      ====================
      net: systemport: Unmap queues upon DSA unregister event
      
      This patch series fixes the unbinding/binding of the bcm_sf2 switch
      driver along with bcmsysport which monitors the switch port queues.
      Because the driver was not processing the DSA_PORT_UNREGISTER event, we
      would not be unmapping switch port/queues, which could cause incorrect
      decisions to be made by the HW (e.g: queue always back-pressured).

      Florian Fainelli authored
      Binding and unbinding the switch driver which creates the DSA slave
      network devices for which we set-up inspection would lead to
      undesireable effects since we were not clearing the port/queue mapping
      to the SYSTEMPORT TX queue.

      net: systemport: Simplify queue mapping logic · 25c44070
      Florian Fainelli authored
      The use of a bitmap speeds up the finding of the first available queue
      to which we could start establishing the mapping for, but we still have
      to loop over all slave network devices to set them up. Simplify the
      logic to have a single loop, and use the fact that a correctly
      configured ring has inspect set to true. This will make things simpler
      to unwind during device unregistration.

      net: dsa: bcm_sf2: Turn on PHY to allow successful registration · c04a17d2
      Florian Fainelli authored
      We are binding to the PHY using the SF2 slave MDIO bus that we create,
      binding involves reading the PHY's MII_PHYSID1/2 which won't be possible
      if the PHY is turned off. Temporarily turn it on/off for the bus probing
      to succeeed. This fixes unbind/bind problems where the port connecting
      to that PHY would be in error since it could not connect to it.

      net: dsa: bcm_sf2: Store rules in lists
      
      This patch series changes the bcm-sf2 driver to keep a copy of the
      inserted rules as opposed to using the HW as a storage area for a number
      of reasons:
      
      - this helps us with doing duplicate rule detection in a faster way, it
        would have required a full rule read before
      
      - this helps with Pablo's on-going work to convert ethtool_rx_flow_spec
        to a more generic flow rule structure by having fewer code paths to
        convert to the new structure/helpers
      
      - we need to cache copies to restore them during drive resumption,
        because depending on the low power mode the system has entered, the
        switch may have lost all of its context

      Florian Fainelli authored
      Some of the system suspend states that we support wipe out entirely the
      HW contents. If we had a Wake-on-LAN filter programmed prior to going
      into suspend, but we did not actually wake-up from Wake-on-LAN and
      instead used a deeper suspend state, make sure we restore the CID number
      that we need to match against.

      net: dsa: bcm_sf2: Restore CFP rules during system resume · 1c0130f0
      Florian Fainelli authored
      The hardware can lose its context during system suspend, and depending
      on the switch generation (7445 vs. 7278), while the rules are still
      there, they will have their valid bit cleared (because that's the
      fastest way for the HW to reset things). Just make sure we re-apply them
      coming back from resume. The 7445 switch is an older version of the core
      that has some quirky RAM technology requiring a delete then re-inser to
      guarantee the RAM entries are properly latched.

      net: dsa: bcm_sf2: Keep copy of inserted rules · ae7a5aff
      Florian Fainelli authored
      We tried hard to use the hardware as a storage area, which made things
      needlessly complex in that we had to both marshall and unmarshall the
      ethtool_rx_flow_spec into what the CFP hardware understands but it did
      not require any driver level allocations, so that was nice.
      
      Keep a copy of the ethtool_rx_flow_spec rule we want to insert, and also
      make sure we don't have a duplicate rule already. This greatly speeds up
      the deletion time since we only need to clear the slice's valid bit and
      not perform a full read.
      
      This is a preparatory step for being able to restore rules upon system
      resumption where the hardware loses its context partially or entirely.

      ISDN: eicon: Remove driver · a8d62195
      Olof Johansson authored
      I started looking at the history of this driver, and last time the
      maintainer was active on the mailing list was when discussing how to
      remove it. This was in 2012:
      
      https://lore.kernel.org/lkml/4F4DE175.30002@melware.de/
      
      It looks to me like this has in practice been an orphan for quite a while.
      It's throwing warnings about stack size in a function that is in dire
      need of refactoring, and it's probably a case of "it's time to call it".

        attached to a function that belongs to a module that isn't loaded yet.
        When the kprobe trace event is added, the offset would be truncated
        after it was parsed, and when the module is loaded, it would use the
        symbol without the offset (as the nul character added by the parsing
        would not be replaced with the original character)"

      There is no reason to discard using source link local address when
      remote netconsole IPv6 address is set to be link local one.
      
      The patch allows administrators to use IPv6 netconsole without
      explicitly configuring source address:

      rtnetlink: restore handling of dumpit return value in rtnl_dump_all() · 5e1acb4a
      Alexey Kodanev authored
      For non-zero return from dumpit() we should break the loop
      in rtnl_dump_all() and return the result. Otherwise, e.g.,
      we could get the memory leak in inet6_dump_fib() [1]. The
      pointer to the allocated struct fib6_walker there (saved
      in cb->args) can be lost, reset on the next iteration.
      
      Fix it by partially restoring the previous behavior before
      commit c63586dc ("net: rtnl_dump_all needs to propagate
      error from dumpit function"). The returned error from
      dumpit() is still passed further.
