Hello, At the end, I implement in my application main loop the following procedure:
=> I get the current interface status using netlib_getifstatus() (devup) => check the link state using ioctl with the key SIOCGMIIREG and the register MII_MSR. => I check the result with the MII_MSR_LINKSTATUS flag (linkup) => Then I performed the following verifications: if (!devup && linkup) => netlib_ifup() if (devup && !linkup) => netlib_down() In fact, that's quite the same approach found in net_monitor. But, the net_monitor cannot be called due the lack of interruption.
