#3902 [FVT]makedhcp -n does not add virtual bridge xbr0 into dhcpd.conf
makedhcp -n does not add virtual bridge xbr0 into dhcpd.conf;
When there is no dhcpinterfaces,makedhcp -n create dhcpd.conf which will include network entries as well as certain general parameters such as a dynamic range and omapi configuration for linux.
work around :set dhcpinterfaces=xbr0 in site table;

Ifconfig uses the ioctl access method to get the full address information, which limits hardware addresses to 8 bytes.
Because Infiniband address has 20 bytes, only the first 8 bytes are displayed correctly.
Ifconfig is obsolete! For replacement check ip.
