2018-02-27net: Convert cfg802154_pernet_opsKirill Tkhai1-0/+1
These pernet_operations have only exit method, which moves devices from cfg802154_rdev_list to init_net. This may occur in any time from nl802154_wpan_phy_netns(), so we are nice with rtnl_lock() synchronization.

2018-02-26i40e/i40evf: use SW variables for hang detectionAlan Brady3-7/+13
The i40e_detect_recover_hung function uses the i40e_get_tx_pending function to determine if there are packets stalled on the ring. i40e_get_tx_pending calculates the pending packets using the head writeback value and HW tail. If the queue is stopped and we lose the interrupt to update our next_to_clean then we a) won't get another interrupt to clean because queue is stopped b) we won't catch the problem with i40e_detect_recover_hung because the HW values look like there's no packets waiting to be transmitted. Using the SW values we can catch the issue because next_to_clean will be out of sync with head writeback. This has the added benefit being less CPU intensive because we don't need to reach into the hardware to get the values.

It appears that the single port Ether controllers having TSU (like SH7734/ R8A7740) need the same kind of treating in sh_eth_tsu_init() as R7S72100 currently has -- they also don't have the TSU registers related e.g. to passing the frames between ports. Add the 'sh_eth_cpu_data::dual_port' flag and use it as a new criterion for taking a "short path" in the TSU init sequence in order to avoid writing to the non-existent registers...

2018-02-26ixgbe: prevent ptp_rx_hang from running when in FILTER_ALL modeJacob Keller1-1/+2
On hardware which supports timestamping all packets, the timestamps are recorded in the packet buffer, and the driver no longer uses or reads the registers. This makes the logic for checking and clearing Rx timestamp hangs meaningless. If we run the ixgbe_ptp_rx_hang() function in this case, then the driver will continuously spam the log output with "Clearing Rx timestamp hang". These messages are spurious, and confusing to end users. The original code in commit a9763f3cb54c ("ixgbe: Update PTP to support X550EM_x devices", 2015-12-03) did have a flag PTP_RX_TIMESTAMP_IN_REGISTER which was intended to be used to avoid the Rx timestamp hang check, however it did not actually check the flag before calling the function. Do so now in order to stop the checks and prevent the spurious log messages.

If indir == 0 in the ixgbe_set_rxfh(), it is unnecessary to write the HW. Because redirection table is not changed. Signed-off-by: Tonghao Zhang <xiangxia.m.yue@gmail.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2018-02-26xen-netback: make function xenvif_rx_skb staticColin Ian King1-1/+1
The function xenvif_rx_skb is local to the source and does not need to be in global scope, so make it static. Cleans up sparse warning: drivers/net/xen-netback/rx.c:422:6: warning: symbol 'xenvif_rx_skb' was not declared. Should it be static?
