Currently, if info is null, the dev_err message is dereferencing an

There are two protocols used by Broadcom FullMAC devices: BCDC and
msgbuf. They use different ways for (some part of) communication with
the firmware. Firmware Signaling is required for the first one only
(BCDC).
So far we were always initializing fws and always calling it's

It's not needed by the other (msgbuf) protocol, so let's save some size
and compile it conditionally.

There is no check if ioremap_nocache() returns a valid pointer.
Potentially it can lead to null pointer dereference.

If 'clk_hw_register()' fails, it is likely that we expect to return an
error instead of a valid pointer (which would mean success).
'clk_hw_register()' returns a bool, so we don't have the detail of the
error. Return -ENOMEM instead, as it seems to be the most common error
returned by clk_register(
The definition of the flush hint table as:
void __iomem *flush_wpq[0][0];
...passed the unit test, but is broken as flush_wpq[0][1] and
flush_wpq[1][0] refer to the same entry. Fix this to use a helper that
calculates a slot in the table based on the geometry of flush hints in
the region

Ok, so that code actually has a chance of being used. I guess we'll

Send an immediate ACK if we fill in a hole in the buffer left by an
out-of-sequence packet. This may allow the congestion management in the peer
to avoid a retransmission if packets got reordered on the wire.

Send an ACK if we haven't sent one for the last two packets we've received.
This keeps the other end apprised of where we've got to - which is
important if they're doing slow-start.
We do this in recvmsg so that we can dispatch a packet directly without the

If we've sent all the request data in a client call but haven't seen any

find out if the reply data got lost.
If the server hasn't yet hard-ACK'd the request data, we send a PING ACK to

When determining the resend timer value, we have a value in nsec but the

Implement RxRPC slow-start, which is similar to RFC 5681 for TCP. A
tracepoint is added to log the state of the congestion management algorithm
and the decisions it makes.

Clear the ACK reason, ACK timer and resend timer when entering the client
reply phase when the first DATA packet is received. New ACKs will be
proposed once the data is queued.
The resend timer is no longer relevant and we need to cancel ACKs scheduled
to probe for a lost reply.
