  "message": "USB: serial: sierra driver memory reduction\n\nThis patch deals with reducing the memory footprint for sierra driver.\nThis optimization is aimed for embedded software customers.\n\nSome sierra modems can expose upwards of 7 USB interfaces, each possibly\noffering different services. In general, interfaces used for the\nexchange of wireless data require much higher throughput, hence require\nmore memory (i.e. more URBs) than lower performance interfaces. URBs\nused for the IN direction are pre-allocated by the driver and this patch\nintroduces a way to configure the number of IN URBs allocated on a\nper-interface basis. Interfaces with lower throughput requirements\nreceive fewer URBs, thereby reducing the RAM memory consumed by the\ndriver.\n\nNOTE1: This driver has always pre-allocated URBs for the IN direction.\n\nNOTE2: The number of URBs pre-allocated for the low-performance\ninterfaces has already been extensively tested in previous versions of\nthis driver.\n\nWe also added the capability to log function calls by adding DEBUG flag.\nPlease note that  this flag is commented out because this is the default\nstate\nfor it.\n\nSigned-off-by: Elina Pasheva \u003cepasheva@sierrawireless.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n",
