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".
I use select on a BPF fd and find that I'm still seeing packets on the BPF device.
"See" as in "you can read from the device and they arrive", or "you can do a select() and you'll get a wakeup as soon as the store buffer gets transferred to the hold buffer, even if the timeout hasn't expired"?
