"kernel driver" in "lspci" output I often use `lspci -v` to check the LKM in use for particular hardware device. LKMs are listed as "Kernel modules" and can be seen with `lsmod`. However, what is a "Kernel driver"? For example here: !bcma-pci-bridge on in lspci output Is the "bcma-pci-bridge" a module built into kernel(I'm using 3.11.0) and thus it's not loadable and thus it will not appear in `lsmod`, can not be unloaded with `modprobe -r` or checked with `modinfo`?

From checking `/boot/config-3.11.0-13-generic` (yours might be different), I would guess that it's built into the kernel, thus you can't unload/reload it.
