2017-08-31net: hns3: Fixes the wrong IS_ERR check on the returned phydev valueSalil Mehta1-1/+1
This patch removes the wrong check being done for the phy device being returned by the mdiobus_get_phy() function. This function never returns the error pointers.

2017-08-18net: hns3: Fixes the missing u64_stats_fetch_begin_irq in 64-bit stats fetchSalil1-0/+2
This patch fixes the missing u64_stats_fetch_begin_irq() while trying to atomically do 64-bit RX/TX fetch. We did not get any error during test as our SoC is 64-bit so all of these seq/lock operations results in NOOP. As such, this seq lock supports has been added for the sake of completion if this code ever runs on 32-bit platform and we are trying to do 64-bit stats fetch.

2017-08-17net: hns3: ensure media_type is unitializedColin Ian King1-1/+1
Media type is only set if h->ae_algo->ops->get_media_type is called so there is a possibility that media_type is uninitialized when it is used a switch statement. Fix this by initializing media_type to HNAE3_MEDIA_TYPE_UNKNOWN.

2017-08-07hns3: fix unused function warningArnd Bergmann1-15/+12
Without CONFIG_PCI_IOV, we get a harmless warning about an unused function: drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.c:2273:13: error: 'hclge_disable_sriov' defined but not used [-Werror=unused-function] The #ifdefs in this driver are obviously wrong, so this just removes them and uses an IS_ENABLED() check that does the same thing correctly in a more readable way.

2017-08-07net: sched: get rid of struct tc_to_netdevJiri Pirko1-2/+4
