* sfc: Update hardware definitions for SienaBen Hutchings2009-10-24
| | | | | | | | | | | | | Siena is still based on the Falcon hardware architecture and will share many of these definitions, so replace falcon_hwdefs.h with regs.h. The new definitions have been generated according to a naming convention which incorporates the type and revision information. Update the code accordingly.

* sfc: Move RX data FIFO thresholds out of struct efx_nic_typeBen Hutchings2009-10-24
| | | | | | | | | Since there are now separate blocks of code to set the thresholds for each NIC type, it is no longer useful to include them in the NIC type description. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* sfc: Remove versioned bitfield macrosBen Hutchings2009-10-24
| | | | | | | | | | | | | | | | | | These macros are not extensible to more than two NIC types without repetition of register definitions, and they are only used to deal with a few fields in RX_CFG_REG and global events which moved between Falcon rev A1 and B0. Therefore: - Move RX_CFG_REG initialisation into its own function which tests the NIC revision just once - Explicitly test the NIC revision when checking the RX_RECOVERY flag in global events - Merge definitions of RX_XOFF_MAC_EN flag, which did not move - Remove the macro definitions Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

* net: Use sk_tx_queue_mapping for connected socketsKrishna Kumar2009-10-20
| | | | | | | | | | | For connected sockets, the first run of dev_pick_tx saves the calculated txq in sk_tx_queue_mapping. This is not saved if either the device has a queue select or the socket is not connected. Next iterations of dev_pick_tx uses the cached value of sk_tx_queue_mapping.

* net: Fix for dst_negative_adviceKrishna Kumar2009-10-20
| | | | | | | | | | | | | dst_negative_advice() should check for changed dst and reset sk_tx_queue_mapping accordingly. Pass sock to the callers of dst_negative_advice. (sk_reset_txq is defined just for use by dst_negative_advice. The only way I could find to get around this is to move dst_negative_() from dst.h to dst.c, include sock.h in dst.c, etc) Signed-off-by: Krishna Kumar <krkumar2@in.ibm.com> Signed-off-by: David S.

* net: Introduce sk_tx_queue_mappingKrishna Kumar2009-10-20
| | | | | | | | | | | | Introduce sk_tx_queue_mapping; and functions that set, test and get this value. Reset sk_tx_queue_mapping to -1 whenever the dst cache is set/reset, and in socket alloc. Setting txq to -1 and using valid txq=<0 to n-1> allows the tx path to use the value of sk_tx_queue_mapping directly instead of subtracting 1 on every tx.

* filter: Add SKF_AD_QUEUE instructionEric Dumazet2009-10-20
| | | | | | | | | | | | | It can help being able to filter packets on their queue_mapping. If filter performance is not good, we could add a "numqueue" field in struct packet_type, so that netif_nit_deliver() and other functions can directly ignore packets with not expected queue number. Lets experiment this simple filter extension first. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* af_packet: Avoid cache line dirtyingEric Dumazet2009-10-20
| | | | | | | | | | | | | | | | While doing multiple captures, I found af_packet was dirtying cache line containing its prot_hook. This slow down machines where several cpus are necessary to handle capture traffic, as each prot_hook is traversed for each packet coming in or out the host. This patches moves "struct packet_type prot_hook" to the end of packet_sock, and uses a ____cacheline_aligned_in_smp to make sure this remains shared by all cpus.

* can: provide library functions for skb allocationWolfgang Grandegger2009-10-20
| | | | | | | | | | | | | | | | | | | | | | This patch makes the private functions alloc_can_skb() and alloc_can_err_skb() of the at91_can driver public and adapts all drivers to use these. While making the patch I realized, that the skb's are *not* setup consistently. It's now done as shown below: skb->protocol = htons(ETH_P_CAN); skb->pkt_type = PACKET_BROADCAST; skb->ip_summed = CHECKSUM_UNNECESSARY; *cf = (struct can_frame *)skb_put(skb, sizeof(struct can_frame)); memset(*cf, 0, sizeof(struct can_frame)); The frame is zeroed out to avoid uninitialized data to be passed to user space. Some drivers or library code did not set "pkt_type" or "ip_summed". Also, "__constant_htons()" should not be used for runtime invocations, as pointed out by David Miller.

* inet: rename some inet_sock fieldsEric Dumazet2009-10-18
| | | | | | | | | | | | | | | | In order to have better cache layouts of struct sock (separate zones for rx/tx paths), we need this preliminary patch. Goal is to transfert fields used at lookup time in the first read-mostly cache line (inside struct sock_common) and move sk_refcnt to a separate cache line (only written by rx path) This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr, sport and id fields. This allows a future patch to define these fields as macros, like sk_refcnt, without name clashes. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
