Move the USB element out of vnt_tx_packet and vnt_beacon_xmit to
vnt_tx_context with sk_buff passed in parameters with the data now
between skb->data and skb->len.

The vnt_tx_usb header is moved from vnt_tx_buffer to usbpipe.h with the

The CONTEXT enums types are aligned with usb ones and CONTEXT_MGMT_PACKET
is removed and is never be used.

The skb_push in vnt_tx_packet is now only ever used with
vnt_get_hdr_size with variables tx_bytes and tx_header_size removed.

staging: vt6656: Use sk_buff buffer for tx header

mac80211 can provide space for the driver to put a tx header on
the skb buffer instead coping the entire frame on to a local
buffer with the header.

To use this extra_tx_headroom must be set in mac80211 with the largest
possible header which is struct vnt_tx_buffer.

The driver has 8 possible combinations of tx header size which
are found in vnt_get_hdr_size replacing vnt_mac_hdr_pos.

staging: vt6656: Use const for read only data

Use const for the arrays that are used as "read only". Also, modify the
prototype of vnt_control_out_blocks() function to use a pointer to a
const type.

The vnt_vt3184_al2230 array can't be converted to const as it's modified
later.

Then in the vnt_vt3184_init() function use two types of pointers (to
const type and to no const type) to avoid the compiler warning:

assignment discards 'const' qualifiers from pointer target type

This way decrease the .data section and increase the .rodata section
limiting the surface attack.

The TBTT set at 500 wake-up sequence and always listen flagged on;
100 No TBTT
200 No TBTT
300 No TBTT
400 No TBTT
500 TBTT - beacon heard and passed through
600 No TBTT

A further enhancement because the TBTT is more precise
the dtim_period can be used instead.

When Power save is off the TBTT continues to run at the listen
interval but all the other beacons are passed.

The code in vnt_int_process_data is no longer required.

Now that the SPDX tag is in all vt6656 files, that identifies the

like the address (sometimes incorrect) for the FSF which is never
needed.
