For new code that uses bpf_xhdr. If you don't change userland

Hm, MIPS. In this case you may need to check the struct emul to
differentiate o32 and n32. Or do they have the exact same structure

Hello,
I'm working on getting bpf(4) in a 64bit kernel play with a 32bit userland.
I've translated the ioctls, but I'm now stuck with read().
read(2) on a bpf device returns wire packets (no problems with this)
with a bpf-specific header in front of each packet. This bpf header is:
struct bpf_hdr {
10 matches
