Modified files:
sys/netgraph ng_bpf.c
Log:
Reduce stack usage by 256 bytes per call. It helps to avoid kernel
stack overflow in complicated traffic filtering setups.
There can be minor performance degradation for the MHLEN < len <= 256 case
due to additional buffer allocation, but it is a rare case.
