The TVQM tells us the initial write pointer for a queue,
but that write pointer is in WiFi sequence number unit
and not in TFD index unit. Which means that the write
pointer in the TVQM's response can be bigger than the
Tx queue ring size.

Fix that by modulo'ing the write pointer from the TVQM
with the Tx queue size.

99976fc084 brcmfmac: fix wrong num_different_channels when mchan feature enabled
When the device/firmware supports multi-channel, it can have P2P
connection and regular connection with AP simultaneous. In this case,
the num_different_channels in wiphy info was not correct when firmware
supports multi-channel (The iw wiphy# info showed "#channels <= 1" in
interface combinations). It caused association failed and error message
"CTRL-EVENT-FREQ-CONFLICT error" in wpa_supplicant when P2P GO interface
was running at the same time.
The root cause is that the num_different_channels was always overridden
to 1 in brcmf_setup_ifmodes even multi-channel was enabled.
We correct the logic by moving num_different_channels setting forward.

53b9483565 net: vrf: Add extack messages for newlink failures
Add extack error messages for failure paths creating vrf devices. Once
extack support is added to iproute2, we go from the unhelpful:
    $  ip li add foobar type vrf
    RTNETLINK answers: Invalid argument

to:
    $ ip li add foobar type vrf
    Error: VRF table id is missing
