It's way past it's usefulness. And this gets rid of a bunch of stray ->rt_{dst,src} references. Even the comment documenting the macro was inaccurate (stated default was 1 when it's 0).

2011-05-16sfc: Use netif_device_{detach,attach}() around reset and self-testBen Hutchings
We need to keep the TX queues stopped throughout a reset, without triggering the TX watchdog and regardless of the link state. The proper way to do this is to use netif_device_{detach,attach}() just as we do around suspend/resume, rather than the current bodge of faking link-down. Since we also need to do this during an offline self-test and we perform a reset during that, add these function calls outside of efx_reset_down() and efx_reset_up().

2011-05-16net: Change netdev_fix_features messages loglevelMichał Mirosław

Illegal checksum combinations can only be caused by driver bug, so promote those messages to WARN. Since GSO without SG will now only cause DEBUG message from netdev_fix_features(), remove the workaround from register_netdevice().

2011-05-16vmxnet3: Fix inconsistent LRO state after initializationThomas Jarosch
During initialization of vmxnet3, the state of LRO gets out of sync with netdev->features. This leads to very poor TCP performance in a IP forwarding setup and is hitting many VMware users. Simplified call sequence: 1. vmxnet3_declare_features() initializes "adapter->lro" to true. 2. The kernel automatically disables LRO if IP forwarding is enabled, so vmxnet3_set_flags() gets called. This also updates netdev->features. 3. Now vmxnet3_setup_driver_shared() is called. "adapter->lro" is still set to true and LRO gets enabled again, even though netdev->features shows it's disabled. Fix it by updating "adapter->lro", too. The private vmxnet3 adapter flags are scheduled for removal in net-next, see commit a0d2730c9571aeba793cb5d3009094ee1d8fda35 "net: vmxnet3: convert to hw_features".

Commit 747df2258b1b9a2e25929ef496262c339c380009 ('sfc: Always map MCDI shared memory as uncacheable') introduced a separate mapping for the MCDI shared memory (MC_TREG_SMEM).

This adds sparse RCU annotations to most of mac80211, only the mesh code remains to be done. Due the the previous patches, the annotations are pretty simple. The only thing that this actually changes is removing the RCU usage of key->sta in debugfs since this pointer isn't actually an RCU-managed pointer (it only has a single assignment done before the key even goes live).
