Subject: [dpdk-dev] [PATCH] net/mlx5: fix metadata for compressed Rx CQEs
Date: Tue, 24 Mar 2020 12:15:18 +0000 [thread overview]
Message-ID: <1585052118-29013-1-git-send-email-viacheslavo@mellanox.com> (raw)
If packets with the same metadata are received with compressed CQE
the metadata value is not copied from the title packet in vectorized
rx_burst routines, it causes wrong metadat values seeing by
applications.
Fixes: a18ac6113331 ("net/mlx5: add metadata support to Rx datapath")
