Hi David,
Since the kernel version is less than 3.6.0, support for VFIO is not there.
Could you please turn off VFIO in config/common_linuxapp and try with IGB_UIO?

Thanks,
-Sujith

Hello Sujith,

I just tried your patchset on my system but I can't get it to build :

$ make config T=x86_64-native-linuxapp-gcc && make
Configuration done
== Build scripts
== Build scripts/testhost
  HOSTCC testhost.o

[snip]

== Build lib/librte_pmd_enic
  CC enic_main.o
....../lib/librte_pmd_enic/enic_main.c:43:24: fatal error: linux/vfio.h: No such file or directory
compilation terminated.
make[3]: *** [enic_main.o] Error 1
make[2]: *** [librte_pmd_enic] Error 2
make[1]: *** [lib] Error 2
make: *** [all] Error 2

Looks like there is a problem with detecting vfio support and/or including the right header.

$ uname -a
Linux ... 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u3 x86_64 GNU/Linux
