/* * Minimal BPF assembler * * Instead of libpcap high-level filter expressions, it can be quite * useful to define filters in low-level BPF assembler (that is kept * close to Steven McCanne and Van Jacobson's original BPF paper). * In particular for BPF JIT implementors, JIT security auditors, or * just for defining BPF expressions that contain extensions which are * not supported by compilers. * * How to get into it: * * 1) read Documentation/networking/filter.txt * 2) Run `bpf_asm [-c] ` to translate into binary * blob that is loadable with xt_bpf, cls_bpf et al.

USB: serial: pl2303: add ATEN device ID
Seems that ATEN serial-to-usb devices using pl2303 exist with different device ids. This patch adds a missing device ID so it is recognised by the driver. Signed-off-by: Marcel J.E. Mol <marcel@mesa.nl> Cc: stable <stable@vger.kernel.org> Signed-off-by: Johan Hovold <johan@kernel.org>
