Seem there is a bug in the bash script, for 16c32g, it only changes rx-0, but we also need to change rx-1.

Because 16c32g has two network queues, one bind to CPU 0, the other to CPU 8, here we also need to avoid binding CPU 0 and 8 to RPS.

sudo sh -c 'echo fe > /sys/class/net/eth0/queues/rx-0/rps_cpus'

sudo sh -c 'echo fe00 > /sys/class/net/eth0/queues/rx-1/rps_cpus'

Hi great script! May I know whether is this the updated way to run TiDB on arm64? Or is there an updated way? Thanks!
