Subject: vmxnet3: use netdev_alloc_skb_ip_align
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0d735f13d8842d94ea8236baf12db3bea7daaf98;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

vmxnet3: use netdev_alloc_skb_ip_align

Use netdev_alloc_skb_align, rather than open code using dev_alloc_skb.
Change allocation at startup to use GFP_KERNEL.
