2017-08-23net: mvpp2: software tso supportAntoine Ténart1-14/+157
The patch uses the tso API to implement the tso functionality in Marvell PPv2 driver. Using iperf and 10G ports, using TSO shows a significant performance improvement by a factor 2 to reach around 9.5Gbps in TX; as well as a significant CPU usage drop (from 25% to 15%).

2017-08-23liquidio: change manner of detecting whether or not NIC firmware is loadedFelix Manlunas3-9/+15
In the NIC firmware, the 1-bit flag indicating "firmware is loaded" moved from SLI_SCRATCH_1 to SLI_SCRATCH_2 (these are Octeon general-purpose scratch registers). Make the PF driver conform to this change. Remove code that sets the "firmware is loaded" flag because it's now the firmware's job to do that. In the code that detects whether or not the firmware is loaded, don't just rely on checking the "firmware is loaded" flag because that may cause a rare false negative. Add code that deduces whether or not the firmware is loaded; that will never give a false negative. Also bump up driver version to match newer NIC firmware.

2017-08-22net: mvpp2: initialize the XLG MAC when using a portAntoine Ténart1-0/+25
This adds a routine to initialize the XLG MAC at the port level when using a port and the XAUI/10GKR interface mode. This wasn't done until this commit, and the mvpp2 driver was relying on the bootloader/firmware initialization. This doesn't mean everything is configured in the mvpp2 driver now, but it helps reducing the gap.

2017-08-22hv_netvsc: Add ethtool handler to set and get UDP hash levelsHaiyang Zhang2-8/+72
The patch add the functions to switch UDP hash level between L3 and L4 by ethtool command. UDP over IPv4 and v6 can be set differently. The default hash level is L4. We currently only allow switching TX hash level from within the guests. On Azure, fragmented UDP packets have high loss rate with L4 hashing. Using L3 hashing is recommended in this case. For example, for UDP over IPv4 on eth0: To include UDP port numbers in hasing: ethtool -N eth0 rx-flow-hash udp4 sdfn To exclude UDP port numbers in hasing: ethtool -N eth0 rx-flow-hash udp4 sd To show UDP hash level: ethtool -n eth0 rx-flow-hash udp4 Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: David S.
