ipq40xx: 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.
