Hello all,
I am running FreeBSD 2.2.2 on a PPro 200 MHz PC. I have created a
loadable kernel module which will schedule IP-packets on user-defineable
interfaces and priorities. But it doesn't work correctly now :-(
What I want to do in the general ether_output() is basically this:
prioritize packets
check if there's more packets to read <-----------+
if yes |
read the next packet and insert into queue |
else |
start output |
|
How can I check if there are packets to read in some/all interfaces and
force the kernel to perform the read (and eventually write, which
calls ether_output)?
Thanks in advance,
Martti
