getifaddrs doesnt deal with Infiniband device addresses

Hi All,

On attempting to run getifaddrs() on a system with IB
interfaces, the
interface names for the IB interfaces(ipv6) were corrupt.
The problem
lies with infiniband device addresses not being dealt with
correctly.
The sockaddr_ll structure has an address field (sll_addr)
which is of 8
bytes. However, infiniband devices have 20 byte hardware
addresses. As a
result, when the address is memcpy'ed into the sll_addr
field, the
interface name that follows this field is corrupted. Hence,
I have
extended the sll_addr char array to accommodate IB
addresses.
Could you  please share your thoughts on this?
