* drivers/net: Kill now superfluous ->last_rx stores.David S. Miller2008-11-03211-276/+1
| | | | | | | | | | | | | The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more. Some cases had to be skipped over because the drivers were making use of the ->last_rx value themselves. Signed-off-by: David S. Miller <davem@davemloft.net>

* net: '&' reduxAlexey Dobriyan2008-11-0338-509/+509
| | | | | | | | | | | | | I want to compile out proc_* and sysctl_* handlers totally and stub them to NULL depending on config options, however usage of & will prevent this, since taking adress of NULL pointer will break compilation. So, drop & in front of every ->proc_handler and every ->strategy handler, it was never needed in fact. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S.

* bonding, net: Move last_rx update into bonding recv logicJay Vosburgh2008-11-034-14/+24
| | | | | | | | | | | | | The only user of the net_device->last_rx field is bonding. This patch adds a conditional update of last_rx to the bonding special logic in skb_bond_should_drop, causing last_rx to only be updated when the ARP monitor is running. This frees network device drivers from the necessity of updating last_rx, which can have cache line thrash issues. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

* tg3: Refine power management and WOL codeMatt Carlson2008-11-031-17/+23
| | | | | | | | | | | | | | | | | | | | | Commit 12dac0756d357325b107fe6ec24921ec38661839 ("tg3: adapt tg3 to use reworked PCI PM code") introduced the new PCI PM API to the tg3 driver. The patch was understandably conservative, so this patch elaborates on that work. The patch starts by creating a single point in tg3_set_power_state() to decide whether or not to enable WOL. The rest of the code in tg3_set_power_state() was then pivoted to use the result of this decision. The patch then makes sure the device is allowed to wakeup before reporting whether or not WOL is currently enabled. The final hunks of the patch consolidate where the WOL capability and WOL enabled flags are set to a single location.

* tg3: Preserve DASH connectivity when WOL enabledMatt Carlson2008-11-032-1/+15
| | | | | | | | | | | | | | | | | | | | | DASH firmware runs on the APE side of the chip, but it requires a few MAC to be programmed correctly. When WOL is enabled and management firmware is disabled, incoming packets are evaluated and discarded at the chip's rule processor. When management firmware is enabled, the hardware must be informed that there are agents further up the stack that still use the incoming frames. Normally management firmware will configure the MAC correctly on its own, but there can be cases where the setting could get clobbered by the driver. The first hunk of this patch preserves this setting. The second hunk of this patch wipes out the driver present signature of the APE memory space. By doing so, the DASH firmware can assume driver absent behavior. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

| | | | | | | | | | | | | This patch replaces the existing APE register mapping code with a call to pci_ioremap_bar(). The code that maps the main device register space did not undergo a similar change because the information derived from the pci_resource_start() and pci_resource_len() is still used to populate the (optional) mem_start and mem_end netdevice members.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This eliminates the following often-generated warning from my 64 bit Opteron SMP test stand: eth0: too many iterations (6) in nv_nic_irq According to the web, the problem is that the forcedeth driver has a too-low value for max_interrupt_work. Grepping the kernel I see that forcedeth has the second lowest value of all ethernet drivers (ie, 6). Most are in the 20-40 range. So this patch increases this a bit, from 6 to 15 (at 15 forcedeth becomes the driver with third-lowest max_interrupt_work value). My test stand, which used to print out the above warnings repetitively whenever it was under heavy net load, no longer does so.

So, according to his suggestion, this patch removes classful options of netem. The main reason of this change is to remove ops->requeue() method, which is currently used only by netem.

Tunnel Mode SAs that Carry Initial and Non-Initial Fragments All implementations MUST support tunnel mode SAs that are configured to pass traffic without regard to port field (or ICMP type/code or Mobility Header type) values. If the SA will carry traffic for specified protocols, the selector set for the SA MUST specify the port fields (or ICMP type/code or Mobility Header type) as ANY. An SA defined in this fashion will carry all traffic including initial and non-initial fragments for the indicated Local/Remote addresses and specified Next Layer protocol(s)."
