Removed because in upstream*
  mvebu/patches-5.4/319-ARM-dts-turris-omnia-configure-LED-2--INTn-pin-as-interrupt-pin.patch

Manually rebased*
  generic/backport-5.4/700-v5.5-net-core-allow-fast-GRO-for-skbs-with-Ethernet-heade.patch

Added new backport*
  generic/backport-5.4/050-gro-fix-napi_gro_frags-Fast-GRO-breakage-due-to-IP-a.patch

All others updated automatically.

The new backport was included based on this[1] upstream commit that will be
mainlined soon.  This change is needed because Eric Dumazet's check for
NET_IP_ALIGN (landed in 5.4.114) causes huge slowdowns on drivers which use
napi_gro_frags().

Compile-tested on: x86/64, armvirt/64, ath79/generic
Runtime-tested on: x86/64, armvirt/64, ath79/generic

+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: [PATCH mvebu-dt] ARM: dts: turris-omnia: configure LED[2]/INTn pin as interrupt pin
-Date: Sun, 21 Feb 2021 00:11:44 +0100
-Message-Id: <20210220231144.32325-1-kabel@kernel.org>
-X-Mailer: git-send-email 2.26.2
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Use the `marvell,reg-init` DT property to configure the LED[2]/INTn pin
-of the Marvell 88E1514 ethernet PHY on Turris Omnia into interrupt mode.
-
-Without this the pin is by default in LED[2] mode, and the Marvell PHY
-driver configures LED[2] into "On - Link, Blink - Activity" mode.
-
-This fixes the issue where the pca9538 GPIO/interrupt controller (which
-can't mask interrupts in HW) received too many interrupts and after a
-time started ignoring the interrupt with error message:
-  IRQ 71: nobody cared
-
-There is a work in progress to have the Marvell PHY driver support
-parsing PHY LED nodes from OF and registering the LEDs as Linux LED
-class devices. Once this is done the PHY driver can also automatically
-set the pin into INTn mode if it does not find LED[2] in OF.
-
-Until then, though, we fix this via `marvell,reg-init` DT property.

-
-This patch fixes bug introduced with the commit that added Turris
-Omnia's DTS (26ca8b52d6e1), but will not apply cleanly because there is
-commit 8ee4a5f4f40d which changed node name and node compatible
-property and this commit did not go into stable.
-
-So either commit 8ee4a5f4f40d has also to go into stable before this, or
-this patch has to be fixed a little in order to apply to 4.14+.
-
-Please let me know how should I handle this.
