Subject: net_sched: copy exts->type in tcf_exts_change()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5301e3e117d88ef0967ce278912e54757f1a31a2;p=linux-beck.git

net_sched: copy exts->type in tcf_exts_change()

We need to copy exts->type when committing the change, otherwise
it would be always 0. This is a quick fix for -net and -stable,
for net-next tcf_exts will be removed.

Fixes: commit 33be627159913b094bb578e83 ("net_sched: act: use standard struct list_head")
