add -I option for watch peak traffic, add --phy option for RDMA

[kirbyzhou]

add -I option, show traffic stats of each interval instead of one second. Which is useful for watch peak traffic.

add --phy option, show traffic stats of phy(nic) rx/tx bytes instead of rx/tx bytes. Which is useful for RDMA card.

Thank you for adding this! I was looking for a way to monitor RDMA traffic and this is working well. I'm using Mellanox NIC on Rocky 9.1 with inbox driver. I hope cockpit adds support for this too.

Can you share your ib/net device name？ I want to verify some problem.

Sure, it's called mlx5_0 according to ibv_devinfo. Is that what you meant? Or enp197s0f0np0 in ip.

Thanks. And can you try --list-props with your ib device to list all your property names?

Interesting to see this, because I have a similar implementation (for infiniband) that I did years ago in version 0.7.4. I recently applied the changes into git and pushed it here in a separated branch for references: https://github.com/Low-power/nload/tree/rivoreo-fork-infiniband
