Subject: [PATCH] bgmac: simplify rx DMA error handling Subject: [PATCH] bgmac: simplify rx DMA error handling
Unmap the DMA buffer before checking it. If it is poisoned, map it again Unmap the DMA buffer before checking it. If an error occurs, free the
and pass it back to the hardware. buffer and allocate a new one. If allocation or mapping fails, retry as
long as there is NAPI poll budget left (count every attempt instead of
every frame).
