/* * 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.

usbnet: pegasus: Use net_device_stats from struct net_devicends-private-remove
Instead of using a private copy of struct net_device_stats in struct pegasus, use stats from struct net_device. Also remove the now unnecessary .ndo_get_stats function. Cc: Petko Manolov <petkan@nucleusys.com> Cc: linux-usb@vger.kernel.org Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
