Hi, I am using FreeBSD alpha2 amd64 on my router and after packet loaded test attack I am taking "ping: sendto: No buffer space available" error when running ping from router to victim directoion. The nic is "Intel 82599EB". Whenever this problem began to show, I can track the packages by tcpdump but I think the packages can not be created physically when they are reached physical layer. Doing the nic down/up can not be solved the problem.
When I testing I have found the "dev.ix.0.link_irq" value is increased very differently from other nic's link_irq values. So after assigning the value of 2 to this link_irq variable the problem solved. I want to your help at two path; firstly why should I take this error. Secondly what is the role of the link_irq variable, what is the situations which are trigger to increase the link_irq variable and is the real reason of this problem the link_irq variable or anything else under this mechanism?
