Daniel Hellstrom e1743a16a0 greth: moved TX ring cleaning to NAPI rx poll func ... This patch does not affect the 10/100 GRETH MAC. Before all GBit GRETH TX descriptor ring cleaning was done in start_xmit(), when descriptor list became full it activated TX interrupt to start the NAPI rx poll function to do TX ring cleaning. With this patch the TX descriptor ring is always cleaned from the NAPI rx poll function, triggered via TX or RX interrupt. Otherwise we could end up in TX frames being sent but not reported to the stack being sent. On the 10/100 GRETH this is not an issue since the SKB is copied&aligned into private buffers so that the SKB can be freed directly on start_xmit() Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> Signed-off-by: David S.
