net: skbuff: don't zero tc members when freeing skb
Not needed, only four cases: - kfree_skb (or one of its aliases). Don't need to zero, memory will be freed. - kfree_skb_partial and head was stolen: memory will be freed. - skb_morph: The skb header fields (including tc ones) will be copied over from the 'to-be-morphed' skb right after skb_release_head_state returns. - skb_segment: Same as before, all the skb header fields are copied over from the original skb right away. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>
