2014-03-29T22:48:54+00:00

Conflicts: drivers/net/ethernet/marvell/mvneta.c The mvneta.c conflict is a case of overlapping changes, a conversion to devm_ioremap_resource() vs. a conversion to netdev_alloc_pcpu_stats. Signed-off-by: David S. Miller

ifb: Remove vlan acceleration from vlan_features

2014-03-28T21:16:50+00:00

Do not include vlan acceleration features in vlan_features as that precludes correct Q-in-Q operation. Signed-off-by: Vlad Yasevich Signed-off-by: David S. Miller

net: Replace u64_stats_fetch_begin_bh to u64_stats_fetch_begin_irq

2014-03-15T02:41:36+00:00

Replace the bh safe variant with the hard irq safe variant. We need a hard irq safe variant to deal with netpoll transmitting packets from hard irq context, and we need it in most if not all of the places using the bh safe variant. Except on 32bit uni-processor the code is exactly the same so don't bother with a bh variant, just have a hard irq safe variant that everyone can use. Signed-off-by: "Eric W.

net: Explicitly initialize u64_stats_sync structures for lockdep

2013-11-06T11:40:25+00:00

In order to enable lockdep on seqcount/seqlock structures, we must explicitly initialize any locks. The u64_stats_sync structure, uses a seqcount, and thus we need to introduce a u64_stats_init() function and use it to initialize the structure. This unfortunately adds a lot of fairly trivial initialization code to a number of drivers. But the benefit of ensuring correctness makes this worth while. Because these changes are required for lockdep to be enabled, and the changes are quite trivial, I've not yet split this patch out into 30-some separate patches, as I figured it would be better to get the various maintainers thoughts on how to best merge this change along with the seqcount lockdep enablement. Feedback would be appreciated! Signed-off-by: John Stultz Acked-by: Julian Anastasov Signed-off-by: Peter Zijlstra Cc: Alexey Kuznetsov Cc: "David S.

ifb: fix oops when loading the ifb failed

If __rtnl_link_register() return faild when loading the ifb, it will take the wrong path and get oops, so fix it just like dummy. Signed-off-by: Ding Tianhong Signed-off-by: David S. Miller

ifb: fix rcu_sched self-detected stalls

2013-07-11T01:44:03+00:00

According to the commit 16b0dc29c1af9df341428f4c49ada4f626258082 (dummy: fix rcu_sched self-detected stalls) Eric Dumazet fix the problem in dummy, but the ifb will occur the same problem like the dummy modules. Trying to "modprobe ifb numifbs=30000" triggers : INFO: rcu_sched self-detected stall on CPU After this splat, RTNL is locked and reboot is needed. We must call cond_resched() to avoid this, even holding RTNL. Signed-off-by: Ding Tianhong Signed-off-by: David S. Miller

net: vlan: rename NETIF_F_HW_VLAN_* feature flags to NETIF_F_HW_VLAN_CTAG_*

2013-04-19T18:45:26+00:00

Rename the hardware VLAN acceleration features to include "CTAG" to indicate that they only support CTAGs. Follow up patches will introduce 802.1ad server provider tagging (STAGs) and require the distinction for hardware not supporting acclerating both.
