Subject: ibmveth: Call dev_consume_skb_any instead of dev_kfree_skb.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=26faa9d777718380c56419861370c3fe06a78c15;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ibmveth: Call dev_consume_skb_any instead of dev_kfree_skb.

Replace dev_kfree_skb with dev_consume_skb_any in ibmveth_start_xmit
that can be called in hard irq and other contexts.

In this code path the packet can have either been transmitted
or dropped, dev_consume_skb_any was choosen because that preserves
the existing semantics of the code, and a transmitted packet is
more likely.
