Subject: [LLC]: Use skb_reset_mac_header in llc_alloc_frame
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0a1b0ad9ae27f918fd935c6da101083e11446f09;p=openwrt%2Fstaging%2Fblogic.git

[LLC]: Use skb_reset_mac_header in llc_alloc_frame

skb->head is equal to skb->data after alloc_skb, so reset the mac header while
this is true, i.e. before skb_reserve.
