Implementing discard counters for the NIU driver turned out to be more complicated than first assumed. The discard counters for the NIU neptune chip are only 16-bit (even though this is a 64-bit chip). These 16-bit counters can overflow quickly, especially considering this is a 10Gbit/s ethernet card. The overflow indication bit is, unfortunatly, not usable as the counter value does not wrap, but remains at max value 0xFFFF. Resulting in lost counts until the counter is reset. The read and reset scheme also poses a problem. Both in theory and in practice counters can be lost in between reading nr64() and clearing the counter nw64(). For this reason, the number of counter clearings nw64() is limited/reduced. On the fast-path the counters are only syncronized once it exceeds 0x7FFF. When read by userspace, its syncronized fully.

This fixes a TX hang reported by Jesper Dangaard Brouer. When an architecutre cannot provide a fully functional 64-bit atomic readq/writeq, the driver must implement it's own. This is because only the driver can say whether doing something like using two 32-bit reads to implement the full 64-bit read will actually work properly. In particular one of the issues is whether the top 32-bits or the bottom 32-bits of the 64-bit register should be read first. There could be side effects, and in fact that is exactly the problem here. The TX_CS register has counters in the upper 32-bits and state bits in the lower 32-bits. A read clears the state bits. We would read the counter half before the state bit half. That first read would clear the state bits, and then the driver thinks that no interrupts are pending because the interrupt indication state bits are seen clear every time. Fix this by reading the bottom half before the upper half. Tested-by: NJesper Dangaard Brouer <jdb@comx.dk> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

It is possible for the TX ring to have packets sit in it for unbounded amounts of time. The only way to defer TX interrupts in the chip is to periodically set "mark" bits, when processing of a TX descriptor with the mark bit set is complete it triggers the interrupt for the TX queue's LDG. A consequence of this kind of scheme is that if packet flow suddenly stops, the remaining TX packets will just sit there. If this happens, since those packets could be charged to TCP socket send queues, such sockets could get stuck. The simplest solution is to divorce the socket ownership of the packet once the device takes the SKB, by using skb_orphan() in niu_start_xmit(). In hindsight, it would have been much nicer if the chip provided two interrupt sources for TX (like basically every other ethernet chip does). Namely, keep the "mark" bit, but also signal the LDG when the TX queue becomes completely empty. That way there is no need to have a deadlock breaker like this. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

niu_slowpath_interrupt() expects values to be setup in lp->{v0,v1,v2} but they aren't. That's only done by niu_schedule_napi() which is done later in the interrupt path. If niu_rx_error() returns zero, and v0 is clear, hit the RX_DMA_CTL_STATE register with a RX_DMA_CTL_STAT_MEX. Only emit verbose RX error logs if a fatal channel or port error is signalled. Other cases will be recorded into statistics by niu_log_rxchan_errors(). Signed-off-by: NDavid S. Miller <davem@davemloft.net>

I suggest the following instead, but I can unfortunately not do anything but build test it. Also, the driver does some other checks to make sure that PAGE_SIZE is a power of two (BUILD_BUG_ON() in niu_init()), doesn't seem like that could ever be untrue? Or are there really archs with non-power-of-two PAGE_SIZE? Signed-off-by: NOlof Johansson <olof@lixom.net> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
