Re: Plan to move all network components to NetworkPkg

["Gao, Liming" <liming.gao@intel.com>]

Siyuan:
  Could you list the mapping between current location and new location of Network IPv4 stack? It will be easy to be understood. 

  And, I prefer to change the platform DSC/FDF per each BZ. That means I expect two commits in DSC/FDF. One is for BZ 1278, another is for 1293. The different commit is for the different change. 

Thanks
Liming
