This functionality adds two new instructions: #define BPF_MISCOP(code) ((code) & 0xf8) #define BPF_TAX 0x00 +#define BPF_COP 0x20 +#define BPF_COPX 0x40 #define BPF_TXA 0x80 It would be great if FreeBSD would reserve the opcodes. If you would like to backport the BPF coprocessor interface, the change is here: http://mail-index.netbsd.org/source-changes/2013/08/29/msg047090.html >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
