ONVM library (#157)
Browse files Browse the repository at this point in the history 
These changes build the ONVM code as a library which can more easily be included with NFs.

Commit log:

* Create proper library for onvm_nflib, rename common.h to be less common.
* Include all shared files in the library, rename library libonvm.a.
* Make dequeing from NF rings simpler.
* Syntax cleanup
* Updating AES NF's Makefiles to use library
  • Loading branch information
