* 2.4 kern: want to print TCP cwnd with every packet @ 2006-05-06 14:19 George P Nychis 2006-05-08 17:31 ` Stephen Hemminger 0 siblings, 1 reply; 2+ messages in thread From: George P Nychis @ 2006-05-06 14:19 UTC (permalink / raw) To: netdev Hi, I'd like to print the TCP cwnd for the sender, with every packet before it is sent out. This way i could plot the sender window over time to show TCP's behavior in certain conditions. I see in tcp_input.c several places where i could print the current window, but i'd have to add code in multiple places. I was wondering if there is any 1 place, right before a packet is sent out, that i could printk() tp->snd_cwnd Thanks! George ^ permalink raw reply [flat|nested] 2+ messages in thread
