* __le16 scan_type;
* __le16 capability;
* struct rate_set16_t rate_set;

Factor out these members into a common substructure of type
'hostif_request_t'.  This allows a large portion of the request
initialization code in ks_hostif.c to be factored out into the
'init_request' function.

`external_ai_queue_in_use()` is supposed to return 1 if the external
channel sequencer is in use by an AI command, else return 0.  If the
"read" subdevice (which is the AI subdevice) is not busy then no AI
command is running so the external channel sequencer is not in use, so
the function should return 0.  Unfortunately, the function's "read"
subdevice busy test is inverted, so the function always returns 0 when
the "read" subdevice is busy.  Worse, if the "read" subdevice is
not busy the subsequent call to `use_internal_queue_6xxx()` results in a
null pointer dereference if a previous AI command used a channel list
with a length greater than 1.

This reverts commit f5f3a2c6 ("staging: comedi: cb_pcidas64: change
params to external_ai_queue_in_use()").  The
`external_ai_queue_in_use()` was being called from `ao_cmd()` with
pointers to the "write" subdevice and AO command, but is supposed to
check whether the external AI queue is currently in use by the "read"
subdevice and AI command.  In fact, the return value always indicated
that the external AI queue was not in use in this case (because the AO
command's channel list is sequential), so was fairly useless.  (However,
even before the reverted commit, the logic in
`external_ai_queue_in_use()` was wrong.  That will be corrected in a
subsequent commit.)

Use the lnet_magic_accept() function to compare 'magic' against
LNET_PROTO_TCP_MAGIC for the appropriate string for an error message.

The original fix removed an unneeded byte-ordering cast because the define
was already CPU byte-ordered and it was assumed that 'magic' was CPU
byte-ordered, too.

Now modify the if-statement to use the appropriate lnet_accept_magic()
function in order to be consistent with similar tests. This will allow
the code to be consistent with the general understanding that 'magic'
should be in host-byte-order for the peer that sent the message.

Add support for SoCs from the mt7621 family. These all have 2 GMAC ports,
both of which are attached to the same internal 1000MBit switch. Currently
we only support GMAC1 as the sole CPU port. MT7621 is very similar to
MT7620 with only a few registers having different offsets. MT7621 is the
first SoC to have the new QDMA engine builtin. The older PDMA engine is
also present. unfortunatley, to get the best performance we need to run RX
on PDMA and TX on QDMA. This SoC is also the first to have TX vlan
offloading and TSO6 support.

NeilBrown: the driver didn't work when I tested, so I changed it
  to match known-working code as much as possible.  This included
  converting to the PDMA engine for TX.
