like… the range?? the versatility?? main character energy fr fr 👑

👑 TUNABLES 👑

the driver supports the following tunable parameters, which may be added to /boot/loader.conf or set via the sysctl(8) command:

  • hw.cbb.debug — non-zero values cause more verbose information to be printed to aid in debugging problems with the bridge chipset. so basically: not zero = the driver starts yapping and tells you what's actually going on with that bridge chipset. lowkey the move when something's acting up 🙈
