[dpdk-dev] [PATCH v6 00/15] remove mbuf userdata

[Thomas Monjalon]

30/10/2020 18:44, Thomas Monjalon:
> The mbuf field userdata (aliased as udata64)
> was announced to be removed for two reasons:
>   - applications, libraries and drivers used the same field
>     for different purposes, with a risk of usage conflict.
>   - this field always used 8 bytes even if unneeded
> 
> Some dynamic fields are created when needed to replace
> the big static userdata field.
> As a consequence, 8 bytes can be re-allocated to dynamic fields.
> 
> This mbuf layout change is important to allow adding more features
> (consuming more dynamic fields) during the next year.
