2009-08-05netxen: add hardware LRO supportDhananjay Phadke
Add support to handle aggregate packets from firmware. Local TCP flows are automatically identified by firmware based on the dest IP hash added by driver for local IP addresses. The packets are sent down on the jumbo rx ring. Signed-off-by: Narender Kumar <narender.kumar@qlogic.com> Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S.

2009-08-05netxen: remove unnecessary structuresDhananjay Phadke
Remove unnecessary offsetof calulations on these structures: netxen_board_info, netxen_user_old_info, netxen_new_user_info. The offsets into the flash are fixed, don't need to be calculated. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-08-05cpmac: wait longer after MDIO resetFlorian Fainelli
This patch slows down the MDIO_ALIVE busy waiting to let switches and PHY come up after reset. Previous loop was too quick for IC+175C and ADM6996C/L switches to come up. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-05cpmac: add support for fixed PHYFlorian Fainelli
This patch adds support for fixed PHY connected in MII mode to cpmac. We allow external and dumb_switch module parameters to override the PHY detection process since they are always connected with MDIO bus identifier 0. This lets fixed PHYs to be detected correctly and be connected to the their corresponding MDIO bus identifier. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: David S.

2009-08-02neigh: Convert garbage collection from softirq to workqueueEric Dumazet
Current neigh_periodic_timer() function is fired by timer IRQ, and scans one hash bucket each round (very litle work in fact) As we are supposed to scan whole hash table in 15 seconds, this means neigh_periodic_timer() can be fired very often. (depending on the number of concurrent hash entries we stored in this table) Converting this to a workqueue permits scanning whole table, minimizing icache pollution, and firing this work every 15 seconds, independantly of hash table size. This 15 seconds delay is not a hard number, as work is a deferrable one. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-07-30ixgbe: Fix RSC completion delay causing Rx interrupts to stopPeter P Waskiewicz Jr
When a user disables interrupt throttling with ethtool on 82599 devices, the interrupt timer may not be re-enabled if hardware RSC is running. The RSC completions in hardware don't complete before the next ITR event tries to fire, so the ITR timer never gets re-armed. This patch increases the amount of time between interrupts when throttling is disabled (rx-usecs = 0) when the hardware RSC deature is enabled.

2009-07-30xfrm: select sane defaults for xfrm[4|6] gc_threshNeil Horman
Choose saner defaults for xfrm[4|6] gc_thresh values on init Currently, the xfrm[4|6] code has hard-coded initial gc_thresh values (set to 1024). Given that the ipv4 and ipv6 routing caches are sized dynamically at boot time, the static selections can be non-sensical. This patch dynamically selects an appropriate gc threshold based on the corresponding main routing table size, using the assumption that we should in the worst case be able to handle as many connections as the routing table can. For ipv4, the maximum route cache size is 16 * the number of hash buckets in the route cache. Given that xfrm4 starts garbage collection at the gc_thresh and prevents new allocations at 2 * gc_thresh, we set gc_thresh to half the maximum route cache size. For ipv6, its a bit trickier. there is no maximum route cache size, but the ipv6 dst_ops gc_thresh is statically set to 1024. It seems sane to select a simmilar gc_thresh for the xfrm6 code that is half the number of hash buckets in the v6 route cache times 16 (like the v4 code does).

There is no reason for the arbitrary restriction that device must be up to create a vlan. This patch was added to Vyatta kernel to resolve startup ordering issues where vlan's are created but real device was disabled. Note: the vlan already correctly inherits the operstate from real device; so if vlan is created and real device is marked down, the vlan is marked down.
