I think QLCNIC_ETHTOOL_REGS_VER needs to be changed, as you appear to be
dumping more registers from the existing hardware as well.

So you removed the body of qlcnic_set_channels() in an earlier patch,
and now you're moving it and putting the body back how it was... Please
clean up the patch series so it doesn't have noise like this in it.

Should be -EINVAL in the second error case (the device supports the
operation, but not the mode requested).
