stmmac: Discard masked flags in interrupt status register
DW GMAC databook says the following about bits in "Register 15 (Interrupt Mask Register)": --------------------------->8------------------------- When set, this bit __disables_the_assertion_of_the_interrupt_signal__ because of the setting of XXX bit in Register 14 (Interrupt Status Register). --------------------------->8------------------------- In fact even if we mask one bit in the mask register it doesn't prevent corresponding bit to appear in the status register, it only disables interrupt generation for corresponding event. 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.
