The "goto chip_reset" is a bit misleading, because it does not actually issue a chip reset. Instead it is bypassing processing of other interrupts and assumes that the tasklet will issue a chip reset.
In the case of RXORN this does not happen, so bypassing processing of other interrupts will simply allow them to fire again. Even if RXORN was triggering a reset, it is not critical enough to need the bypass here.
