61 two flavors of JITs, the newer eBPF JIT currently supported on:

77 And the older cBPF JIT supported on the following archs:
79 - mips
80 - sparc
90 - 0 - disable the JIT (default value)
91 - 1 - enable the JIT

150 on dev_weight and is calculated multiplicative (dev_weight * dev_weight_rx_bias).

371 "2" is pointless after boot if these modules are built-in, so there is
