> Subject: [PATCH v3 0/2] add mbuf fast free offload support
> 
> This patch adds support of the mbuf fast free offload to the
> transmit datapath. This offload allows to free the mbufs on
> transmit completion in the most efficient way. It requires
> the all mbufs were allocated from the same pool, have
> the reference counter value as 1, and have no any externally
> attached buffers.
> 
> The patchset is split in two parts, the first one is overall
> send loop optimization and can be ported back to stable release,
> and also is the preparation step before introducing the fast
> free offload. The second part provides the code for the feature.
