[PATCH net-next] macb: Add hardware PTP support.

This patch is based on original Harini's patch and Andrei's patch, implemented in aseparate file to ease the review/maintanance and integration with other platforms. In case that macb is compiled as a module, it has been renamed to cadence-macb.ko to avoid naming confusion in Makefile. This

[PATCH] net: ipv4: fix multipath RTM_GETROUTE behavior when iif is given

inet_rtm_getroute synthesizes a skeletal ICMP skb, which is passed to ip_route_input when iif is given. If a multipath route is present for the designated destination, ip_multipath_icmp_hash ends up being called, which uses the source/destination addresses within the skb to calculate a hash.

xilinx_axienet: No interrupts asserted in Tx path?

Hi I'm trying to use tri_mode_ethernet_mac & axi_dma cores from Vivado 2016.2, but I'm facing several problems that I believe are related to the linux' driver for these modules, xilinx_axienet_main.c First of all, I've noticed that __axienet_device_reset is called twice (once for TX and once
