From: Alexander Duyck Date: Fri, 1 May 2015 17:34:44 +0000 (-0700) Subject: r8169: Do not use dev_kfree_skb in xmit path X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=eb781397904e5d6b90c80463eaa9dc592831bdae;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git r8169: Do not use dev_kfree_skb in xmit path The function r8169_csum_workaround is called in the ndo_start_xmit path of the r8169 driver. As such it should not be using dev_kfree_skb as it is not irq safe, so instead we should be using dev_kfree_skb_any for freeing in the dropped path, and dev_consume_skb_any for any frames that were transmitted.
