> Subject: [PATCH bpf v3 5/9] i40e: fix registering XDP RxQ info
>
> Current way of handling XDP RxQ info in i40e has following problems:
> * when xsk_buff_pool is detached, memory model is not unregistered
> before
> registering a new one, this leads to a dangling xsk_buff_pool in the
> memory model table
> * frag_size is not updated when xsk_buff_pool is detached or when MTU
> is
> changed, this leads to growing tail always failing for multi-buffer
> packets.
>
> Couple XDP RxQ info registering with buffer allocations and
> unregistering with cleaning the ring.
