> Subject: [PATCH v4 2/6] ethdev: move jumbo frame offload check to library
>
> Setting MTU bigger than RTE_ETHER_MTU requires the jumbo frame support,
> and application should enable the jumbo frame offload support for it.
>
> When jumbo frame offload is not enabled by application, but MTU bigger
> than RTE_ETHER_MTU is requested there are two options, either fail or
> enable jumbo frame offload implicitly.
>
> Enabling jumbo frame offload implicitly is selected by many drivers since
> setting a big MTU value already implies it, and this increases usability.
>
> This patch moves this logic from drivers to the library, both to reduce the
> duplicated code in the drivers and to make behaviour more visible.
