Subject: Re: [dpdk-stable] [PATCH] net/mlx5: fix Rx metadata leftovers
Date: Thu, 11 Mar 2021 19:58:10 +0000
Message-ID: <> (raw)
In-Reply-To: <>

From: Viacheslav Ovsiienko
> The Rx metadata might use the metadata register C0 to keep the values. The
> same register C0 might be used by kernel for source vport value handling,
> kernel uses upper half of the register, leaving the lower half for application
> usage.
> In the extended metadata mode 1 (dv_xmeta_en devarg is assigned with value
> 1) the metadata width is 16 bits only, the Rx datapath code fetched the entire
> 32-bit value of the metadata register and presented one to application. The
> patch provides data masking depending on the chosen metadata mode.
> Fixes: 6c55b622a956 ("net/mlx5: set dynamic flow metadata in Rx queues")
