From 6cee96e09df54ae17784c0f38a49e0ed8229b825 Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Thu, 8 Dec 2022 20:01:21 +0800 Subject: ethernet: s2io: don't call dev_kfree_skb() under spin_lock_irqsave() It is not allowed to call kfree_skb() or consume_skb() from hardware interrupt context or with hardware interrupts being disabled. It should use dev_kfree_skb_irq() or dev_consume_skb_irq() instead. The difference between them is free reason, dev_kfree_skb_irq() means the SKB is dropped in error and dev_consume_skb_irq() means the SKB is consumed in normal. In this case, dev_kfree_skb() is called in free_tx_buffers() to drop the SKBs in tx buffers, when the card is down, so replace it with dev_kfree_skb_irq() here.
