+From: Linus Walleij <linus.walleij@linaro.org>
+Date: Sat, 6 Jan 2024 01:12:22 +0100
+Subject: [PATCH 4/4] net: ethernet: cortina: Drop TSO support
+
+The recent change to allow large frames without hardware checksumming
+slotted in software checksumming in the driver if hardware could not
+do it.
+
+This will however upset TSO (TCP Segment Offloading). Typical
+error dumps includes this:
+
+skb len=2961 headroom=222 headlen=66 tailroom=0
+(...)
+WARNING: CPU: 0 PID: 956 at net/core/dev.c:3259 skb_warn_bad_offload+0x7c/0x108
+gemini-ethernet-port: caps=(0x0000010000154813, 0x00002007ffdd7889)
+
+And the packets do not go through.
+
+The TSO implementation is bogus: a TSO enabled driver must propagate
+the skb_shinfo(skb)->gso_size value to the TSO engine on the NIC.
+
+Drop the size check and TSO offloading features for now: this
+needs to be fixed up properly.
+
+After this ethernet works fine on Gemini devices with a direct connected
+PHY such as D-Link DNS-313.
+
+Also tested to still be working with a DSA switch using the Gemini
+ethernet as conduit interface.

+Subject: [PATCH 1/5] net: ethernet: cortina: Restore TSO support
+
+An earlier commit deleted the TSO support in the Cortina Gemini
+driver because the driver was confusing gso_size and MTU,
+probably because what the Linux kernel calls "gso_size" was
+called "MTU" in the datasheet.
+
+Restore the functionality properly reading the gso_size from
+the skbuff.
+
+Tested with iperf3, running a server on a different machine
+and client on the device with the cortina gemini ethernet:
+
+Connecting to host 192.168.1.2, port 5201
+60008000.ethernet-port eth0: segment offloading mss = 05ea len=1c8a
+60008000.ethernet-port eth0: segment offloading mss = 05ea len=1c8a
+60008000.ethernet-port eth0: segment offloading mss = 05ea len=27da
+60008000.ethernet-port eth0: segment offloading mss = 05ea len=0b92
+60008000.ethernet-port eth0: segment offloading mss = 05ea len=2bda
+(...)
+
+(The hardware MSS 0x05ea here includes the ethernet headers.)
+
+If I disable all segment offloading on the receiving host and
+dump packets using tcpdump -xx like this:
+
+ethtool -K enp2s0 gro off gso off tso off
+tcpdump -xx -i enp2s0 host 192.168.1.136
+
+I get segmented packages such as this when running iperf3:
+
+23:16:54.024139 IP OpenWrt.lan.59168 > Fecusia.targus-getdata1:
+Flags [.], seq 1486:2934, ack 1, win 4198,
+options [nop,nop,TS val 3886192908 ecr 3601341877], length 1448
+0x0000:  fc34 9701 a0c6 14d6 4da8 3c4f 0800 4500
+0x0010:  05dc 16a0 4000 4006 9aa1 c0a8 0188 c0a8
+0x0020:  0102 e720 1451 ff25 9822 4c52 29cf 8010
+0x0030:  1066 ac8c 0000 0101 080a e7a2 990c d6a8
+(...)
+0x05c0:  5e49 e109 fe8c 4617 5e18 7a82 7eae d647
+0x05d0:  e8ee ae64 dc88 c897 3f8a 07a4 3a33 6b1b
+0x05e0:  3501 a30f 2758 cc44 4b4a
+
+Several such packets often follow after each other verifying
+the segmentation into 0x05a8 (1448) byte packages also on the
+reveiving end. As can be seen, the ethernet frames are
+0x05ea (1514) in size.
+
+Performance with iperf3 before this patch: ~15.5 Mbit/s
+Performance with iperf3 after this patch: ~175 Mbit/s
+
+This was running a 60 second test (twice) the best measurement
+was 179 Mbit/s.
+
+For comparison if I run iperf3 with UDP I get around 1.05 Mbit/s
+both before and after this patch.
+
+While this is a gigabit ethernet interface, the CPU is a cheap
+D-Link DIR-685 router (based on the ARMv5 Faraday FA526 at
+~50 MHz), and the software is not supposed to drive traffic,
+as the device has a DSA chip, so this kind of numbers can be
+expected.

+Subject: [PATCH 2/5] net: ethernet: cortina: Use TSO also on common TCP
+
+It is possible to push the segment offloader to also
+process non-segmented frames: just pass the skb->len
+or desired MSS to the offloader and it will handle them.
+
+This is especially good if the user sets up the MTU
+and the frames get big, because the checksumming engine
+cannot handle any frames bigger than 1518 bytes, so
+segmenting them all to be at max that will be helpful
+for the hardware, which only need to quirk odd frames
+such as big UDP ping packets.
+
+The vendor driver always uses the TSO like this, and
+the driver seems more stable after this, so apparently
+the hardware may have been engineered to always use
+the TSO on anything it can handle.

+Subject: [PATCH] ARM: dts: Augment DIR-685 partition table for OpenWrt
+
+Rename the firmware partition so that the firmware MTD
+splitter will do its job, drop the rootfs arguments as
+the MTD splitter will set this up automatically.
