+Subject: essedma: Disable TCP segmentation offload for IPv6
+
+It was noticed that the the whole MAC can hang when transferring data from
+one ar40xx port (WAN ports) to the CPU and from the CPU back to another
+ar40xx port (LAN ports). The CPU was doing only NATing in that process.
+
+Usually, the problem first starts with a simple data corruption:
+
+  $ wget https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.4.0-amd64-netinst.iso -O /dev/null
+  ...
+  Connecting to saimei.ftp.acc.umu.se (saimei.ftp.acc.umu.se)|2001:6b0:19::138|:443... connected.
+  ...
+  Read  error at byte 48807936/352321536 (Decryption has failed.). Retrying.
+
+But after a short while, the whole MAC will stop to react. No traffic can
+be transported anymore from the CPU port from/to the AR40xx PHY/switch and
+the MAC has to be resetted.
