* igb: drop support for UDP hashing w/ RSSAlexander Duyck2010-07-05
| | | | | | | | | | | This change removes UDP from the supported protocols for RSS hashing. The reason for removing this protocol is because IP fragmentation was causing a network flow to be broken into two streams, one for fragmented, and one for non-fragmented and this in turn was causing out-of-order issues.

| * netfilter: nf_nat: support user-specified SNAT rules in LOCAL_INPatrick McHardy2010-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.34 introduced 'conntrack zones' to deal with cases where packets from multiple identical networks are handled by conntrack/NAT. Packets are looped through veth devices, during which they are NATed to private addresses, after which they can continue normally through the stack and possibly have NAT rules applied a second time. This works well, but is needlessly complicated for cases where only a single SNAT/DNAT mapping needs to be applied to these packets. In that case, all that needs to be done is to assign each network to a seperate zone and perform NAT as usual. However this doesn't work for packets destined for the machine performing NAT itself since its corrently not possible to configure SNAT mappings for the LOCAL_IN chain. This patch adds a new INPUT chain to the NAT table and changes the targets performing SNAT to be usable in that chain. Example usage with two identical networks (192.168.0.0/24) on eth0/eth1: iptables -t raw -A PREROUTING -i eth0 -j CT --zone 1 iptables -t raw -A PREROUTING -i eth0 -j MARK --set-mark 1 iptables -t raw -A PREROUTING -i eth1 -j CT --zone 2 iptabels -t raw -A PREROUTING -i eth1 -j MARK --set-mark 2 iptables -t nat -A INPUT -m mark --mark 1 -j NETMAP --to 10.0.0.0/24 iptables -t nat -A POSTROUTING -m mark --mark 1 -j NETMAP --to 10.0.0.0/24 iptables -t nat -A INPUT -m mark --mark 2 -j NETMAP --to 10.0.1.0/24 iptables -t nat -A POSTROUTING -m mark --mark 2 -j NETMAP --to 10.0.1.0/24 iptables -t raw -A PREROUTING -d 10.0.0.0/24 -j CT --zone 1 iptables -t raw -A OUTPUT -d 10.0.0.0/24 -j CT --zone 1 iptables -t raw -A PREROUTING -d 10.0.1.0/24 -j CT --zone 2 iptables -t raw -A OUTPUT -d 10.0.1.0/24 -j CT --zone 2 iptables -t nat -A PREROUTING -d 10.0.0.0/24 -j NETMAP --to 192.168.0.0/24 iptables -t nat -A OUTPUT -d 10.0.0.0/24 -j NETMAP --to 192.168.0.0/24 iptables -t nat -A PREROUTING -d 10.0.1.0/24 -j NETMAP --to 192.168.0.0/24 iptables -t nat -A OUTPUT -d 10.0.1.0/24 -j NETMAP --to 192.168.0.0/24 Signed-off-by: Patrick McHardy <kaber@trash.net>

* | igb: Use only a single Tx queue in SR-IOV modeGreg Rose2010-07-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 82576 expects the second rx queue in any pool to receive L2 switch loop back packets sent from the second tx queue in another pool. The 82576 VF driver does not enable the second rx queue so if the PF driver sends packets destined to a VF from its second tx queue then the VF driver will never see them. In SR-IOV mode limit the number of tx queues used by the PF driver to one. This patch fixes a bug reported in which the PF cannot communciate with the VF and should be considered for 2.6.34 stable.

* | x86: Drop CONFIG_MCORE2 check around setting of NET_IP_ALIGNAlexander Duyck2010-07-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the CONFIG_MCORE2 check from around NET_IP_ALIGN. It is based on a suggestion from Andi Kleen. The assumption is that there are not any x86 cores where unaligned access is really slow, and this change would allow for a performance improvement to still exist on configurations that are not necessarily optimized for Core 2.
