36 hours in the day? :)

It's not a lot, but we've submitted a couple of small patches. It's mostly
a matter of opportunity. We submit patches as we come across DPDK bugs or
find useful optos.

*Patches*

   - replaced O(n^2) sort in sort_by_physaddr() with qsort() from standard
   library <http://dpdk.org/dev/patchwork/patch/1955/>
   - Fixed spam from kni_allocate_mbufs() when no mbufs are free. If mbufs
   exhausted, 'out of memory' message logged at EXTREMELY high rates. Now logs
   no more than once per 10 mins <http://dpdk.org/dev/patchwork/patch/2062/>

*Reviews*

   - kni: optimizing the rte_kni_rx_burst
   <http://dpdk.org/dev/patchwork/patch/84/>
   - [PATCH RFC] librte_reorder: new reorder library
   <http://www.dpdk.io/ml/archives/dev/2014-October/006767.html>
   - [PATCH v2 09/17] i40e: clean log messages
   <http://dpdk.org/ml/archives/dev/2014-September/005133.html> (several in
   that series, but I figure 1 link is plenty)

*Other*
Not really patches or reviews, but trying to participate in the community:

   - VMware Fusion + DPDK and KNI
