Subject: bridge: Add br_netif_receive_skb remove netif_receive_skb_sk
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=04eb44890e5bb3cc855e5c0f18a05eb7311364b7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

bridge: Add br_netif_receive_skb remove netif_receive_skb_sk

netif_receive_skb_sk is only called once in the bridge code, replace
it with a bridge specific function that calls netif_receive_skb.
