This patch introduces a flow-based filter. So far, the very essential
packet fields are supported.
This patch is only the first step. There is a lot of potential performance
improvements possible to implement. Also a lot of features are missing
now. They will be addressed in follow-up patches.

This patch resolves false errors from MSGDMA in TX mSGDMA MM to ST
mode, and is a continuation of the patch recently submitted by Andrea
Oetken. The MSGDMA had a logic bug that masked detection of this issue
prior to Quartus 14.1/Build 164. When the MSGDMA logic bug was addr
It is hard to quickly find what you are looking for in the output of the
ip command. Color helps.
This patch adds a '-c' flag to highlight these with individual colors:
- interface name
- ip address
- mac address
- up/down state

There is no limit in netlink apart from UINT_MAX AFAICS. Allowing
UINT_MAX entries into a hash table
