Package: kernel-image-2.6.8-1-686
Version: 2.6.8-3
Severity: important
Kernel 2.6.8 sets TCP window scaling to 7. It doesn't work with many broken
routers including mine. It is possible to set
net.ipv4.tcp_default_win_scale = 0
in sysctl.conf, but I suggest to prepare the patch which restore old behaviour,
analogical to ECN bit patch.
