Subject: [dpdk-dev] removing mbuf error flags
Date: Fri, 29 Apr 2016 14:25:07 +0200	[thread overview]
Message-ID: <572352A3.6030400@6wind.com> (raw)

Hi,

In rte_mbuf.h, some rx flags are set to 0 since a long time since
nearly 2 years. It means nobody use them. They were introduced by
the following commit:

  http://dpdk.org/browse/dpdk/commit/?id=c22265f6

As far as I understand, these flags were introduced to let the
application know that a received packet is invalid.

The 2 drivers using them are i40e and enic. But as this flags are 0
today, it means that invalid packets are silently given to the
application.

My opinion is that invalid packets should not be given to the
application and only a statistic counter should be incremented.
No application check these flags today (in examples, or testpmd).

I would like to remove these flags.
Thoughs?

Olivier
