- Get rid of exec(2)-ing tcpdump(7)
- Delete priority argument as it's impossible to capture traffic after a direct-action filter, so no reason to specify a priority other than 1
- Create tc filter with handle 0 rather than hardcode number, kernel will find the minimum available handle number.

Dynamical linking is so much trouble especially on kernel 4.19 and I wonder if I really need it. Using container is always a solution but still not portable as static elf. |
