2011-11-17net: Add ethtool to mii advertisment conversion helpersMatt Carlson6-120/+197
Translating between ethtool advertisement settings and MII advertisements are common operations for ethernet drivers. This patch adds a set of helper functions that implements the conversion. The patch then modifies a couple of the drivers to use the new functions. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2011-11-14IPv6 routing, NLM_F_* flag support: REPLACE and EXCL flags support, warn ↵Matti Vaittinen1-15/+94
about missing CREATE flag The support for NLM_F_* flags at IPv6 routing requests. If NLM_F_CREATE flag is not defined for RTM_NEWROUTE request, warning is printed, but no error is returned. Instead new route is added. Later NLM_F_CREATE may be required for new route creation. Exception is when NLM_F_REPLACE flag is given without NLM_F_CREATE, and no matching route is found. In this case it should be safe to assume that the request issuer is familiar with NLM_F_* flags, and does really not want route to be created. Specifying NLM_F_REPLACE flag will now make the kernel to search for matching route, and replace it with new one. If no route is found and NLM_F_CREATE is specified as well, then new route is created. Also, specifying NLM_F_EXCL will yield returning of error if matching route is found.

2011-11-14bnx2x: uses build_skb() in receive pathEric Dumazet5-169/+171
bnx2x uses following formula to compute its rx_buf_sz : dev->mtu + 2*L1_CACHE_BYTES + 14 + 8 + 8 + 2 Then core network adds NET_SKB_PAD and SKB_DATA_ALIGN(sizeof(struct skb_shared_info)) Final allocated size for skb head on x86_64 (L1_CACHE_BYTES = 64, MTU=1500) : 2112 bytes : SLUB/SLAB round this to 4096 bytes. Since skb truesize is then bigger than SK_MEM_QUANTUM, we have lot of false sharing because of mem_reclaim in UDP stack. One possible way to half truesize is to reduce the need by 64 bytes (2112 -> 2048 bytes) Instead of allocating a full cache line at the end of packet for alignment, we can use the fact that skb_shared_info sits at the end of skb->head, and we can use this room, if we convert bnx2x to new build_skb() infrastructure. skb_shared_info will be initialized after hardware finished its transfert, so we can eventually overwrite the final padding. Using build_skb() also reduces cache line misses in the driver, since we use cache hot skb instead of cold ones. Number of in-flight sk_buff structures is lower, they are recycled while still hot.

2011-11-14net: introduce build_skb()Eric Dumazet2-0/+50
One of the thing we discussed during netdev 2011 conference was the idea to change some network drivers to allocate/populate their skb at RX completion time, right before feeding the skb to network stack. In old days, we allocated skbs when populating the RX ring. This means bringing into cpu cache sk_buff and skb_shared_info cache lines (since we clear/initialize them), then 'queue' skb->data to NIC. By the time NIC fills a frame in skb->data buffer and host can process it, cpu probably threw away the cache lines from its caches, because lot of things happened between the allocation and final use. So the deal would be to allocate only the data buffer for the NIC to populate its RX ring buffer. And use build_skb() at RX completion to attach a data buffer (now filled with an ethernet frame) to a new skb, initialize the skb_shared_info portion, and give the hot skb to network stack. build_skb() is the function to allocate an skb, caller providing the data buffer that should be attached to it. Drivers are expected to call skb_reserve() right after build_skb() to adjust skb->data to the Ethernet frame (usually skipping NET_SKB_PAD and NET_IP_ALIGN, but some drivers might add a hardware provided alignment) Data provided to build_skb() MUST have been allocated by a prior kmalloc() call, with enough room to add SKB_DATA_ALIGN(sizeof(struct skb_shared_info)) bytes at the end of the data without corrupting incoming frame. data = kmalloc(NET_SKB_PAD + NET_IP_ALIGN + 1536 + SKB_DATA_ALIGN(sizeof(struct skb_shared_info)), GFP_ATOMIC); ... skb = build_skb(data); if (!skb) { recycle_data(data); } else { skb_reserve(skb, NET_SKB_PAD + NET_IP_ALIGN); ... } Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Eilon Greenstein <eilong@broadcom.com> CC: Ben Hutchings <bhutchings@solarflare.com> CC: Tom Herbert <therbert@google.com> CC: Jamal Hadi Salim <hadi@mojatatu.com> CC: Stephen Hemminger <shemminger@vyatta.com> CC: Thomas Graf <tgraf@infradead.org> CC: Herbert Xu <herbert@gondor.apana.org.au> CC: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.
