But currently we expect a bit different behavior: status bits to be in sync with their masks, i.e. if mask for bit A is set in the mask register then bit A won't appear in the interrupt status register. This was proven to be incorrect assumption, see discussion here [1]. That misunderstanding causes unexpected behaviour of the GMAC, for example we were happy enough to just see bogus messages about link state changes. So from now on we'll be only checking bits that really may trigger an interrupt.
