Now that each NAPI instance has its own producer ring, it no longer makes sense to keep the producer ring structure external. This patch migrates the producer ring struct to tg3_napi and pivots the code to the new implementation.

TG3_IRQ_MAX_VECS should be seen as the maximum number of vectors that any device could be expected to use. tp->irq_max represents the maximum number of vectors the current device can use. This patch clarifies the semantics of the code to match the above description.

This patch adjusts the driver to use the tg3_start_xmit_dma_bug() transmit routine for all revisions of 5717 asic rev devices and then allows the driver to attach to B0 and later devices.

NCSI firmware does not accept APE events. It relies on a "driver state" location in shared memory to tell it what the driver's current state is. This patch pivots the code to use the new driver state scheme.

Earlier versions of tg3 devices had a problem where the read DMA FIFO could be overrun in certain edge conditions. The fix was to limit the number of rx BDs the hardware would fetch at a time. For later devices (5761, 5784 and later ASIC revs), there is a hardware fix that must be enabled to fix the same problem. This patch adds that hardware fix. There is a gap in the ASIC revision lineage where neither fix is applied. This is intentional as these ASIC revisions are not afflicted by the bug.

The code is quite convoluted, simplify it. This also avoids calling e1000_request_irq() without testing the value it returned, which was bad.

In preparation for changes to the way channels and queue structures are allocated, revise the macros and functions used to look up and iterator over them. - Replace efx_for_each_tx_queue() with iteration over channels then TX queues - Replace efx_for_each_rx_queue() with iteration over channels then RX queues (with one exception, shortly to be removed) - Introduce efx_get_{channel,rx_queue,tx_queue}() functions to look up channels and queues by index - Introduce efx_channel_get_{rx,tx}_queue() functions to look up a channel's queues Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

Currently we allocate DMA descriptor rings and event rings using pci_alloc_consistent() which selects non-blocking behaviour from the page allocator (GFP_ATOMIC). This is unnecessary, and since we currently allocate a single contiguous block for each ring (up to 32 pages!) these allocations are likely to fail if there is any significant memory pressure. Use dma_alloc_coherent() and GFP_KERNEL instead. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

rx_over_errors appears to be intended as a count of packets that overflow a packet buffer in the NIC. Given that we implement a cut-through receive path, this should always be 0. rx_dropped appears to be the correct counter for packets dropped due to lack of host buffers.
