Subject: net_sched actions: use nla_parse_nested()
X-Git-Url: http://git.cascardo.eti.br/?p=cascardo%2Flinux.git;a=commitdiff_plain;h=4700e9ce6ed8526a14e6cf9d7e319f675c16d0a7

net_sched actions: use nla_parse_nested()

Use nla_parse_nested instead of open-coding the call to
nla_parse() with the attribute data/len.
