...which reveals another build issue:

https://travis-ci.org/qemu/qemu/jobs/135006245

hw/net/e1000e.c: In function ‘e1000e_io_write’:
hw/net/e1000e.c:170:39: error: ‘idx’ may be used uninitialized in this
function [-Werror=uninitialized]
hw/net/e1000e.c: In function ‘e1000e_io_read’:
hw/net/e1000e.c:145:35: error: ‘idx’ may be used uninitialized in this
function [-Werror=uninitialized]

Combination of ust tracing backend plus gcc 4.6.3
having a tendency to used-uninitialized false positives?

The code itself looks fine so I think this is going to be
a case of adding an initialization somewhere to shut the
compiler up.
