If you are hinting at debugging printf from in_cksum code that is present
on i386 and not on amd64, then don't worry, I've added similar printf to
amd64 in_cksum in my tree.

Hello,
this is a patch that switches entire IPv4 stack to network
byte order. That means, that at any layer any module should
expect IP header in network byte order. Any host byte order
values can be stored in local variables only and are never stored
into a packet itself.
The new code brin

Hello,
once the pfil(9) API was introduced in FreeBSD, our main packet filter,
the ipfw(4) worked in host byte order, that's why the pfil(9) API was
violated: the AF_INET hooks were entered with packet in host byte order.
If you look into pfil(9) manpage you'll see that it still declares

Yet another patch to test. Was suprising to me that lagg(4), which
aims at high-performance, still utilizes if_start.
Attached is patch that converts lagg(4) to use if_transmit. I'd

Well, the best idea for that case would be switch them to backup mode.

Hello networkers,

things a bit... and then make more hacking to restore the
