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.
