Add unicast steering entries to resource tracker. Do qp_detach also for these entries when VF doesn't shut down gracefully. Otherwise there is leakage of these resources, since they are not tracked. Signed-off-by:

When adding new unicast steer entry, before moving qp to state ready, actually before calling mlx4_RST2INIT_QP_wrapper(), there were added a lot of entries with local_qpn=0 into radix tree. This fact impacted the get_res() function and proper functioning of resource tracker in addition to adding trash entries into radix tree. Signed-off-by:

When passing MLX4_UC_STEER=1 it was translated to value 2 after mlx4_QP_ATTACH_wrapper. Therefore in new_steering_entry() unicast steer entries were added to index 2 of array of size 2. Fixing this bug by shift right to one position. Signed-off-by:

Jean Delvare reported bonding on top of 3c59x adapters was not detecting network cable removal fast enough. 3c59x indeed uses a 60 seconds timer to check link status if carrier is on, and 5 seconds if carrier is off. This patch reduces timer period to 5 seconds if device is a bonding slave. Reported-by:

This commit ensures that lost_cnt_hint is correctly updated in tcp_shifted_skb() for FACK TCP senders. The lost_cnt_hint adjustment in tcp_sacktag_one() only applies to non-FACK senders, so FACK senders need their own adjustment. This applies the spirit of 1e5289e1 - except now that the sequence range passed into tcp_sacktag_one() is correct we need only have a special case adjustment for FACK. Signed-off-by:

Commit "391420f7: fec: use an unique MDIO bus name" first modified the MDIO bus name to include the platform name, then in commit "a7ed07d5: net: fec: correct phy_name buffer length when init phy_name" the PHY name formatting was fixed in the case the PHY matches a PHY driver. The FEC driver however, also handles the case where we want to attach to the fixed MDIO bus name, which was previously named "0", and now "fixed-0".

Commit 3e617506: bcm63xx_enet: use an unique MDIO bus name introduced a regression in the PHY connection logic, since the PHY name was formatted to expect the bus name to be "0" or "1", whereas it is now "bcm63xx-enet-0" or "bcm63xx-enet-1". Reported-by:

Fix the newly-SACKed range to be the range of newly-shifted bytes. Previously - since 832d11c5 - tcp_shifted_skb() incorrectly called tcp_sacktag_one() with the start and end sequence numbers of the skb it passes in set to the range just beyond the range that is newly-SACKed. This commit also removes a special-case adjustment to lost_cnt_hint in tcp_shifted_skb() since the pre-existing adjustment of lost_cnt_hint in tcp_sacktag_one() now properly handles this things now that the correct start sequence number is passed in.

This commit allows callers of tcp_sacktag_one() to pass in sequence ranges that do not align with skb boundaries, as tcp_shifted_skb() needs to do in an upcoming fix in this patch series. In fact, now tcp_sacktag_one() does not need to depend on an input skb at all, which makes its semantics and dependencies more clear. Signed-off-by:

Quoth David: 1) GRO MAC header comparisons were ethernet specific, breaking other link types. This required a multi-faceted fix to cure the originally noted case (Infiniband), because IPoIB was lying about it's actual hard header length. Thanks to Eric Dumazet, Roland Dreier, and others. 2) Fix build failure when INET_UDP_DIAG is built in and ipv6 is modular. From Anisse Astier. 3) Off by ones and other bug fixes in netprio_cgroup from Neil Horman. 4) ipv4 TCP reset generation needs to respect any network interface binding from the socket, otherwise route lookups might give a different result than all the other segments received. From Shawn Lu. 5) Fix unintended regression in ipv4 proxy ARP responses, from Thomas Graf. 6) Fix SKB under-allocation bug in sh_eth, from Yoshihiro Shimoda. 7) Revert skge PCI mapping changes that are causing crashes for some folks, from Stephen Hemminger. 8) IPV4 route lookups fill in the wildcarded fields of the given flow lookup key passed in, which is fine most of the time as this is exactly what the caller's want. However there are a few cases that want to retain the original flow key values afterwards, so handle those cases properly. Fix from Julian Anastasov. 9) IGB/IXGBE VF lookup bug fixes from Greg Rose. 10) Properly null terminate filename passed to ethtool flash device method, from Ben Hutchings. 11) S3 resume fix in via-velocity from David Lv. 12) Fix double SKB free during xmit failure in CAIF, from Dmitry Tarnyagin. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (72 commits) net: Don't proxy arp respond if iif == rt->dst.dev if private VLAN is disabled ipv4: Fix wrong order of ip_rt_get_source() and update iph->daddr. netprio_cgroup: fix wrong memory access when NETPRIO_CGROUP=m netprio_cgroup: don't allocate prio table when a device is registered netprio_cgroup: fix an off-by-one bug bna: fix error handling of bnad_get_flash_partition_by_offset() isdn: type bug in isdn_net_header() net: Make qdisc_skb_cb upper size bound explicit. ixgbe: ethtool: stats user buffer overrun ixgbe: dcb: up2tc mapping lost on disable/enable CEE DCB state ixgbe: do not update real num queues when netdev is going away ixgbe: Fix broken dependency on MAX_SKB_FRAGS being related to page size ixgbe: Fix case of Tx Hang in PF with 32 VFs ixgbe: fix vf lookup igb: fix vf lookup e1000: add dropped DMA receive enable back in for WoL gro: more generic L2 header check IPoIB: Stop lying about hard_header_len and use skb->cb to stash LL addresses zd1211rw: firmware needs duration_id set to zero for non-pspoll frames net: enable TC35815 for MIPS again ... -

Commit 653241 (net: RFC3069, private VLAN proxy arp support) changed the behavior of arp proxy to send arp replies back out on the interface the request came in even if the private VLAN feature is disabled. Previously we checked rt->dst.dev != skb->dev for in scenarios, when proxy arp is enabled on for the netdevice and also when individual proxy neighbour entries have been added. This patch adds the check back for the pneigh_lookup() scenario. Signed-off-by:
