Subject: amd-xgbe: Use napi_alloc_skb when allocating skb in softirq
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=385565a1f0d365793e1f90746237d508bfeef9af;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

amd-xgbe: Use napi_alloc_skb when allocating skb in softirq

Use the napi_alloc_skb function to allocate an skb when running within
the softirq context to avoid calls to local_irq_save/restore.
