Subject: net: sched: fix TCF_LAYER_LINK case in tcf_get_base_ptr
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d3303a65a00c94372ddab831570647488e6c06e2;p=openwrt%2Fstaging%2Fblogic.git

net: sched: fix TCF_LAYER_LINK case in tcf_get_base_ptr

TCF_LAYER_LINK and TCF_LAYER_NETWORK returned the same pointer as
skb->data points to the network header.
Use skb_mac_header instead.
