Message-ID: <MW2PR12MB2492F9B4534E682170B6E1F9DF909@MW2PR12MB2492.namprd12.prod.outlook.com> (raw)

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.
