Comparing the existing TX_BITRATE parsing code (in
mwifiex_parse_htinfo()) with the RX bitrate histograms in debugfs.c, it
appears that the rxpd_rate and rxpd_htinfo fields have the same format.
At least, they give reasonable results when I parse them this way.

So this patch adds support for RX_BITRATE to our station info dump.

Along the way, I add legacy bitrate parsing into the same function,
using the debugfs code (mwifiex_histogram_read() and
mwifiex_adjust_data_rate()) as reference.

Additionally, to satisfy the requirements of
NL80211_STA_INFO_RX_BITRATE, I skip logging the bitrate of multicast
packets. This shouldn't add a lot of overhead to the RX path, as there
are already several similar 802.3 header checks in this same codepath.
We can also bias the branch behavior to favor unicast, as that's the
common performance-sensitive case.

I'd consider this support somewhat experimental, as I have zero
documentation from Marvell. But the existing driver code gives me good
reason to think this is correct.

I've tested this on a few different 802.11{a,b,g,n,ac} networks, and the
reported bitrates look good to me.

This patchset is a continuation to earlier submitted four patch

4. octeontx2-af: NPC MCAM support and FLR handling

This patch series adds support for below

NPC block:
- Add NPC(mkex) profile support for various Key extraction configurations

NIX block:
- Enable dynamic RSS flow key algorithm configuration
- Enhancements on Rx checksum and error checks
- Add support for Tx packet marking support
- TL1 schedule queue allocation enhancements
- Add LSO format configuration mbox
- VLAN TPID configuration
- Skip multicast entry init for broadcast tables

v2:

- Rename FLOW_* to NIX_FLOW_* to avoid serious global namespace collisions,
as we have various FLOW_* definitions coming from
include/uapi/linux/pkt_cls.h for example.(David Miller)
- Pack the arguments of rvu_get_tl1_schqs() function

The following set of NPC registers allow the driver to configure NPC
to generate different key value schemes to compare against packet
payload in MCAM search.

NPC_AF_INTF(0..1)_KEX_CFG
NPC_AF_KEX_LDATA(0..1)_FLAGS_CFG
NPC_AF_INTF(0..1)_LID(0..7)_LT(0..15)_LD(0..1)_CFG
NPC_AF_INTF(0..1)_LDATA(0..1)_FLAGS(0..15)_CFG

Currently, the AF driver populates these registers to
configure the default values to address the most common
use cases such as key generation for channel number + DMAC.

The secure firmware stores different configuration
value of these registers to enable different NPC use case
along with the name for the lookup.

Patch loads profile binary from secure firmware over
the exiting CGX mailbox interface and apply the profile.

AF driver shall fall back to the default configuration
in case of any errors.

The AF consumer driver can know the selected profile
on response to NPC_GET_KEX_CFG mailbox by introducing
mkex_pfl_name in the struct npc_get_kex_cfg_rsp.

- Limit TL1 allocation to 2 per lmac.
  One could be for the normal link and one for IEEE802.3br

  Effectively all the VF's of an RVU PF(lmac) share the two TL1 schqs.
- TL1 cannot be freed once allocated.
- Allow VF's to only apply default config to TL1 if not

With MSG_ZEROCOPY, each skb holds a reference to a struct ubuf_info.
Release of its last reference triggers a completion notification.

The TCP stack in tcp_sendmsg_locked holds an extra ref independent of
the skbs, because it can build, send and free skbs within its loop,
possibly reaching refcount zero and freeing the ubuf_info too soon.

The UDP stack currently also takes this extra ref, but does not need
it as all skbs are sent after return from __ip(6)_append_data.

Avoid the extra refcount_inc and refcount_dec_and_test, and generally
the sock_zerocopy_put in the common path, by passing the initial
reference to the first skb.

This approach is taken instead of initializing the refcount to 0, as
that would generate error "refcount_t: increment on 0" on the
next skb_zcopy_set.
