Type:struct sk_buff

If skb_shared - is the buffer shared*@skb: buffer to check* Returns true if more than one person has a reference to this* buffer. Then

1683

nskb = duplicate an sk_buff

1685

If Value is more likely to compile time(nskb) Then consume_skb(skb)

1687

Else free an sk_buff

1689

skb = nskb
