Re: [dpdk-dev] [PATCH 0/4] Broadcom 10G NIC Poll Mode Driver

[Jun Xiao <xiaojuntime@gmail.com>]

Hi Stephen,

Thanks for your great work on this!

Could you elaborate on a few things:
- What's the methodology used in the driver porting?
  e.g. what's the base source you ported from?
  what's the major change against the base source?
- What kind of tests have been done on Linux? any known limitations?

Thanks,
Jun
