samples/bpf: xdpsock: Add sched policy and priority support
By default, TX schedule policy is SCHED_OTHER (round-robin time-sharing).
To improve TX cyclic scheduling, we add SCHED_FIFO policy and its priority
by using -W FIFO or --policy=FIFO and -U <PRIO> or --schpri=<PRIO>.
A) From xdpsock --app-stats, for SCHED_OTHER policy:
$ xdpsock -i eth0 -t -N -z -T 1000 -b 16 -C 100000 -a
period min ave max cycle
Cyclic TX 1000000 53507 75334 712642 6250
B) For SCHED_FIFO policy and schpri=50:
$ xdpsock -i eth0 -t -N -z -T 1000 -b 16 -C 100000 -a -W FIFO -U 50
period min ave max cycle
Cyclic TX 1000000 3699 24859 54397 6250
