Modified files: (Branch: RELENG_4)
sys/netgraph ng_base.c
Log:
Increase the maximum message queue length to 256, and increase the
number of cached message structs to the same number. Modern NICs
(especially gigabit NICs) often have 64-256 or more receive packet
descriptors, so they can dump a lot of packets into the network
stack at once. With the old message queue limit, it was easy to
overflow the queue when using the ng_ether node.
I am committing this directly to RELENG_4. The queuing mechanism is
quite different in -current, and these limits don't apply there.
