[linux-sparc-users] why can't I connect to a SPARC Linux LDOM via IPv6?

[Alexandre Chartre]

ethtool commands are not persistent upon reboot, so you will an RC script.

If you use /etc/sysconfig/network-scripts/ifcfg-eth0 then you can specify
ethtool options in ETHTOOL_OPTS, e.g.:

ETHTOOL_OPTS="tx-checksum-ip-generic off"

That's regardless of the OS that I'm coming from...although I _can_ ssh back locally to the (either global or link-level) IPv6 address.
