2013-08-16qlcnic: Fix set driver version commandHimanshu Madhani2-3/+6
Driver was issuing set driver version command through all functions in the adapter. Fix the driver to issue set driver version once per adapter, through function 0.

2013-08-16net: tg3: fix NULL pointer dereference in tg3_io_error_detected and ↵Daniel Borkmann1-5/+8
tg3_io_slot_reset Commit d8af4dfd8 ("net/tg3: Fix kernel crash") introduced a possible NULL pointer dereference in tg3 driver when !netdev || !netif_running(netdev) condition is met and netdev is NULL. Then, the jump to the 'done' label calls dev_close() with a netdevice that is NULL. Therefore, only call dev_close() when we have a netdevice, but one that is not running.

2013-08-15drivers/net/ethernet/via/via-velocity.c: update napi implementationJulia Lawall1-1/+3
Drivers supporting NAPI should use a NAPI-specific function for receiving packets. Hence netif_rx is changed to netif_receive_skb. Furthermore netif_napi_del should be used in the probe and remove function to clean up the NAPI resource information.

2013-08-15Revert "cxgb3: Check and handle the dma mapping errors"Alexey Kardashevskiy1-83/+24
This reverts commit f83331bab149e29fa2c49cf102c0cd8c3f1ce9f9. As the tests PPC64 (powernv platform) show, IOMMU pages are leaking when transferring big amount of small packets (<=64 bytes), "ping -f" and waiting for 15 seconds is the simplest way to confirm the bug.

2013-08-14ethernet/arc/arc_emac - fix NAPI "work > weight" warningAlexey Brodkin1-1/+1
Initially I improperly set a boundary for maximum number of input packets to process on NAPI poll ("work") so it might be more than expected amount ("weight"). This was really harmless but seeing WARN_ON_ONCE on every device boot is not nice. So trivial fix ("<" instead of "<=") is here.

2013-08-09vxlan: fix a soft lockup in vxlan module removalCong Wang1-2/+0
This is a regression introduced by: commit fe5c3561e6f0ac7c9546209f01351113c1b77ec8 Author: stephen hemminger <stephen@networkplumber.org> Date: Sat Jul 13 10:18:18 2013 -0700 vxlan: add necessary locking on device removal The problem is that vxlan_dellink(), which is called with RTNL lock held, tries to flush the workqueue synchronously, but apparently igmp_join and igmp_leave work need to hold RTNL lock too, therefore we have a soft lockup! As suggested by Stephen, probably the flush_workqueue can just be removed and let the normal refcounting work. The workqueue has a reference to device and socket, therefore the cleanups should work correctly.

2013-08-02iwl4965: reset firmware after rfkill offStanislaw Gruszka2-5/+6
Using rfkill switch can make firmware unstable, what cause various Microcode errors and kernel warnings. Reseting firmware just after rfkill off (radio on) helped with that.

macvlan passthrough mode is special: it's not possible to switch to or from it through a netlink command. But if you try, the command will succeed, which is confusing.

2013-08-02net/mlx4_core: VFs must ignore the enable_64b_cqe_eqe module paramJack Morgenstein1-1/+1
Slaves get the 64B CQE/EQE state from QUERY_HCA, not from the module parameter. If the parameter is set to zero, the slave outputs an incorrect/irrelevant warning message that 64B CQEs/EQEs are supported but not enabled (even if the hypervisor has enabled 64B CQEs/EQEs).

2013-08-02net/mlx4_core: Don't give VFs MAC addresses which are derived from the PF MACOr Gerlitz1-10/+1
If the user has not assigned a MAC address to a VM, then don't give it MAC which is based on the PF one. The current derivation scheme is wrong and leads to VM MAC collisions when the number of cards/hypervisors becomes big enough. Instead, just give it zeros and let them figure out what to do with that. Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-08-018139cp: Add dma_mapping_error checkingNeil Horman1-3/+45
Self explanitory dma_mapping_error addition to the 8139 driver, based on this: https://bugzilla.redhat.com/show_bug.cgi?id=947250 It showed several backtraces arising for dma_map_* usage without checking the return code on the mapping. Add the check and abort the rx/tx operation if its failed. Untested as I have no hardware and the reporter has wandered off, but seems pretty straightforward.
