Also update comments and assertions in io.h:
- EF10 does not have a general BIU collector and does not have the
bug affecting TIMER_COMMAND_REG[0] on Falcon/Siena
- The WPTR field moved within RX_DESC_UPD_REG and TX_DESC_UPD_REG.

The TX path firmware for EF10 supports 'option descriptors' to control

On EF10, the firmware will initiate a queue flush in certain
error cases. We need to accept that flush events might appear
at any time after a queue has been initialised, not just when
we try to flush them.
We can handle Falcon-architecture in just the same way.

RX DMA scatter is always enabled on EF10. Adjust the common RX
completion handling to allow for this.
RX completion events on EF10 include the length used from a single
descriptor, not the cumulative length used. Add a field to struct
efx_rx_queue to hold the cumulative length.

This function checks the upper bound but it doesn't check for negative
numbers:
if (txq > QLCNIC_MAX_TX_RINGS) {
I've solved this by making "txq" a u32 type. I chose that because
->tx_count in the ethtool_channels struct is a __u32.

The Huntington MC will reject all MCDI requests after an MC reboot until it sees
one with the NOT_EPOCH flag clear. This flag is set by default for all requests,
and then cleared on the first request after we detect that an MC reboot has
occurred.
The old MCDI_STATUS_DELAY_COUNT gave a timeout of 10ms, which was not long enough
for the driver to detect that a reboot had occurred based on the warm boot count
while calling efx_mcdi_poll_reboot() from the loop in efx_mcdi_ev_death().

Various hardware statistics that are available for Siena are
unavailable or meaningless for Falcon. Huntington adds further to the
NIC-type-specific statistics, as it has different MAC blocks from
Falcon/Siena.
All NIC types still provide most statistics by DMA, and use
little-endian byte order.
Therefore:
1. Add some general utility functions for reporting hardware statistics,
efx_nic_describe_stats() and efx_nic_update_stats().
2. Add an efx_nic_type::describe_stats operation to get the number and
names of statistics, implemented using efx_nic_describe_stats()
3. Change efx_nic_type::update_stats to store the core statistics
(struct rtnl_link_stats64) or full statistics (array of u64) in a
caller-provided buffer. Use efx_nic_update_stats() to aid in the
implementation.
4. Rename struct efx_ethtool_stat to struct efx_sw_stat_desc and
EFX_ETHTOOL_NUM_STATS to EFX_ETHTOOL_SW_STAT_COUNT.
5. Remove efx_nic::mac_stats and struct efx_mac_stats.

Merge the per-NIC-type MTD probe selection and struct efx_mtd_ops into
struct efx_nic_type. Move the implementations into the appropriate
source files.
Several NVRAM functions are now only called from MTD operations which
are now implemented in the same file (falcon.c or mcdi.c). There is no
need for them to be extern, or to be defined at all if CONFIG_SFC_MTD
is not enabled, so move them into the #ifdef CONFIG_SFC_MTD sections
in those files.
Most of the SPI-related definitions are also only used in falcon.c,
so move them there. Put the remainder of spi.h into nic.h (which
previously included it).
