The interrupt mask register provides control over which possible interrupt events in the IEVENT register
are permitted to participate in generating hardware interrupts to the PIC. All implemented bits in this
register are R/W and cleared upon a hardware reset. If the corresponding bits in both the IEVENT and
IMASK registers are set, the PIC receives an interrupt (for each eTSEC these are grouped into transmit,
receive, and error/diagnostic interrupts). The interrupt signal remains asserted until either the IEVENT bit
is cleared, by writing a 1 to it, or by writing a 0 to the corresponding IMASK bit.

1 The filer has accepted a frame via a matching rule that the RQFCR[GPI] bit set.
The receive queue filer result is invalid, either because not enough time between frames was available to
find a matching rule, or no entry in the filer table could be matched.

Filed frame to invalid receive queue. This bit indicates that either the receive queue filer chose to DMA a
received frame to a disabled RxBD ring, or that no rule in the filer table could be matched.
