cpu_layout.sh - List physical CPUs, logical CPUs and no of cores per phy CPU.

eth_speed.sh - Print interface Tx/Rx rate every 1 second, stats from NIC port.

if_speed.sh - Print interface Tx/Rx rate every 1 second, stats from Kernel

irq_balance.sh - Spread NIC port queue interrupts across CPU cores

irq_display.sh - List CPU cores NIC port interrupts are assigned to

rxq_display.sh - List interface Rx queue to CPU mapping (RPS)

soft_irqs.sh - Print NET_TX and NET_RX soft IRQ rate

soft_net.sh - Print packet drop rates for RPS

tx_inflight.sh - Print no. of in-flight packets in each NIC Tx queue
