[dpdk-dev] [PATCH v3 0/2] add mbuf fast free offload support

[Matan Azrad]

 From: Viacheslav Ovsiienko
> 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.
