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:
