Subject: kernel/modules: relocate teql hotplug from iproute2 to kmod-sched
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0d5e308664ee2ee449e19d10d19427a4ea0dae4b;p=openwrt%2Fstaging%2Fadrian.git

kernel/modules: relocate teql hotplug from iproute2 to kmod-sched

The link equalizer sch_teql.ko of package kmod-sched relies on a hotplug
script historically included in iproute2's tc package. In previous
discussion [1], consensus was the hotplug script is best located together
with the module in kmod-sched, but this change was deferred at the time.

Relocate the hotplug script now. This change also simplifies adding a tc
variant for minimal size with reduced functionality.
