Just wanted to post some summary notes on the recent OVS with DPDK Meetup we
had after the OVS conference. Thanks to everyone for the often lively
discussion.
I've collated and condensed Maryam's notes (Thank you Maryam) with my own.
Corrections and additions are welcome.
Usability
==========
* Command line options
- Create defaults which can be overridden on the command line.
-c 0x1
-n 4 (this will be in DPDK 2.2 also)
-socket-mem 1024,0
Another possibility might be saving these in Open_vSwitch other_config db
along with pmd-cpu-mask and the like. DPDK init could be delayed until the
config db is available I think.
It would seem to make sense to configure DPDK the same way as everything
else in OVS: through the database.
We already did something like that for ODP:

https://git.linaro.org/lng/odp-ovs.git/commitdiff/1b38b79f8017988ae41bae8b35d39798ad25e699
With the second patch we removed the need for external variables, which
ease up things even more.

Zoltan
