Since commit e22979d96a5 (mlx4_en: Moving to Interrupts for TX
completions), we no longer can free TX skb from hard IRQ, but only from
normal softirq or process context.
Therefore, we can directly call dev_kfree_skb() from
mlx4_en_free_tx_desc() like other conventional NAPI drivers.
Hi Eric,
At the moment the TX completion processing is done from IRQ context.
So I think we need to change the driver to work with NAPI for TX completions
before making this change.
I'll send the patch in a few days.
