RH-Commit: [8/8] 3337c7737fa2eb33f1a27230ae1d6e0f2580a539 (thuth/qemu-kvm-cs9)
|
|
|
|
Now that we can boot from multiple boot devices, we have to make sure
|
|
to reinitialize static variables like rx_last_idx to avoid that they
|
|
contain garbage data during the second boot attempt (which can lead to
|
|
crashes when the code tries to access the wrong ring data).
