[NET]: 2.6.13 breaks libpcap (and tcpdump)
Patrick McHardy says:
Never mind, I got it, we never fall through to the second switch
statement anymore. I think we could simply break when load_pointer
returns NULL. The switch statement will fall through to the default
case and return 0 for all cases but 0 > k >= SKF_AD_OFF.
Here's a patch to do just that.
I left BPF_MSH alone because it's really a hack to calculate the IP
header length, which makes no sense when applied to the special data.
