Bug 648524

Description of problem:
IPoIB child interface is a network interface over InfiniBand that works with the non default partition (i.e. not 0xffff). The name format of a child interface is ibX.abcd where X is the index of the HCA/port and abcd is the partition.
For the default partition the name of the interface is simply ibX (the .ffff is not present)
 
Now, the variable DEVICETYPE is calculated in 2 steps
1. if the TYPE variable is defined in ifcfg-ibX.abcd then DEVICETYPE is gets a value via a translation list
2. if step 1. yields not result then the value is calculated from the interface name by omitting the digits (e.g. ib0 --> ib)

Later on the variable DEVICETYPE is used to handle the specific interface according to it's special needs. For instance calling ifup-${DEVICETYPE}

For IPoIB child interface the calculation of DEVICETYPE gives wrong value (should be ib) since there is no translation for TYPE=InfiniBand (step 1.) and the formula of omitting the digits is wrong (it doesn't ommit the . )

The results can be various, for example:  not calling ifup-ib and ifdown-ib as required.

Version-Release number of selected component (if applicable):

8.45.30

How reproducible:
Create a configuration for ib0.8001 and see that it is not carried out

Steps to Reproduce:
1. Install openib-1.4.1-3.el5.noarch.rpm (to get ifup-ib)
2. edit a configuration for ib0.8001
3. load IPoIB by modprobe ib_ipoib
4. create ib0.8001 by echo 0x8001 > /sys/class/net/ib0/create_child
5. run ifup ib0.8001
  
Actual results:

script /etc/sysconfig/network-scripts/ifup-eth is called

Expected results:
script /etc/sysconfig/network-scripts/ifup-eth
