version 1.x.y
For latest Npcap 0.07 r17, it sho
Can you define the behaviour of 'not work' with BPF on tiger?
"Not work" as in "if you select on a BPF device and nothing else, you
will only wake up when the select timeout expires; the store buffer
getting transferred to the hold buffer won't trigger a wakeup".
