[dpdk-dev] [memnic PATCH v2] linux: fix build with kernel 3.3

[Olivier Matz <olivier.matz@6wind.com>]

Remove unused dev_ops functions.

The API of some functions (memnic_vlan_rx_add_vid,
memnic_vlan_rx_kill_vid) changed starting from 3.3 kernel. Instead of
using a #ifdef to handle the compilation on any kernel, we can just
remove these functions as they are not needed.

Hi Shimamoto-san,

Here is a new version of the patch, I think we don't need the following
functions so we can just remove them instead of keeping several dummy
functions for different kernel versions.

Let me know if you have any comment.

Regards,
Olivier
