Subject: [BRIDGE]: receive path optimization
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7ce54e3f428b33af714271140601c87b8bf2c544;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[BRIDGE]: receive path optimization

This improves the bridge local receive path by avoiding going
through another softirq.  The bridge receive path is already being called
from a netif_receive_skb() there is no point in going through another
receiveq round trip.

Recursion is limited because bridge can never be a port of a bridge
so handle_bridge() always returns.
