Fedora 20 - network related question (bug?)

[Cristian Sava]

Hi all,
Having this working configuration

[root at s220 network-scripts]# ls ifcfg-*
ifcfg-Bridge_connection_1  ifcfg-lo  ifcfg-System_em1

[root at s220 network-scripts]# cat ifcfg-Bridge_connection_1
DEVICE=bridge0
STP=yes
BRIDGING_OPTS=priority=128
TYPE=Bridge
BOOTPROTO=none
IPADDR0=193.x.y.220

DEFROUTE=yes
IPV4_FAILURE_FATAL=yes

IPV6_AUTOCONF=yes

I added a nic card, and now ...

[root at s220 network-scripts]# ls ifcfg-*
ifcfg-Bridge_connection_1  ifcfg-lo  ifcfg-System_em1

[root at s220 network-scripts]# route

The question is: 
WHY ifcfg-p48p1 is missing from /etc/sysconfig/network-scripts ?

The Network GUI Tool shows p48p1 interface correctly and manages it.
What do I miss?
I don't find anything useful in the docs
