Default p4p1 changed to p2p1; works oddly

In my last thread I reported that my network stopped working.
Looking around, and comparing things with a CentOS 5 box,
I discovered that:

net4p1 was not there
net2p1 was there

I did not do anything intentional to eliminate p4p1. But
I was fiddling with libipq, so I cannot guarantee innocence.

So I did a "cp ifcfg-p4p1 ifcfg-p2p1", did a little editing,
and now p2p1 as a working network interface. Note that I
have only one network card.

It works, but not properly:
it won't start on boot;
it starts slowly and sometimes print odd stuff.

Below is activity immediately after boot to level 3,
and login as root. Note that the line containing the
number "98.919229" looks like something I might have typed,
but it is not. It just appeared. The "link up" and "link
down" lines appeared at roughly one second intervals.

It would be nice if I could get it to work correctly.

Thanks for your thoughts.

Mike,

I add that systemd logging is still broken. I think that
I need to get p4p1 back.

[root@mbrc40 myDaemon]# make enable
/bin/systemctl enable myDaemon.service
ln -s '/etc/systemd/system/myDaemon.service'
'/etc/systemd/system/multi-user.target.wants/myDaemon.service'
Failed to issue method call: Did not receive a reply. Possible causes
include: the remote application did not send a reply, the message bus
security policy blocked the reply, the reply timeout expired, or the network
connection was broken.
make: *** [enable] Error 1
