I think this can make the cpu/kernel busy if there is any packets like ping destined to switch. I would assume it was set to 600pps to control such packets. How about setting it to 1000pps instead of increasing it 10x.

Code downloads are the pain point. With 1000pps we will see speeds ~ 1.4MB/s and it takes 7 minutes to download a full sonic image compared to 8.4MB/s with 6000pps. I think 6000pps is not that bad. Most of the switches are having an intel CPU and 8.4MB/s b/w for in-band access looks like a number on the conservative side.

@rajendra-dendukuri what about keep the current value as 600 and leave the user to change the setting?

@stcheng Are you suggesting that end user changes the setting in source code and re-compile's an image?
