As RTNL is held while doing tunnels inserts and deletes, we can remove ipip_lock spinlock. My initial RCU conversion was conservative and converted the rwlock to spinlock, with no RTNL requirement. Use appropriate rcu annotations and modern lockdep checks as well. Signed-off-by:

We sometime want to dereference an rcu protected pointer while holding RTNL. Use a macro to hide all lockdep details. Signed-off-by:

struct ethtool_rawip4_spec and struct ethtool_ether_spec are neither commented nor used by any driver, so remove them. Adjust padding in the user-visible unions that included these structures. Fix references to struct ethtool_rawip4_spec in ethtool_get_rx_ntuple(), which should use struct ethtool_usrip4_spec. struct ethtool_usrip4_spec cannot hold IPv6 host addresses and there is no separate structure that can, so remove ETH_RX_NFC_IP6 and the reference to it in niu.

There are now several interfaces within the ethtool API for getting and setting RX flow filtering and hashing behaviour, most of which are poorly documented. This adds kernel-doc comments for all these interfaces, based on the existing incomplete comments and on the initial implementations. Signed-off-by:

The tg3's phy routines define temporary variables in many locations within the same routine. This patch unifies all temporary variables into one location. Reviewed-by:

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. Reviewed-by:

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:
