I think the 0x0A is pointless and should not be included here. If the
register does not contain 0x0A, the device does not follow the open
alliance standard, and hence the lower part of the register is
meaningless.

This is why i suggested -ENODEV should actually be returned on invalid
values in this register.

Building with W=1 C=2 will tell you about kerneldoc issues. Ideally we
want all network code to be clean with these two options.
