From: Matti Gottlieb <matti.gottlieb@xxxxxxxxx> Currently paging download buffer is freed during the the unloading of the opmode which happens when the driver is unloaded. This causes a memory leak since the paging download buffer is allocated every time we enable the interface, so the download buffer can be allocated many times, but only be freed once. Free paging download buffer during disabling of the interface.
