I agree. Not a priority, at all.

I could look into this tomorrow.

I noticed, for example these 3 in the same function:
struct wid strWIDList[8];
u32 u32WidsCount = 0, dummyval = 0;
u8 *pu8CurrByte = NULL;

Not pretty and cleaning those should take little time.

Switching memcpy for ether_addr_copy and memcmp for ether_addr_equal.

I could send a patch for this as well, but I would need to have somebody
test it for me. Or maybe get this hardware for myself and do it properly.

Do you approve of my original patch?

Thanks for the review :)
