Meelis,

Yes, please revert that patch (it should never have deleted the calls to __constant_cpu_to_le16 (those fields are all LE in the HW/nvram)).

Since QLogic is still silent on this one, I will send it to you:

Revert change that breaks QLA2XXX on big-endian systems,
__constant_cpu_to_le16() is still needed.
