SubjectRe: [PATCH] net: macb: Do not enable RX buffer used interrupt

Well, that may have been premature. We are seeing the RXUBR interrupt get
stuck asserted on Zynq hardware, and I failed to realize the driver clears
RXUBR already in macb_interrupt... Not enabling that interrupt keeps my
system responsive, but it's not the correct solution to this issue.
