Thanks for the review
I think I starting to get the idea of what I need to be looking for.

I'm not really sure what you mean, do you mean I should change '|' to '||"?
like this
bHwError = (((*(priv->rxringtail)) & (0x00000fff)) == 4080) ||
(((*(priv->rxringtail)) & (0x04000000)) != 0) ||
(((*(priv->rxringtail)) & (0x08000000)) != 0) ||
(((~(*(priv->rxringtail))) & (0x10000000)) != 0) ||
(((~(*(priv->rxringtail))) & (0x20000000)) != 0);

Thanks for your help, I'm really trying to do better, I will have this fix up
tomorrow for another review.
