====================
Not much for -next so far, but here it goes:
 * send more nl80211 events for interfaces
 * remove useless network/transport offset mangling code
 * validate beacon intervals identically for all interface types
 * use driver rate estimates for mesh
 * fix a compiler type/signedness warning

net: don't print error when allocating urb fails

This per-subsystem series is part of a tree wide cleanup. usb_alloc_urb() uses
kmalloc which already prints enough information on failure. So, let's simply
remove those "allocation failed" messages from drivers like we did already for
other -ENOMEM cases. gkh acked this approach when we talked about it at LCJ in
Tokyo a few weeks ago.

net: thunderx: Support for newer chips and miscellaneous patches

This patch series adds support for VNIC on 81xx and 83xx SOCs.
81xx/83xx is different from 88xx in terms of capabilities and new type
of interfaces supported (eg: QSGMII, RGMII) and have DLMs instead of
QLMs which allows single BGX to have interfaces of different LMAC types.

Also included some patches which are common for all 88xx/81xx/83xx
SOCs like using netdev's name while registering irqs, reset receive
queue stats and some changes to use standard API for split buffer Rx
packets, generating RSS key e.t.c

PS: Most of the patches were submitted earlier under different series but
for some reason were not picked up by patchwork. Since new patches have been
added in the meantime, resubmitting all as a new patchset.

Changes from v1:
- Incorporated Yuval Mintz's suggestion to use generic API to set minimum
  queue count i.e by using netif_get_num_default_rss_queues().
- Resolved a compilation issue reported by test robot while compiling
  patch 'Add support for 16 LMACs of 83xx'

Setting BGXX_SPUX_MISC_CONTROL::RX_PACKET_DIS is not needed as
packet reception is anyway disabled by BGXX_CMRX_CONFIG::DATA_PKT_RX_EN.
Also setting RX_PACKET_DIS causes a bogus remote fault condition
which delays link detection.

When SQ/TXQ is reclaimed i.e reset it's stats also automatically reset
by HW. This is not the case with RQ. Also VF doesn't have write access
to statistics counter registers. Hence a new Mbox msg is introduced which
supports resetting RQ, SQ and full Qset stats. Currently only RQ stats
are being reset using this mbox message.

On 88xx all LMACs in a BGX will be in same mode but on 81xx

These changes move lmac_type, lane2serdes fields into per lmac
struct from BGX struct. Got rid of qlm_mode field which has become
redundant with these changes. And now no of valid LMACs is read
from CSRs configured by low level firmware and figuring out the
