net: mvneta: improve suspend/resume
Current suspend/resume implementation reuses the mvneta_open() and mvneta_close(), but it could be optimized to take only necessary actions during suspend/resume. One obvious problem of current implementation is: after hundreds of system suspend/resume cycles, the resume of mvneta could fail due to fragmented dma coherent memory. After this patch, the non-necessary memory alloc/free is optimized out. Signed-off-by: Jisheng Zhang <Jisheng.Zhang@synaptics.com> Signed-off-by: David S. Miller <davem@davemloft.net>
