Feng Tang 881d0327db net: alx: Work around the DMA RX overflow issue ... Commit 26c5f03 uses a new skb allocator to avoid the RFD overflow issue. But from debugging without datasheet, we found the error always happen when the DMA RX address is set to 0x....fc0, which is very likely to be a HW/silicon problem. So one idea is instead of adding a new allocator, why not just hitting the right target by avaiding the error-prone DMA address? This patch will actually * Remove the commit 26c5f03 * Apply rx skb with 64 bytes longer space, and if the allocated skb has a 0x...fc0 address, it will use skb_resever(skb, 64) to advance the address, so that the RX overflow can be avoided. In theory this method should also apply to atl1c driver, which I can't find anyone who can help to test on real devices.
