A technician is troubleshooting a server after a custom kernel build. The e1000e network driver was compiled as a separate module and copied into /lib/modules/$(uname -r)/. The driver depends on the ptp module, which is not yet present in the running kernel. Which single shell command will load the network driver and automatically insert any required dependency modules?
The modprobe utility consults the dependency information (modules.dep) generated by depmod and then loads the requested module together with any other modules it requires. Inserting the driver with insmod would not resolve ptp automatically, depmod -a only rebuilds the dependency database without loading anything, and lsmod merely displays the list of modules already present in the kernel.
