      sfc: Remove efx_nic_type::push_multicast_hash operation · 30b81cda
      由 Ben Hutchings 提交于 
      Both implementations of efx_nic_type::reconfigure_mac operation
push the multicast hash filter to the hardware.  It is therefore
redundant to call efx_nic_type::push_multicast_hash as well.

efx_mcdi_mac_reconfigure() also uses this operation, but the
implementation for Siena just uses MCDI anyway.  Merge that into
efx_mcdi_mac_reconfigure().

      sfc: Merge efx_mcdi_mac_check_fault() and efx_mcdi_get_mac_faults() · 1daf4170
      由 Ben Hutchings 提交于 
      The latter is only called by the former, which is a very short
wrapper.  Further, gcc 4.5 may currently wrongly warn that the
'faults' variable may be used uninitialised.

      sfc: Merge efx_mac_operations into efx_nic_type · 710b208d
      由 Ben Hutchings 提交于 
      No NICs need to switch efx_mac_operations at run-time, and the MAC
operations are fairly closely bound to NIC types.

Move efx_mac_operations::reconfigure to efx_nic_type::reconfigure_mac
and efx_mac_operations::check_fault fo efx_nic_type::check_mac_fault.
Change callers to call through efx->type or directly if the NIC type
is known.

Remove efx_mac_operations::update_stats.  The implementations for
Falcon used to fetch MAC statistics synchronously and this was used by
efx_register_netdev() to clear statistics after running self-tests.
However, it now only converts statistics that have already been
fetched (and that only for Falcon), and the call from
efx_register_netdev() has no effect.

      sfc: Hold efx_nic::stats_lock while reading efx_nic::mac_stats · 1cb34522
      由 Ben Hutchings 提交于 
      efx_nic::stats_lock is used to serialise stats updates, but each
reader was dropping it before it finished reading efx_nic::mac_stats.

If there were concurrent stats reads using procfs, or one using procfs
and one using ethtool, an update could race with a read.  On a 32-bit
system, the reader could see word-tearing of 64-bit stats (32 bits of
the old value and 32 bits of the new).

      sfc: Use new names for MC shared memory layout constants · 788ec41c

      These are defined alongside the firmware protocol in mcdi_pcol.h.

      sfc: Make handling of MC reboot more reliable · 3f713bf4
      由 Ben Hutchings 提交于 
      When the MC reboots, either as part of a firmware upgrade or due to a
bug, it attempts to complete (with an error) any requests that were
outstanding before the reboot.  Since there is an inherent race
condition in checking this, it will also write to a status word in
shared memory.

If we look at each of these separately, we may detect each reboot
twice, resulting in a spurious command failure after a firmware
upgrade or frustrating recovery from a firmware bug.  Instead, if a
request completion indicates a reboot, we must poll and clear the
status word.

This bug was previously masked by use of an incorrect address for the
status word.  Fix that, using the definition now included in
mcdi_pcol.h.

      sfc: Remove fallback for invalid permanent MAC address · e332bcb3
      由 Ben Hutchings 提交于 
      By the time we look at the MAC address in efx_probe_port(), either the
driver or the firmware has already validated the board configuration.
The possibility of having an invalid MAC address just isn't worth
considering.  It certainly isn't worth having a compile-time option
for this.
