Yes, our work included ethernet support for the LS1046 by heavily
modifying the sys/dev/dpaa driver, used by PowerPC QorIQ line. As the
work was done on 11.x, nice forward port here is a challenge, we
currently have no free cycles for.

Anyway, LS2K uses a different IP (DPAA2) - even though it has some
common components with the DPAA, there's a certain amount of work to
be done. In case someone has spare funds for this, please contact me
directly :)

Best regards,
