From: Dustin Marquess <redacted> Patch to disable the rx_copybreak feature on hardware architectures that don't allow unaligned DMA access. #ifdef code taken from tulip_core.c. Problem pointed out by Ivan Kokshaysky.
Color me confused but what are we trying to solve here ? The rx_copybreak processing is performed after the DMA from the network card to memory is done: DMA does not care about rx_copybreak. -- Ueimor
