Since PCI devices can be removed and there is a time between the physical removal to the RMV interrupt, the user may get invalid stats without any indication. This patch changes the stats_get API return value to be int instead of void. All the net PMDs stats_get dev ops are adjusted by this patch. Signed-off-by: Matan Azrad --- V2: Rebased patch with next_net master. Adjusted dpaa, octeontx and mrvl PMDs.
