Allow to input multiple (IPs in command/commands) from stdin

[interduo]

Problem:
Reloading of XDP many rules (8k+) takes too much time. At the end it cases Little packet loss.

I suggest to make:
[xdp_iphash_to_cpu_cmdline.c] to allow for multiple IPs in one command or aggregate multiple commands from file or - - batch command (like tc command).

Other way for resolving that could be to load the rules to another set and then change active set.

...or maybe there is another metod or resolving that problem?

That should be doable, in principle. However, you mentioned you were using libreqos; I'm not sure that libreqos uses xdp-cpumap-tc as-is, so you may be better off opening an issues with them?

Awesome!

Problems should be repaired in source. Pure xdp-cpumap-tc from gitrepo is also affected - just try to load firstly 1rule and then 4-5K enteries using XDP. See the difference.

Right; well, I'm certainly not opposed to merging a pull request that implements batching. However, I am also not planning to work on implementing this myself :)
