Hi,
Dan reported a possible signedness issue on the pxa168_eth driver. While having a look at it, I came across a similar problem in the spider_net driver.
Here is one proposal to fix it. The first patch rework the spider_net_set_mac() function by removing the spider_net_get_mac_address() call and using memcpy() to set netdev->dev_addr (which is what's done in lots of Ethernet drivers) and the second one fix the actual signedness issue.
If for any reason you really want to keep a call to spider_net_get_mac_address() because the memcpy() is somehow not good enough here, we can also come up with a solution involving a temporary unsigned char variable.
I couldn't test these changes, so please do.
Thanks,
Antoine
