Hi,
mod_cc(4) says:
Algorithm modules can be compiled into the kernel or loaded as
kernel modules using the kld(4) facility.
Maybe I'm dense, but I can't figure out how to statically compile mod_cc
modules into the kernel? (I'm using a PAE kernel w/o modules.)
Hints appreciated.

Hi,
i found a couple of problems in

rx_process_limit, the task is rescheduled so it can complete the work.
