   Thank you for the hint. I tracked down t4fw_cfg via the Makefile
in the modules area.

   However, I'm not actually sure how it works at this point. When I
kldload if_cxgbe and check for t4fw_cfg it does not appear to be
loaded (kldstat -v | grep t4).

   Moving on, adding t4fw_cfg_load to loader.conf we end up with:

Id Refs Address            Size     Name
 1   17 0xffffffff80200000 15652a8  kernel
 2    1 0xffffffff81766000 4820     coretemp.ko
 3    1 0xffffffff8176b000 797b0    t4fw_cfg.ko
 4    1 0xffffffff817e5000 45b38    if_cxgbe.ko
 5    1 0xffffffff8182b000 11b78    ipmi.ko
 6    2 0xffffffff8183d000 2a30     smbus.ko

   and everything seems to work. I think this is worth a patch
to the man page at least:

   Thoughts?
