From 3007b05df4301aad179acc6ca1c3645785576df6 Mon Sep 17 00:00:00 2001

Subject: gro: fix napi_gro_frags() Fast GRO breakage due to IP
alignment check
Commit 7ad18ff6449cbd6beb26b53128ddf56d2685aa93 upstream.
Commit 38ec4944b593 ("gro: ensure frag0 meets IP header alignment")
did the right thing, but missed the fact that napi_gro_frags() logics
calls for skb_gro_reset_offset() *before* pulling Ethernet header
to the skb linear space.
That said, the introduced check for frag0 address being aligned to 4
always fails for it as Ethernet header is obviously 14 bytes long,
and in case with NET_IP_ALIGN its start is not aligned to 4.
Fix this by adding @nhoff argument to skb_gro_reset_offset() which
tells if an IP header is placed right at the start of frag0 or not.
This restores Fast GRO for napi_gro_frags() that became very slow
after the mentioned commit, and preserves the introduced check to
avoid silent unaligned accesses.
From v1 [0]:
- inline tiny skb_gro_reset_offset() to let the code be optimized
more efficively (esp. for the !NET_IP_ALIGN case) (Eric);
- pull in Reviewed-by from Eric.

Subject: [RFC net-next 7/7] net: dsa: mv88e6xxx: Request assisted learning on CPU port
Date: Sat, 16 Jan 2021 02:25:15 +0100
Archived-At: <https://lore.kernel.org/netdev/20210116012515.3152-8-tobias@waldekranz.com/>
While the hardware is capable of performing learning on the CPU port,
it requires alot of additions to the bridge's forwarding path in order
to handle multi-destination traffic correctly.
Until that is in place, opt for the next best thing and let DSA sync
the relevant addresses down to the hardware FDB.
