[OpenWrt-Devel] [L2TP] Bad UDP Checksum on TP-LINK hardware

2016-07-28 Thread Leon George
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Hi :-) The UDP checksum for outgoing L2TP datagrams seems to be broken. It has been tested with TP-LINK's WR842n, WDR3600, and WDR4300. On two normal Linux computers it's working. We've tried disabling UDP offloading using ethtool without success.
