> 
> IP packet reassembly requires the MULTI_SEGS offload to be enabled in order
> to handle fragmented packets across multiple memory segments. However, the
> MBUF_FAST_FREE offload conflicts with MULTI_SEGS and cannot be enabled
> simultaneously.
> 
> Remove the MBUF_FAST_FREE offload to avoid conflicts with MULTI_SEGS.
