Merge branch 'net-prepare-for-removal-of-net-dev_index_head'
Eric Dumazet says:
====================
net: prepare for removal of net->dev_index_head
This series changes rtnl_fdb_dump, last iterator using net->dev_index_head[]
First patch creates ndo_fdb_dump_context structure, to no longer
assume specific layout for the arguments.
Second patch adopts for_each_netdev_dump() in rtnl_fdb_dump(),
while changing two first fields of ndo_fdb_dump_context.
Third patch removes the padding, thus changing the location
of ctx->fdb_idx now that all users agree on how to retrive it.
After this series, the only users of net->dev_index_head
are __dev_get_by_index() and dev_get_by_index_rcu().
We have to evaluate if switching them to dev_by_index xarray
would be sensible.
