Any deployment with very many small (/28 .. /32) subnets ?

2012-05-23 Thread Luigi Rizzo
Also related to my previous question on lookups, I believe some ISPs may have a huge number of very small subnets (say /28 or even smaller) attached to some kind of virtual interfaces (vlans, gif, tun,...). Can anyone comment on what the numbers are (i.e. 100-1k-10k subnets ?) and whether the subn

use of non-contiguous masks in address lookups ?

2012-05-23 Thread Luigi Rizzo
Hi, every now and then the issue comes up on whether we still need to support non-contiguous masks in address lookups. I seem to remember someone (perhaps on this list) making a case for their presence, but forgot the details. So, does anyone know of a practical use of non contiguous masks ? cheer

Intel 1G Tx hangs

in_ifaddr initialization

2012-05-23 Thread Mark Johnston
Hello, I've run into an issue related to the ordering of the steps in in.c:in_ifinit(). in_ifinit() gets called when an inet address gets added to an interface, and (loosely) it does the following: 1. Set the address of the in_ifaddr 2. Call the driver's ioctl handler (which generally seems to re

Folks, Can somebody please explain me why "tcp checsum" calculation is mandated in the freebsd network stack (tcp_input--->in6_cksum) albeit the card supports it? Probably Steve is the right person who can answer this. /Venkat On Wed, May 23, 2012 at 11:27 AM, Venkat Duvvuru wrote: > Ok. I fou
