net: netsec: remove loops in napi Rx process
netsec_process_rx was running in a loop trying to process as many packets as possible before re-enabling interrupts. With the recent DMA changes this is not needed anymore as we manage to consume all the budget without looping over the function. Since it has no performance penalty let's remove that and simplify the Rx path a bit Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: David S.
