This patch reduce unecessary NETTX softirq call caused by free skb header. You will see this softirq comes twice while there is only one TX packet to be transmitted.
So using dev_kfree_skb() instead of dev_kfree_skb_any() to avoid this problem. Signed-off-by: Macpaul Lin <[email protected]> Cc: David S.
