Not quite...  some of these take numeric arguments


options     IPFIREWALL
options     DUMMYNET
options     HZ=2000          # choose and appropriate value
options     DEVICE_POLLING   # in 4.8+ this may help net perf

# if you need to mess with these, read the kernel LINT file!

options    NMBCLUSTERS=1024
options    NMBUFS=4096
