2010-07-11cxgb4: exclude registers with read side effects from register dumpsDimitris Michailidis1-10/+13
A few registers have side effects on reads, eg FIFO pointers that auto advance or mailboxes which change ownership when read. They are unsafe to read so exclude them from ethtool register dumps. Bump ethtool_regs.version to indicate the changed register set. Signed-off-by: Dimitris Michailidis <dm@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This patch reverts commit 52cdf8526fe24f11d300b75458ddee017f3f4c88, entitled "tg3: Prevent a PCIe tx glitch".

2010-07-09net: Get rid of rtnl_link_stats64 / net_device_stats unionBen Hutchings4-49/+56
In commit be1f3c2c027cc5ad735df6a45a542ed1db7ec48b "net: Enable 64-bit net device statistics on 32-bit architectures" I redefined struct net_device_stats so that it could be used in a union with struct rtnl_link_stats64, avoiding the need for explicit copying or conversion between the two. However, this is unsafe because there is no locking required and no lock consistently held around calls to dev_get_stats() and use of the statistics structure it returns. In commit 28172739f0a276eb8d6ca917b3974c2edb036da3 "net: fix 64 bit counters on 32 bit arches" Eric Dumazet dealt with that problem by requiring callers of dev_get_stats() to provide storage for the result. This means that the net_device::stats64 field and the padding in struct net_device_stats are now redundant, so remove them. Update the comment on net_device_ops::ndo_get_stats64 to reflect its new usage. Change dev_txq_stats_fold() to use struct rtnl_link_stats64, since that is what all its callers are really using and it is no longer going to be compatible with struct net_device_stats. Eric Dumazet suggested the separate function for the structure conversion.
