I know, however it's completely impossible for us to run 2.6.x kernels, too many subtle changes are happening between new releases (ACPI routing, interrupt mitigation in e1000, NAPI, and other subsystems besides networking) and some features, like for example ipsec have changed fundamentally in the way they work with regard to filtering or packet traversal. We unfortunately don't have enough people to track and verify those changes regarding QA. A differnet point of view: I don't have the time nor do I get the money to change our firewall software to be compatible with 2.6.x kernels. Also some people's quest in trying to optimize latency (see RT threads on LKML) and tuning mm/* for smoother desktop performance has a negative tendancy on network server performance. Where would I best start to find out about differences between the 2.4.x and 2.6.x version of the tcp window tracking code? Do you remember when you stopped backporting fixes?
