Merge branch 'net-sched-gred-introduce-per-virtual-queue-attributes'

Jakub Kicinski says:

====================
net: sched: gred: introduce per-virtual queue attributes

This series updates the GRED Qdisc.  The Qdisc matches nfp offload very
well, but before we can offload it there are a number of improvements
to make.

First few patches add extack messages to the Qdisc and pass extack
to netlink validation.

Next a new netlink attribute group is added, to allow GRED to be
extended more easily.  Currently GRED passes C structures as attributes,
and even an array of C structs for virtual queue configuration.  User
space has hard coded the expected length of that array, so adding new
fields is not possible.

New two-level attribute group is added:

  [TCA_GRED_VQ_LIST]
    [TCA_GRED_VQ_ENTRY]
      [TCA_GRED_VQ_DP]
      [TCA_GRED_VQ_FLAGS]
      [TCA_GRED_VQ_STAT_*]
    [TCA_GRED_VQ_ENTRY]
      [TCA_GRED_VQ_DP]
      [TCA_GRED_VQ_FLAGS]
      [TCA_GRED_VQ_STAT_*]
    [TCA_GRED_VQ_ENTRY]
       ...

Statistics are dump only. Patch 4 switches the byte counts to be 64 bit,
and patch 5 introduces the new stats attributes for dump.  Patch 6
switches RED flags to be per-virtual queue, and patch 7 allows them
to be dumped and set at virtual queue granularity.
