From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.12; Mac_PowerPC)

Description of problem:
dhcpcd does reset the IFF_MULTICAST flag if it was set by the 
ethernet driver to signal it supports multcasting. This causes modern 
software that uses the MULTICAST flag to autoconfigure to skip the 
interface in question. An example is OpenSLP and some AppleTalk 

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

How reproducible:

Steps to Reproduce:
1. load your ethernet driver, I used a 3c59x
2. run ifconfig eth0, the MULTICAST flag is turned on
3. run dhcpcd eth0
4. after having aquired an IP address run ifconfig eth0 again

Actual Results:  the MULTICAST flag is gone.

Expected Results:  The MULTCAST flag should not have been 
touched at all by dhcpcd.

Bugzilla is being mean and won't let me mark this a duplicate of #48669

Anyways, this is fixed in rawhide, all should be well in the future.
