I'm still having a difficulty trying to understand what exactly
the intended proposal around this is. You may have just answered
my question but just to make sure: When people refer to
implementing or interpreting BPF in hardware, do they mean:
1) A limited BPF instruction set used as descriptive language
to define match/action logic?
2) A specific (versioned) BPF instruction set which hardware
can support?
3) The full BPF instruction set of the current kernel + all
defined helper functions and tail call support?
Would programs of 2) and 3) nature be simply rejected or would
the driver convert them somehow?
