

Kevin Traynor

Subject: [PATCH] examples/ip_fragmentation: fix Tx queues init

[ upstream commit 9758b956dcf493e9cb73c965c791d2a50407ae6b ]

The application tries to configure queue ids larger
than the maximum allowed by MAX_TX_QUEUE_PER_PORT. This
causes the startup error:

"
  ...
  Initializing port 0 on lcore 0... Address:7C:FE:90:12:23:0D
  txq=0,0 txq=1,1 txq=2,2 txq=3,3 txq=4,4 txq=5,5 txq=6,6 txq=7,7 txq=8,8
  txq=9,9 txq=10,10 txq=11,11 txq=12,12 txq=13,13 txq=14,14 txq=15,15
  txq=16,16 Invalid TX queue_id=16

  EAL: Error - exiting with code: 1
    Cause: rte_eth_tx_queue_setup: err=-22, port=0
"

The error reproduces when lcores aren't set, and when the
machine has more than 16 cores.

Fixes: af75078fece3 ("first public release")
