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:

Empty received URBs are currently counted as errors but the device sends them sometimes as part of regular traffic - so remove this check. Signed-off-by:

Allocate hash tables for every online cpus, not every possible ones. NUMA aware allocations. Dont use a full page on arches where PAGE_SIZE > 1024*sizeof(void *) misc: __percpu , __read_mostly, __cpuinit annotations flow_compare_t is just an "unsigned long" Signed-off-by:

This requires some reorganisation of channel setup and teardown to ensure that we can always roll-back a failed change. Based on work by Steve Hodgson <shodgson@solarflare.com> Signed-off-by:

This will allow for reallocation of channel structures and rings. Change module parameter separate_tx_channels to be read-only, since we now require its value to be constant. Signed-off-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:

The 'wwan' devtype is meant for devices that require preconfiguration and *every* time setup before the ethernet interface can be used, like cellular modems which require a series of setup commands on serial ports or other mechanisms before the ethernet interface will handle packets. As ipheth only requires one-per-hotplug pairing setup with no preconfiguration (like APN, phone #, etc) and the network interface is usable at any time after that initial setup, remove the incorrect devtype wwan.

Remove code that trimmed excess trailing info from incoming messages arriving over an Ethernet interface. TIPC now ignores the extra info while the message is being processed by the node, and only trims it off if the message is retransmitted to another node. (This latter step is done to ensure the extra info doesn't cause the sk_buff to exceed the outgoing interface's MTU limit.) The outgoing buffer is guaranteed to be linear. Signed-off-by:
