2010-09-13bnx2x: Spread rx buffers between allocated queuesDmitry Kravkov
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.

2010-09-10sfc: Allow changing the DMA ring sizes dynamically via ethtoolBen Hutchings

2010-09-10sfc: Make the dmaq size a run-time setting (rather than compile-time)Steve Hodgson

2010-09-10sfc: Allocate each channel separately, along with its RX and TX queuesBen Hutchings

2010-09-10sfc: Refactor channel and queue lookup and iterationBen Hutchings
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.

2010-09-10sfc: Allocate DMA and event rings using GFP_KERNELBen Hutchings
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>

2010-09-10sfc: Accumulate RX_NODESC_DROP count in rx_dropped, not rx_over_errorsBen Hutchings
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.

2010-09-10sfc: Use MCDI RX_BAD_FCS_PKTS count as MAC rx_bad countBen Hutchings
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: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-09-09ipheth: remove incorrect devtype to WWANDan Williams
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.

2010-09-09tipc: Optimize handling excess content on incoming messagesPaul Gortmaker
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.

2010-09-08udp: add rehash on connect()Eric Dumazet
commit 30fff923 introduced in linux-2.6.33 (udp: bind() optimisation) added a secondary hash on UDP, hashed on (local addr, local port). Problem is that following sequence : fd = socket(...) connect(fd, &remote, ...) not only selects remote end point (address and port), but also sets local address, while UDP stack stored in secondary hash table the socket while its local address was INADDR_ANY (or ipv6 equivalent) Sequence is : - autobind() : choose a random local port, insert socket in hash tables [while local address is INADDR_ANY] - connect() : set remote address and port, change local address to IP given by a route lookup. When an incoming UDP frame comes, if more than 10 sockets are found in primary hash table, we switch to secondary table, and fail to find socket because its local address changed. One solution to this problem is to rehash datagram socket if needed. We add a new rehash(struct socket *) method in "struct proto", and implement this method for UDP v4 & v6, using a common helper. This rehashing only takes care of secondary hash table, since primary hash (based on local port only) is not changed.
