2014-03-28net: nlmon: flag nlmon devs with LLTX/SGDaniel Borkmann
As in xmit path we merely update statistics and free the skb, we can mark the device with LLTX feature, so that upper layers can avoid taking the single txq lock on xmit. While at it, also add missing NETIF_F_SG. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-03-28sh_eth: ensure pm_runtime cannot suspend the device during initBen Dooks
The pm_rumtime work queue is causing the device to be suspended during initialisation, thus the initialisation may not be able to access registers properly. As the code is called from a work queue, it is possible that this is not seen from certain configurations/builds due to the asynchronos nature of the code. Another issue has also been found where the network device registration calls back into the driver thus causing further pm_runtime calls that also caused issues with the MDIO bus code. This has now been checked and is the only place the MDIO can be called without the device open. Use pm_runtime_get_sync() and pm_runtime_put() to ensure that the pm system does not suspend it during the probe() call and remove the now unnecessary pm_runtime_resume() call. Also add a call in the error path to call pm_runtime_disable(). This fixes the external abort that can cause /sbin/init or other such init processed to die.

The node discovery domain is assigned when a bearer is enabled.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to e1000e, igb, i40e and i40evf Anjali provides i40e fix to remove the ATR filter on RST as well as FIN packets. Cleans up add_del_fdir() because it was used and implemented only for the add, so change the name and drop a parameter. Adds the ability to drop a flow if we wanted to and adds a flow director message level to be used for flow director specific messages. Mitch fixes an issue on i40evf where the Tx watchdog handler was causing an oops when sending an admin queue message to request a reset because the admin queue functions use spinlocks. Greg provides a change to i40e to make the alloc and free queue vector calls orthogonal. Shannon fixes i40e to verify the eeprom checksum and firmware CRC status bits, and shutdown the driver if they fail. This change stops the processing of traffic, but does not kill the PF netdev so that the NVMUpdate process still has a chance at fixing the image. Also provides a fix to make sure the VSI has a netdev before trying to use it in the debugfs netdev_ops commands. Jakub Kicinski provides patches for e1000e and igb to fix a number issues found in the PTP code. v2: - drop patch 11 "i40e: Add a fallback debug flow for the driver" from the series based on feedback from David Miller ==================== Signed-off-by: David S.

When the UniMAC block is configured to forward the CRC as part of the Ethernet frame (priv->crc_fwd_en, set by default), enabling the hardware RX checksum block unveiled that the dma_rxchk_bit was never set in the per-packet status bits (dma_flag in bcmgenet_desc_rx). This would make the chksum_ok variable to be never set to 1, and the networking stack would have to compute the packet checksums, which takes a substantial amount of time. In order for the RXCHK block to properly compute the packet checksum in hardware, we also need to set the RBUF_SKIP_FCS bit accordingly.
