b749646dad net/sfc/base: add function to create packed stream RxQ
Encoding packed stream buffer size in RxQ type is not a future-proof
idea taking into account a new RxQ types with extra parameters.
To be consistent make packet stream buffer size a separate parameter.
In order to avoid blowing of the default RxQ create function prototype
add a dedicated function to create packed stream RxQ without not
applicable paramters.

ede62b5a56 net/sfc/base: more accurately calculate number of PS credits
Maximum number of packets per 64k buffer should be rounded up
when calculating number of credits by event queue size.

3bdf5f1721 net/sfc/base: optimize credits overflow check
Apply check against firmware maximum just before pushing.
However, it does not save from overflow inside firmware,
if firmware still have some credits.

d8115cadb3 net/sfc/base: clarify meaning of Rx desc lbits in PS mode
There is no point to add mask plus one before mask applying since it
still does not help to avoid overflow on subtract. Modulo mask
arithmetic works perfectly for unsigned integers of the same type.

af39bcc612 net/sfc/base: let caller know that queue is already flushed
Tx/Rx queue may be already flushed due to Tx/Rx error on the queue or
MC reboot. Caller needs to know that the queue is already flushed to
avoid waiting for flush done event.

c01e77c44d net/sfc/base: import Rx packed stream mode
In packed stream mode, large buffers are provided to the NIC
into which many packets can be delivered. This reduces the
number of queue refills needed compared to delivering every
packet into a separate buffer.

EFSYS_OPT_RX_PACKED_STREAM should be enabled to use it.

8c7c723dfe net/sfc/base: import MAC statistics
MAC statistics are either periodically (if supported/requested)
or on-demand written to provided DMA-mapped memory.
If periodic update is not supported (e.g. for EF10 virtual
functions), it is the driver responsibility to handle it.

EFSYS_OPT_MAC_STATS should be enabled to use it.
