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. Reviewed-by:

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. Reviewed-by:

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. Reviewed-by:

It was recently discovered that enabling TSS can lockup the device. This patch disables the feature until a suitable workaround can be found. Signed-off-by:

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. Reviewed-by:

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

Default number of rx buffers will be divided equally between allocated queues. This will decrease amount of pre-allocated buffers on systems with multiple CPUs. User can override this behavior with ethtool -G. Minimum amount of rx buffers per queue set to 128. Reported-by:

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: -

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:

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. Signed-off-by:

Calculating rx_bad as rx_packets - rx_good is unnecessary and incorrect, since rx_good does not include control frames (e.g. pause frames) and rx_packets does. Signed-off-by:
