Subject: [PATCH] prevent if_nametoindex being called with empty string
Calling if_nametoindex with an empty string will always return 0, but
on ARM linux platforms this call seems to be very expensive (~30ms),
adding a large overhead to calls such as QUdpSocket::writeDatagram()
Task-number: QTBUG-37092
Change-Id: Iad00867585d9534af1ddaee936dd4e4dc5e03611
