Subject: [PATCH net-next v3 0/1] Add hw offload of TC police on MSCC ocelot

This patch series enables hardware offload of ingress port policing
on the MSCC ocelot board.

Changes v2 -> v3:

v3 now incorporates the following changes suggested by Jakub Kicinski:

 - Add a check in ndo_set_features() in order to prevent users to clear the
   NETIF_F_HW_TC flag while offload is active.

 - Reject the offload if the block is shared.

Changes v1 -> v2:

v2 now consists of only one patch: "[PATCH net-next v2 1/1] net: mscc:
ocelot: Implement port policers via tc command".

The patch, "[PATCH net-next 00/13] net: act_police offload support", from
Jakub Kicinski, removed the need for this patch:
"[PATCH net-next 1/3] net/sched: act_police: move police parameters".

Alexandre Belloni asked me to remove patch,
"[PATCH net-next 3/3] MIPS: generic: Add police related options to
ocelot_defconfig", from the series and instead send it through the MIPS
tree and I will do that.

The remaining patch is now the only patch in this series and all suggested
changes have been incorporated.
