Hi,
Currently mainline Linux is unusable on OCTEON II CN68XX SOCs due to
issues in Ethernet driver initialization. Some boards are hanging during
init, and all the needed register differences compared to the older SOCs
are not taken into account to make interrupts and packet delivery to work.
This patch set provides a minimal support to get octeon-ethernet going
on CN68XX. Tested on top of 4.2-rc6 with Cavium EBB6800 and Kontron
S1901 boards by sending traffic over XAUI interface with busybox.
You don't say how it was tested.
Does OCTEON and OCTEON II networking continue to function?
There is no SSO provisioning, so there will be limited buffering on
packet ingress. For low packet rates, it should be fine though.
