The previous default of per-package can be more CPU-efficient, but users generally seem to prefer per-core. It should also allow accelerated RFS to direct packets more precisely, if IRQ affinity is properly spread out. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

This ensures a linear behaviour when filling /proc/net/if_inet6 thus making ifconfig run really fast on IPv6 only addresses. In fact, with this patch and the IPv4 one sent a while ago, ifconfig will run in linear time regardless of address type. IPv4 related patch: f04565dd dev: use name hash for dev_seq_ops ...

Recently Dave noticed that a test we did in ipv6_add_addr to see if we next hop route for the interface we're adding an addres to was wrong (see commit 7ffbcecb). for one, it never triggers, and two, it was completely wrong to begin with. This test was meant to cover this section of RFC 4429: 3.3 Modifications to RFC 2462 Stateless Address Autoconfiguration * (modifies section 5.5) A host MAY choose to configure a new address as an Optimistic Address. A host that does not know the SLLAO of its router SHOULD NOT configure a new address as Optimistic. A router SHOULD NOT configure an Optimistic Address. This patch should bring us into proper compliance with the above clause. Since we only add a SLAAC address after we've received a RA which may or may not contain a source link layer address option, we can pass a pointer to that option to addrconf_prefix_rcv (which may be null if the option is not present), and only set the optimistic flag if the option was found in the RA. Change notes: (v2) modified the new parameter to addrconf_prefix_rcv to be a bool rather than a pointer to make its use more clear as per request from davem.

SFQ q->perturbation is used in sfq_hash() as an input to Jenkins hash. We currently randomize this 32bit value only if a perturbation timer is setup.

Define special location values for RX NFC that request the driver to select the actual rule location. This allows for implementation on devices that use hash-based filter lookup, whereas currently the API is more suited to devices with TCAM lookup or linear search. In ethtool_set_rxnfc() and the compat wrapper ethtool_ioctl(), copy the structure back to user-space after insertion so that the actual location is returned.

SMSC LAN generation 4 chips integrate an IEEE 802.3 ethernet physical layer. The PHY driver for this integrated chip enable an energy detect power-down mode. When the PHY is in a power-down mode, it prevents the MAC portion chip to be software reseted. That means that if we compile the kernel with the configuration option SMSC_PHY enabled and try to bring the network interface up without an cable plug-ed the PHY will be in a low power mode and the software reset will fail returning -EIO to user-space: root@igep00x0:~# ifconfig eth0 up ifconfig: SIOCSIFFLAGS: Input/output error This patch disable the energy detect power-down mode before trying to software reset the LAN chip and re-enables after it was reseted successfully.

The driver uses a shared pool for both rx and tx descriptors. During open it queues fixed number of 128 descriptors for receive packets. For each received packet it tries to queue another descriptor. If this fails the descriptor is lost for rx. The driver has no limitation on tx descriptors to use, so it can happen during a nmap / ping -f attack that the driver allocates all descriptors for tx and looses all rx descriptors. The driver stops working then. To fix this limit the number of tx descriptors used to half of the descriptors available, the rx path uses the other half. Tested on a custom board using nmap / ping -f to the board from two different hosts. Signed-off-by: NSascha Hauer <s.hauer@pengutronix.de> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

SFQ enqueue algo puts a new flow _behind_ all pre-existing flows in the circular list. In fact this is probably an old SFQ implementation bug. 100 Mbits = ~8333 full frames per second, or ~8 frames per ms. With 50 flows, it means your "new flow" will have to wait 50 packets being sent before its own packet. Thats the ~6ms. We certainly can change SFQ to give a priority advantage to new flows, so that next dequeued packet is taken from a new flow, not an old one.
