2015-10-19i40e: Move error message to debug levelCatherine Sullivan1-3/+3
There is an error coming back from get_phy_capabilities that does not seem to have any functional implications. We will continue looking into why this error message is occurring, but in the meantime, we will move it to debug to avoid confusion.

2015-10-19i40e: fix for PHY NVM interaction problemCarolyn Wyborny1-6/+8
This patch fixes a problem where the NVMUpdate Tool, when using the PHY NVM feature, gets bad data from the PHY because of contention on the MDIO interface from get PHY capability calls from the driver during regular operations. The problem is fixed by adding a check if media is available before calling get PHY capability function because that bit is not set when device is in PHY interaction mode.

2015-10-19i40e/i40evf: adjust interrupt throttle less frequentlyJesse Brandeburg8-8/+53
The adaptive ITR (interrupt throttle rate) algorithm was adjusting the hardware's interrupt rate too frequently. This caused a lot of variation in the interrupt rate for fairly constant workloads.

2015-10-19i40e/i40evf: change dynamic interrupt thresholdsJesse Brandeburg4-12/+48
The dynamic algorithm, while now working, doesn't have good performance in 40G mode. One part of this patch addresses the high CPU utilization of some small streaming workloads that the driver should reduce CPU in. It also changes the minimum ITR that the dynamic algorithm will settle on, causing our minimum latency to go from 12us to about 14us, when using adaptive mode. It also changes the BULK interrupt rate to allow maximum throughput on a 40Gb connection with a single thread of transmit, clamping interrupt rate to 8000 for TX makes single thread traffic go too slow. The new ULTRA bulk setting is introduced and is used when the Rx packet rate on this queue exceeds 40000 packets per second. This value of 40000 was chosen because the automatic tuning of minimum ITR=20us means that a single queue can't quite achieve that many packets per second from a round-robin test.

Commit db6526dcb51b ("RDS: use rds_send_xmit() state instead of RDS_LL_SEND_FULL") which was trying to opportunistically finish the send request in same thread context. But because of above recursive lock hang with RDS TCP, the send work from rds_send_pong() needs to deferred to worker to avoid lock up. Given RDS ping is more of connectivity test than performance critical path, its should be ok even for transport like IB.

2015-10-18ipconfig: send Client-identifier in DHCP requestsLi RongQing2-1/+34
A dhcp server may provide parameters to a client from a pool of IP addresses and using a shared rootfs, or provide a specific set of parameters for a specific client, usually using the MAC address to identify each client individually. The dhcp protocol also specifies a client-id field which can be used to determine the correct parameters to supply when no MAC address is available. There is currently no way to tell the kernel to supply a specific client-id, only the userspace dhcp clients support this feature, but this can not be used when the network is needed before userspace is available such as when the root filesystem is on NFS. This patch is to be able to do something like "ip=dhcp,client_id_type, client_id_value", as a kernel parameter to enable the kernel to identify itself to the server.

2015-10-16netfilter: turn NF_HOOK into an inline functionArnd Bergmann2-4/+17
A recent change to the dst_output handling caused a new warning when the call to NF_HOOK() is the only used of a local variable passed as 'dev', and CONFIG_NETFILTER is disabled: net/ipv6/ip6_output.c: In function 'ip6_output': net/ipv6/ip6_output.c:135:21: warning: unused variable 'dev' [-Wunused-variable] The reason for this is that the NF_HOOK macro in this case does not reference the variable at all, and the call to dev_net(dev) got removed from the ip6_output function. To avoid that warning now and in the future, this changes the macro into an equivalent inline function, which tells the compiler that the variable is passed correctly but still unused. The dn_forward function apparently had the same problem in the past and added a local workaround that no longer works with the inline function. In order to avoid a regression, we have to also remove the #ifdef from decnet in the same patch.

2015-10-16mlxsw: cmd: Introduce FID-offset flooding tablesIdo Schimmel3-0/+18
Packets destined to offloaded netdevs will be classified to FIDs in the device and flooded in case of BUM. The flooding table used is of type FID-offset, which allows one to create different flooding domains for different FIDs and specify the offset in the flooding table for each FID (not necessarily equal to FID or VID). Add support for this flooding table type, by exposing the configuration of the number of tables from this type and their size.

2015-10-16mlxsw: cmd: Introduce per-FID flooding tablesIdo Schimmel3-0/+19
In the newly introduced Spectrum switch ASIC, packets destined to not offloaded netdevs will be classified to special FIDs (vFIDs) in the device and flooded to the CPU port. The flooding table used is of type per-FID, which allows one to create different flooding domains for different vFIDs. While using a simple single-entry flood table is certainly sufficient at this point, we do plan to offload 802.1D bridges involving VLAN interfaces, thus making this change necessary. Add support for this flooding table type, by exposing the configuration of the number of tables from this type and their size.
