This feature patchset includes the following changes:
- Cleanup work by Markus Pargmann and Sven Eckelmann (six patches) - Initial Netlink support by Matthias Schiffer (two patches) - Throughput Meter implementation by Antonio Quartulli, a kernel-space traffic generator to estimate link speeds. This feature is useful on low-end WiFi APs where running iperf or netperf from userspace gives wrong results due to heavy userspace/kernelspace overhead. (two patches) - API clean-up work by Antonio Quartulli (one patch) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABCgAGBQJXel3cAAoJEKEr45hCkp6hxs0P/jQZBJ37Bd4EHRGdhvCJWwsO j79zr7mIECub8a6PMkO1GI87ksJNtRdRw7XAIbLKTwsKEsUE0Gpv/MLLKgv/nD7X zatcoI4DujkgSojZIcOV/061+M9FAnCtAYv13jIS8nbXdqfGPxPfLua6Zbvx1GS2 z/Rqg/WbB2qDtDlUrp0W/8oXQ+k6062G7GigroPLmjdWd5lF0H6ly4loWsxFyr0U GVl44HM4nOj7DwkVlrGoOXnAbjpz9TNC/aA5TIS/tLFZkm5dvJjjKLDbxo5NM9aq hRhFy8Gbe0TmOxV3mKZUT1oHuaHgFDY2tADLiLF2g/ijgaTetXCBJ6DXQ7BkiZnh +t1fnutOB1D05+cZGDmlfb2bFXO6vdDwNzKYuPdeW0tUOVwzNIaMK+US1HffUD3F ciK/cALsLbfJ3QkUHJclE57baMuB2c7YWJUxGdp2r4lKHak6tc8+BsornI6lB6qY kcxip6EEaT7edjT66Qjq8GtFK7WIri5nHI9n5Js+Wwl1QENvkLmZRQ6qZexwSplS RTZmmO+i+Y4rGDa3xoVSlC+CEUO7D4VwhET2Jir7KJrVS+pFNRAmfpUNWxeauAls D1xWgBrWjjOYu5i3LjwC6cHl4eTWxBwWmBUaxLUUeyoR22ulIs6bXCQMWOLMbupd q8k2B5BW9waTAgb4Tam9 =PFHu -----END PGP SIGNATURE----- Merge tag 'batadv-next-for-davem-20160704' of git://git.open-mesh.org/linux-merge Simon Wunderlich says: ==================== This feature patchset includes the following changes: - Cleanup work by Markus Pargmann and Sven Eckelmann (six patches) - Initial Netlink support by Matthias Schiffer (two patches) - Throughput Meter implementation by Antonio Quartulli, a kernel-space traffic generator to estimate link speeds.
