Subject: [dpdk-dev] [PATCH] app/testpmd: fix segment number check
Date: Fri, 11 Dec 2020 15:07:45 +0000
Message-ID: <1607699265-5238-1-git-send-email-viacheslavo@nvidia.com> (raw)
In-Reply-To: <dc2efa45-23e1-f974-dbab-775977d094d6@intel.com>

The --txpkts command line parameter was silently ignored due to
application was unable to check the Tx queue ring sizes for non
configured ports [1].

The "set txpkts <len0[,len1]*>" was also rejected if there
was some stopped or /unconfigured port.

This provides the following:

  - number of segment check is performed against
    configured Tx queues only

  - the capability to send single packet is supposed to
    be very basic and always supported, the setting segment
    number to 1 is always allowed, no check performed

  - at the moment of Tx queue setup the descriptor number is
    checked against configured segment number

Fixes: 8dae835d88b7 ("app/testpmd: remove restriction on Tx segments set")
